No. 16/194,693, filed Nov. 19, 2018, now U.S. Pat. No. 10,546,516, issued Dec. 24, 2019; which is a continuation of U.S. patent application Ser. No. 13/837,575, filed Mar. 15, 2013, now U.S. Pat.

     BACKGROUND 
     In residential or commercial environments, a number of devices may be part of an energy control network, for example a smart home or commercial energy network. The devices of an energy control network may be used to control energy consumption, such as but not limited to lighting sources and heating resources. Such load control devices may communicate with one another via a wired or wireless network. Devices such as a dimmer switch, a plug-in load control device (PID), a temperature control device, a contact-closure output (CCO) pack, a remote controller, an occupancy sensor, a temperature sensor, a digital ballast controller, a motorized window treatment, a battery-powered remote control, an occupancy sensor, and/or a daylight sensor, among other devices, may be part of an energy control network. Examples of additional devices that may be part of such energy control networks are described in greater detail in commonly-assigned U.S. patent application Ser. No. 13/234,758, filed Sep. 16, 2011, entitled LOAD CONTROL SYSTEM HAVING AN ENERGY SAVINGS MODE, the entire disclosure of which is hereby incorporated by reference. 
       FIG. 1  illustrates an example of load control system (or an energy control network). As shown in  FIG. 1 , a user  112  may operate a lighting control device, such as a dimmer switch  106  for controlling a lighting load  132 , and/or motorized window treatments  110  in room  130  using a remote control device  104  (e.g., a LUTRON® PICO® wireless remote control device). In addition, the dimmer switch  106  and/or the motorized window treatments  110  may be controlled automatically in response to an occupancy sensor  134 . Also, the user  112  may use a temperature control device  102  to adjust a heating, air-conditioning, and ventilation (HVAC) system to control the temperature in the room  130 . Similar systems have been developed to incorporate the use of other wireless devices (e.g., tablets and/or cellular phones) as remote load controls. 
     The temperature control device  102  may have a user interface that includes an “up” arrow and a “down” arrow to facilitate the adjustment of a temperature setpoint for the area that the temperature control device monitors and controls. The remote control device  104  may have a user interface that includes one or more buttons that can be used for functions like sending a “raise” and/or “lower” command to a shade control device, or perhaps an “on” or “off” (or assume a predetermined lighting “scene” command) to one or more lighting loads, like lighting load  132 . The remote control device  104  may have more than two buttons (e.g. five buttons) that may be configured for effectuating five respective lighting scenes. Also, the dimmer switch  106  may have two buttons with which the user  112  can either raise or lower an intensity of the lighting load  132 . 
     At the time of manufacture, a device that may become a part of an energy control network may be provided with a default (or initial) database that may correspond to the general functionality of the device. For example, the dimmer switch  106  at the time of manufacture may be provided with an initial dimmer switch database (or configuration) that may be downloaded to one or more, or all, dimmer switches at the time of manufacture. For example, downloading the initial device database to the dimmer switch  106  at the time of manufacture may involve establishing a physical electronic connection to the dimmer switch at some point in the process of manufacturing the dimmer switch  106 . The initial device database can be downloaded to the dimmer switch  106 , and at the time manufacturing is complete the dimmer switch  106  can be shipped to an end user, retail distributor, and/or installation contractor, for example. 
     When selected by an end user and/or installation contractor, a load control device may require that its initial database be replaced with a database specific to the particular device&#39;s actual functions and/or configuration. For example, dimmer switch  106  may require the specific device configuration that it is a two-button dimmer switch. Also by way of example, dimmer switch  106  may have illuminated push buttons (e.g. backlit) or may have other indicator lights (not shown). The specific device database downloaded to dimmer switch at the time it is installed (or replaced) may provide the dimmer switch  106  with the configuration corresponding to operation with the two backlit buttons and/or other indicator lights—where the initial database provided to the dimmer switch  106  at the time of manufacture may not provide such a specific corresponding configuration. The specific device database may be downloaded to the dimmer switch  106  via a physical electronic connection, or perhaps via a special sequence of inputs made through the buttons of the dimmer switch  106 , which may be both cumbersome and time consuming. Also, the load control device may be added to a wireless communication network so that the specific device database may be provided via a protocol of the wireless communication network (e.g., the Wi-Fi protocol or the Clear Connect™ protocol). Adding the device to such a wireless communication network may also be both cumbersome and time consuming. 
     Also at the time a load control device is put into a specific application by an end user and/or contractor, a first load control device may be provided with information regarding the other load control devices with which the first load control device may wirelessly communicate. For example, the first load control device may communicate with the other load control devices on an energy control communications network (e.g. a Wi-Fi based network or a wireless proprietary protocol network). Such energy control communications network information (e.g. network addresses of devices to monitor and/or control) may be downloaded to the dimmer switch  106  via a physical electronic connection, or perhaps via a special sequence of inputs made through the buttons of the dimmer switch  106  (which again may be both cumbersome and time consuming). Also, the load control device may be added to a wireless communication network so that the energy control communications network information may be provided via a protocol of the wireless communication network (e.g., the Wi-Fi protocol or the Clear Connect™ protocol). And adding the device to such a wireless communication network may also be both cumbersome and time consuming. 
     After providing the load control device with its specific device database and also after providing the load control device with the information required to communicate with other load control devices, the user interface of the load control device may be used to bring about the user-desired effects that the load control device has been specifically configured to provide. For example, a user can use the buttons of the dimmer switch  106  to increase or decrease the intensity of one or more lighting loads connected to the dimmer switch  106 . However, the user is limited to the specific functionality provided by the particular configuration of the dimmer switch&#39;s  106  user interface. In other words, the user is limited to the functions provided by the two buttons on the dimmer switch  106 , where the dimmer switch  106  may be specifically configured for more functionality than can be accessed by the two button user interface. 
     Should a load control device fail or become inoperative to perform its configured functions, then the inoperative device may require physical replacement. At the time the load control device is replaced, an end user and/or contractor may wish to provide the replaced load control device with the specific device database that was provided to the previous (now inoperative) load control device. To accomplish this, the end user and/or contractor may use the same techniques as were used to provide the previous load control device with its specific device database and load control network information. For example, that information may be downloaded to a replacement load control device via a physical electronic connection, or perhaps via a special sequence of inputs made through the user interface of the replacement load control device. Also, the replacement load control device may be added to a wireless communication network so that the specific device database may be provided via a protocol of the wireless communication network (e.g., the Wi-Fi protocol or the Clear Connect™ protocol). As mentioned previously, adding the device to such a wireless communication network may also be both cumbersome and time consuming. 
     Near Field Communication (NFC) is an emerging wireless data transfer protocol. Little network or administrative configuration may be needed to establish NFC protocol based wireless communication. And NFC may facilitate the wireless transfer of data at low data rates and within a relatively limited geographic range. It may be useful to utilize NFC for the purposes of managing the databases of load control devices and/or exploiting the configurable flexibility of load control device user interfaces. 
     SUMMARY 
     A load control device, perhaps at a time of manufacture, may be provided with a default (e.g. initial) database for a type of device that may correspond to the load control device. An initial device database may be selected based on the type of load control device and the selected initial database may be downloaded to the load control device via a low data rate and close proximity wireless protocol. 
     A load control device, perhaps at a time of installation, may be provided with a specific database for a type of device that may correspond to the load control device. A specific device database may be selected based on the type of load control device and the specific configuration of the load control device. The selected specific device database may be downloaded to the load control device via a low data rate and close proximity wireless protocol. 
     A load control device, perhaps at a time of installation, may be provided with a network database that may correspond to the load control device. A network database may be selected based on an energy control network that may correspond to a specific load control device. The selected network database may be downloaded to the load control device via a low data rate and close proximity wireless protocol. 
     A wireless control device may receive a signal from a load control device that may allow the wireless control device to display a specific user interface for the load control device. The wireless control device may receive a signal via a low data rate and close proximity wireless protocol. The signal may contain information that may identify the load control device. The wireless control device may determine a specific access level based on an identified load control device. If at least some access level is determined, the wireless device may display a user interface for the load control device specific to the determined level of access. 
     A load control device may be commanded to make an adjustment to one or more electrical loads in connection with the load control device. The command sent to the load control device may be originated by wireless communication between a wireless control device and a radio frequency identification (RFID) device via a low data rate and close proximity wireless protocol, for example near field communication (e.g. via an NFC tag). 
     A device database for a load control device may include a configuration for particular operation of the load control device. Should the load control device become inoperative for the configured operation, the device database of the inoperative load control device may be uploaded via a low data rate and close proximity wireless protocol. The uploaded device database may be downloaded to another load control device that may be operative for the configured operation via the low data rate and close proximity wireless protocol.

     DETAILED DESCRIPTION 
     Near Field Communication (NFC) is a reference to a collective of standards for wireless communication devices, such as “smart” cellular telephones, tablets, and laptops, among others, to establish radio communication with other such devices. NFC communication among NFC enabled devices may occur by touching the devices together or by bringing them into relatively close proximity, for example perhaps no more than a few centimeters. Applications of NFC include retail transactions and data transfer, or data exchange, among others. NFC may also occur between an NFC device (e.g., an NFC enabled device under power) and an unpowered, but otherwise functional, NFC module, or an unpowered device including an NFC module. For example, an NFC enabled device may communicate (via NFC) with a radio-frequency identification (RFID) device (e.g. an NFC tag). NFC may also enable a relatively simple setup of more complex communications, such as Wi-Fi Communication or Bluetooth, for example. The ease of establishing NFC may have certain tradeoffs. For example, NFC may provide for a relatively low rate of data exchange or transfer (e.g., low bandwidth communication). And NFC may not be considered a particularly reliable or secure wireless communication protocol, for example as compared to other wireless communication protocols (e.g., the Wi-Fi communication protocol). As referred to herein, an NFC tag and/or an RFID tag may include active and/or passive devices. For example, a passive NFC tag device or RFID tag device may be a sticker or a label that may receive power from radio frequency energy. An active NFC tag device or RFID tag device may include an powered NFC circuit (e.g., as may be located inside a load control device). 
       FIG. 2A  is an example of an initial (e.g. default) configuration of a load control device via near field communication (NFC). By way of example, and not limitation, load control devices  1002 A,  1002 B,  1002 C, and  1002 D may be any of a number of load control devices, such as dimmer switches, occupancy sensors, remote control devices, temperature control devices, among other load control devices. Manufacturers may produce load control devices of a particular general type in relatively large numbers. For example, for the purpose of cost efficiencies and market demands, among other reasons, a manufacturer may produce large numbers of dimmer switches at a given time. And at other times or perhaps at a time parallel to the production of the dimmer switches, the manufacturer may produce large numbers of occupancy sensors or remote control devices. For purposes of explanation, the load control devices  1002 A,  1002 B,  1002 C, and  1002 D may be multi-button remote control selector switch devices. 
     At the time of manufacture, the manufacturer may not have sufficient information from which to provide the multi-button remote control selector switch devices  1002 A- 1002 D with a specific device configuration. For example, an end-user who purchases (e.g. at some point in time) the respective load control devices  1002 A- 1002 D, may have a particular operational configuration (or database) in mind for the device or devices that are purchased. Again by way of example, an end-user may purchase a three-button remote control selector switch for a kitchen area. Continuing the example, the first button of the three-button remote control selector switch device may, when activated by the end-user, effectuate a first particular lighting scene in the kitchen area. And the end-user may activate the second button and/or the third button of the three-button remote control selector switch device to effectuate a respective second and/or third lighting scene in the kitchen area. But load control device manufacturers often may not have knowledge of such specific device configurations for the load control devices  1002 A- 1002 D that may be purchased by end-users. Thus, at the time of manufacture, the load control devices  1002 A- 1002 D may not be provided with a specific device configuration (or database). 
     In addition to situations in which the manufacturer may not have sufficient information to develop a specific device configuration (or database), perhaps again for purposes of cost efficiencies, the manufacturer may wish to provide the load control devices  1002 A- 1002 D with no more than an initial (or default) configuration (or database). The initial database may be based at least in part on the general type of the load control devices  1002 A- 1002 D. For example, the general type of the load control devices  1002 A- 1002 D may be a multi-button remote control device, for example. By providing at least an initial database for the load control devices  1002 A- 1002 D at a time proximate to manufacture, the manufacturer may provide basic operational database parameters for the respective load control devices  1002 A- 1002 D. The basic operational database parameters may be useful for the implementation of the specific device database that may be provided to the load control devices  1002 A- 1002 D by an end-user. Also, providing the initial database may permit the manufacturer to determine the respective load control devices&#39;  1002 A- 1002 D general ability to accept a transfer of data, such as a download of database information, for example. 
     For example, at a time of manufacture, load control devices  1002 A- 1002 D may be provided with an initial database for a multi-button remote control device using a wireless control device  1006 . The wireless control device  1006  (e.g. a wireless control device) may be configured to communicate via at least two wireless communication protocols. For example, the wireless control device  1006  may include a first communication module that may be configured to wirelessly transmit and/or receive radio frequency (RF) signals  210  via a Wi-Fi protocol and/or a proprietary RF protocol such as Clear Connect™, among other RF protocols. The wireless control device  1006  may also include a second communication module that may be configured to wirelessly transmit and/or receive signals  208  via a close proximity and low data rate wireless protocol, such as the NFC protocol. 
     The wireless control device  1006  may communicate with a general load control device database  1008  via the RF signals  210  to obtain an initial database for a type of load control device. For example, a type of load control device may be entered into the wireless control device  1006 . Based on the entered type of load control device, the wireless control device  1006  may search an internal memory for the initial device database for the load control device. If the wireless control device  1006  may not find the initial device database corresponding to entered type of load control device, the wireless control device  1006  may obtain the initial device database from the general load control device database  1008  via RF signals  210 . When the wireless control device  1006  either locates and/or obtains the initial device database corresponding to the entered type of load control device, the wireless control device  1006  may transfer the initial device database to the respective load control device  1002 A- 1002 D via NFC signals  208 . 
       FIG. 2B  is a flowchart of an example technique to download an initial configuration of a load control device via near field communication (NFC). At a starting point  2002 , perhaps at some time proximate to the manufacture of a load control device or devices (e.g., load control devices  1002 A- 1002 D, a manufacturer may decide to provide an initial database to the load control device. At  2004 , an initial device database may be selected (e.g., at the wireless control device  1006 ), perhaps based on a load control device type (e.g., a multi-button remote control device). At  2006 , the selected initial database may be downloaded to the load control device via a low data rate and close proximity wireless protocol (e.g. NFC signaling  208 ). At  2008 , a successful initial database download may be confirmed (e.g., by the wireless control device  1006 ). At  2010 , upon a successful initial device database download, the technique may end. If a successful download of the initial device database to the load control device is not confirmed, then the download of the initial device database via NFC signaling may be repeated (e.g., until successful and/or for a predetermined period of time). 
       FIG. 3A  is an example specific device configuration via near field communication (NFC) upon an installation of a load control device. The load control device may be a multi-button remote control selector switch  202  with operational functionality similar to that described with respect to the remote control device  104 . For example, by activating a first button of the remote control selector switch  202 , a user  112  may effectuate a first preconfigured “scene” (e.g., certain lights set to a preconfigured level of intensity, certain shades set to a preconfigured extension length, etc.). Other buttons of the remote control selector switch  202  may effectuate other respective scenes, for example. Perhaps after either installing the remote control selector switch  202  for an initial installation, or perhaps after replacing a previously installed multi-button remote control selector switch  202  with a new unit for some reason, the newly installed multi-button remote control selector switch  202  may be operating with its initial configuration (e.g. a default configuration or database). 
     The user  112  may use a wireless control device  204  (e.g. a “smart” cellular phone) to provide the multi-button remote control selector switch  202  with a specific device configuration via NFC signaling  208 . For example, the multi-button remote control selector switch  202  may be a two button remote control selector switch (as depicted in  FIG. 3A ). The wireless control device  204  may have a load control device application interface (API) that may enable the user  112  to select an appropriate specific device configuration (e.g. a specific device database) for a two button remote control device, like multi-button remote control selector switch  202 . Also, the user  112  may select a specific device database for the newly installed multi-button remote control device  202  (e.g., button number one is configured to effectuate a first defined scene, and button number two is configured to effectuate a second defined scene). 
     The API on the wireless control device  204  may also enable the user  112  to provide the multi-button selector switch  202  via the NFC signaling  208  with information regarding a network (e.g., an energy control network) with which the multi-button selector switch device  202  may communicate. For example, the newly installed multi-button remote control selector switch device  202  may be provided with access information (e.g., network identifiers and/or security passwords, etc.) for a wireless communication network (e.g., a Wi-Fi network or a Clear Connect™ wireless network). And the API may provide the multi-button remote control selector switch  202  with the addresses of other load control devices with which the multi-button remote control selector switch  202  may communicate via the wireless communication network. For example, the multi-button remote control selector switch  202  may be provided via NFC signaling  208  with the wireless communication network addresses of the respective lighting loads and/or shades, etc., that may be part of the configured scenes respectively associated with the buttons of the multi-button remote control selector switch  202 . 
       FIG. 3B  is a flowchart of an example technique to download a specific device database of a load control device via near field communication (NFC). At  3002 , a load control device (e.g., the multi-button remote control selector switch  202  of  FIG. 3 ) may be installed. At  3004 , a device specific database may be selected (e.g., at the wireless control device  204 ), perhaps based on a device type (e.g., a multi-button remote control selector switch device), a device configuration (e.g., the two button remote control selector switch  202 ), and/or where the two buttons may be configured to effectuate certain predefined scenes as desired by the end-user. At  3006 , the selected device specific database may be downloaded to the load control device via a low data rate and close proximity wireless protocol (e.g. NFC signaling  208 ). At  3008 , a successful specific database download may be confirmed (e.g., by the wireless control device  204 ). At  3010 , upon a successful specific device database download, the technique may end. If a successful download of the specific device database to the load control device is not confirmed, then the download of the specific device database via NFC signaling may be repeated (e.g., until successful and/or for a predetermined period of time). 
       FIG. 3C  is a flowchart of an example technique to download a load control network configuration of a load control device via near field communication (NFC). At  3050 , a load control device (e.g., the multi-button remote control selector switch  202  of  FIG. 3 ) may be installed. At  3052 , a network database may be selected (e.g., at the wireless control device  204  of  FIG. 3 ), perhaps based on an energy control network corresponding to the load control device. At  3054 , the selected network database may be downloaded to the specific load control device via a low data rate and close proximity wireless protocol (e.g. NFC signaling  208 ). At  3056 , a successful network database download may be confirmed (e.g., by the wireless control device  204 ). At  3058 , upon a successful network database download, the technique may end. If a successful download of the network database to the load control device is not confirmed, then the download of the network database via NFC signaling may be repeated (e.g., until successful and/or for a predetermined period of time). 
       FIG. 4A  is a first example of a display of a load control device specific user interface on a wireless device using NFC. A load control device  302 , which for purposes of explanation may be a two-button remote control selector switch, may include a RFID device  320 . The RFID device  320  may be located within an enclosure of the two-button remote control selector switch  302 , for example. Alternatively or additionally, the RFID device  320  may be located on the exterior or proximate to the enclosure of the two-button remote control selector switch  320 . The RFID device  320  may include a command script that may be interpretable (e.g. via a NFC communication module of the two-button remote control selector switch  302 —not shown) by a controller (not shown) of the two-button remote control selector switch  302 . The command script of the RFID device  320  may include instructions that control the operation or functions of the two-button remote control selector switch  302 . For example, the command script of the RFID device  320  may instruct the controller of the two-button remote control selector switch  302  as to what scene the respective two buttons may effectuate when activated by a user. 
     The wireless control devices  304 ,  306 , and/or  308  (e.g., “smart” cellular phones or tablets) may communicate with the two-button remote control selector switch  302  via NFC signals  208  (e.g., via the NFC communication modules of the two-button remote control selector switch  302  and the wireless control devices  304 ,  306 , and/or  308 —not shown). The RFID device&#39;s  320  command script may be reconfigured via the NFC signaling  208  from one or more of the wireless control devices  304 ,  306 ,  308  that the RFID device  320  (and/or the RFID device&#39;s  320  command script and/or the two-button remote control selector switch  302 ) may be recognize as having the appropriate authority to reconfigure the RFID device&#39;s  320  command script. Appropriate authority may be determined by the RFID device  320  (and/or the RFID device&#39;s  320  command script and/or the two-button remote control selector switch  302 ) command script recognizing a respective identification (e.g. respective serial numbers) of the wireless control devices  304 ,  306 , and/or  308 . The respective serial numbers of the wireless control devices  304 ,  306 , and/or  308  may be communicated via the NFC signals  208 . Also, the two-button remote control selector switch  302  may also have a serial number that may be communicated via the NFC signals  208 . Appropriate authority and/or access level may be determined, for example, by that authority or access level that may be built into wireless control devices  304 ,  306 , and/or  308 . Also by way of example, the two-button remote control selector switch  302  may read the serial number off of the wireless control devices  304 ,  306 , and/or  308  and may alter the RFID device&#39;s  320  command script for a particular session. 
     The wireless control devices  304 ,  306 , and/or  308  may be configured (e.g., a controller of the wireless control devices  304 ,  306 , and/or  308 —not shown) to display device specific (or device user specific) graphical user interface (GUI) representations of the two-button remote control selector switch  302 . The device specific GUI representations may be determined by the respective wireless control devices  304 ,  306 , and/or  308  based, at least in part, on the two-button remote control selector switch&#39;s  302  serial number as may be communicated via the NFC signals  208 . For example, the GUI of wireless control device  304  may represent five virtual buttons, the GUI of wireless control device  306  may represent four virtual buttons, and the GUI of wireless control device  308  may represent one virtual button. The device specific GUI representations may provide for unique control of the two-button remote control selector switch  302  by the respective wireless control devices  304 ,  306 , and/or  308 . 
     For example, the GUI of the wireless control device  304  may provide a user with a five virtual button operational configuration of the two-button remote control selector switch  302 . And the virtual button operational configuration of the GUI of wireless control device  304  may be different than the functions of the two buttons of the two-button remote control selector switch  302  as configured on the controller of the two-button remote control selector switch  302  and/or the RFID device&#39;s  320  command script. For example, the controller of the two-button remote control selector switch  302  and/or the RFID device&#39;s  320  command script may recognize the serial number of the wireless control device  304 ,  306 , and/or  308  that may be sending a command to effectuate the function (or different function or different “scene”) and, perhaps upon confirming the wireless control device&#39;s  304 ,  306 , and/or  308  authority or access level, may implement the commanded function. Security considerations may be satisfied where the two-button remote control selector switch  302  and/or the RFID device&#39;s  320  command script may request and/or confirm an authority or access level for a commanded function. Authority and/or access levels may vary among the respective wireless control devices  304 ,  306 , and/or  308  and/or users thereof. 
     By way of further example, the first virtual button of the GUI of the wireless device  304  may, when activated by a user, effectuate a different scene than would be effectuated by the user physically activating the first button on the two-button remote control selector switch  302 . The scene effectuated by the first button of the GUI of the wireless device  304  may be a personalized scene preferred and preconfigured by a user of the wireless device  304 . Further, the second virtual button of the GUI of the wireless device  304  may, when activated by a user, effectuate a different scene than would be effectuated by the user physically activating the second button on the two-button remote control selector switch  302 . The three other virtual buttons of the GUI of wireless device may effectuate other personalized scenes for the user of the wireless device  304 . In a similar fashion, the four virtual buttons presented by the GUI of wireless control device  306  may effectuate four respectively personalized scenes for the user of the wireless device  306 . And the one virtual button presented by the GUI of wireless control device  308  may effectuate one personalized scene for the user of the wireless device  306 . 
     Alternatively or additionally, the functions of the two buttons of the two-button remote control selector switch  302  as configured on the controller of the two-button remote control selector switch  302  and/or the RFID device&#39;s  320  command script may be changed based on the NFC signal  208  interaction with one or more of the wireless control devices  304 ,  306 , and/or  308 . For example, the GUI representation of the wireless control device  304  may provide for a function that, when implemented by a user of the wireless control device  304 , may send a command to the two-button remote control selector switch  302  to reconfigure the functions of either one or both of the two buttons of the two-button remote control selector switch  302 . The commanded reconfiguration may occur on the controller of the two-button remote control selector switch  302  and/or on the RFID device&#39;s  320  command script. The commanded reconfiguration of either one or both buttons two-button remote control selector switch  302  may occur after the controller of the two-button remote control selector switch  302  and/or the RFID device  320  confirms that the wireless control device  304  has the appropriate authority or access level to command such a reconfiguration. 
     For example, when a user of the wireless control device  304  implements the reconfiguration function (and perhaps after an authority and/or access level may be requested and/or confirmed), the functions or scenes effectuated by one or both physical buttons of the two-button remote control selector switch  302  may be changed. The changed functions or scenes of one or both physical buttons of the two-button remote control selector switch  302  may mirror the functions or scenes that may be effectuated by the first virtual button and/or the second virtual button of the GUI representation of the wireless control device  304 . Alternatively or additionally, the changed functions or scenes of one or both physical buttons of the two-button remote control selector switch  302  may mirror the functions or scenes that may be effectuated by one of the other virtual buttons of the GUI representation of the wireless control device  304 , for example. 
     Alternatively or additionally, the controller of the two-button remote control selector switch  302  and/or the RFID device  320  may be configured to change (or reconfigure) the functions of one or both buttons of the two-button remote control selector switch  302  upon detecting NFC signaling  208  with one or more of the wireless control devices  304 ,  306 , and/or  308 . The controller of the two-button remote control selector switch  302  and/or the RFID device  320  may request and/or confirm that the wireless control device  304  has an authority or access level corresponding to a reconfiguration upon detection of NFC signaling  208 . Such a confirmation may be based on the serial number of the wireless control device  304  as communicated via NFC signaling  208 . After the authority or access level may be confirmed, the controller of the two-button remote control selector switch  302  and/or the RFID device&#39;s  320  command script may change (or reconfigure) the functions of one or both of the buttons of the two-button remote control selector switch  302 . The functions of one or both of the buttons of the two-button remote control selector switch  302  may remain as they were reconfigured, perhaps until the functions are changed once again by NFC signaling  208  interaction with another wireless control device (e.g. wireless control device  306 ) with the appropriate authority or access level to cause such a reconfiguration. 
       FIG. 4B  is second example of a display of a load control device specific user interface on a wireless device using NFC.  FIG. 4B  includes a blank-face (e.g. no physical button or manual operators) remote control device  316 . The blank-face remote control device  316  may function in a similar manner as the two-button remote control selector switch  302  of  FIG. 4A , with the exception that a user may not effectuate any functions (or scenes) via physical contact with the blank-face remote control device  316 . The functions, elements, and interactions of the RFID device  320  and the wireless control devices  304 ,  306 , and/or  308  may be the same or similar as those described with regard to  FIG. 4A . By using the blank-face remote control device  316 , a higher level of security considerations may be satisfied. For example, one or more, or all, of the functions controlled by the blank-face remote control device  316  may be implemented via commands generated from the personalized GUI representations of the respective wireless control devices  304 ,  306 , and/or  308 . And the blank-face remote control device  316  may request and/or confirm an authority or access level for the respective commands before effectuating the respective commands. 
       FIG. 4C  is a flowchart of an example technique to display a load control device user interface via NFC. At  5002 , a user may place a first device (e.g. wireless control device  304 ) in close proximity with a second device (e.g. a load control device like the two-button remote control selector switch  302 ) as a starting point. At  5004 , the first device may receive a signal via a low data rate and close proximity wireless protocol (e.g. NFC signaling  208 ). At  5006 , the second device may be identified based on information contained in the signal (e.g. a serial number of the load control device). At  5008 , a specific access level may be determined by the first device based the identified second device. At  5010 , the first device may determine if at least some specific access level exists. At  5012 , upon determining that a specific access level exists, a user interface corresponding to the determined specific access level may be displayed on the first device. At  5014 , the technique may end after the user interface corresponding to the determined specific access level is displayed, which may provide a user of the first device with user-specific control access for the second device. 
       FIG. 4D  is a flowchart of an example technique to operate a load control device via near field communication (NFC). At  5020 , a user may place a first device (e.g. wireless control device  304 ) in close proximity with a second device (e.g. a load control device like the two-button remote control selector switch  302 ) as a starting point. At  5022 , the second device may receive a signal via a low data rate and close proximity wireless protocol (e.g. NFC signaling  208 ). At  5024 , the first device may be identified based on information contained in the signal (e.g. a serial number of the wireless control device  304 ). At  5026 , a command may be identified based on information contained in the signal (e.g. a command to effectuate a particular lighting scene). At  5028 , a specific access level may be determined by the second device based the identified first device. At  5030 , the second device may determine if at least some specific access level exists. At  5032 , upon determining that a specific access level exists, the command may be executed by the second device. At  5034 , the technique may end after the command is executed, which may provide a user of the first device with a desired lighting scene. 
       FIG. 5A  depicts a first example adjustment of a lighting load in a load control network  500 A with an interaction between a wireless device and a radio-frequency identification (RFID) device via near field communication (NFC). An RFID device  510 A, that may include a command script (not shown), may communicate via NFC signals  208  with a wireless control device  514 A. The RFID device&#39;s  510 A command script may be configured to send an identification of the RFID device  510 A, such as but not limited to a serial number and/or a custom integration string of the RFID device  510 A, when the wireless control device  514 A comes into a proximity sufficient for NFC based communication. 
     The wireless control device  514 A (and/or a receiver of the wireless control device  514 A—not shown) may be configured to receive the serial number for RFID device  510 A and/or the custom integration string for RFID device  510 A. Upon receipt of the serial number and/or the custom integration string for RFID device  510 A via the NFC signaling  208 , the wireless control device  514 A (and/or a controller of the wireless control device  514 A—not shown) may be configured to initiate a wireless transmission (e.g. via a transmitter of the wireless control device  514 A—not shown) of the serial number for RFID device  510 A and/or an identification of the wireless control device  514 A (e.g., a serial number of the wireless control device  514 A) and/or the custom integration string of the RFID device  510 A. The wireless transmission of the serial number for wireless device  514 A and the serial number of the RFID device  510 A may be made via radio-frequency (RF) signals  210 , perhaps as part of a Wi-Fi protocol or a proprietary RF protocol (e.g. Clear Connect™). 
     The wireless transmission via RF signals  210  from the wireless control device  514 A may be directed to a wireless control device  506 A. In some configurations, the RF signals  210  from the wireless control device  514 A to the wireless control device  506 A may be conveyed via a wireless router  508  (e.g. a Wi-Fi router). Wireless control device  506 A may be configured to communicate with dimmer switches  502  and/or  504  via RF signals  210 . Upon receipt of the RF signals  210  from the wireless control device  514 A, the wireless control device  506 A may be configured to transmit one or more respective commands to the dimmer switches  502  and/or  504 . And the dimmer switches  502  and/or  504  may effectuate the respective commands by adjusting the respective intensity of the connected lighting loads  516  and  518  to levels that may correspond to the respective commands. In other words, the wireless control device  506 A may be configured to send respective commands to the dimmer switches  502  and/or  504  that may be preconfigured to correspond to the receipt of the RF signals  210  that include the serial numbers of the wireless control device  514 A and/or the RFID device  510 A (and/or the custom integration string of the RFID device of  510 A). 
     For example, a user may locate the RFID device  510 A at particular location in the user&#39;s home, perhaps on an end-table near the user&#39;s bed in the user&#39;s bedroom. At the time the user may wish to go to sleep, the user may place the wireless control device  514 A (e.g. the user&#39;s cell phone) into close proximity with the RFID device  510 A. The NFC signaling  208  that occurs between the RFID device  510 A and the wireless control device  514 A may trigger the communication from the wireless control device  514 A to the wireless control device  506 A. And the receipt by the wireless control device  506 A of the RF signals  210  that includes, for example, the serial numbers of the wireless control device  514 A and/or the RFID device  510 A (and/or the custom integration string of the RFID device  510 A) may be interpreted (e.g. according to a configuration) by the wireless control device  506 A to cause the dimmer switches  502  and/or  504  to lower the intensity of the lighting loads  516  and/or  518  (e.g., perhaps turning both lights off). 
       FIG. 5B  depicts a second example adjustment of a lighting load in a load control network  500 B with an interaction between a wireless device and a radio-frequency identification (RFID) device via near field communication (NFC). An RFID device  510 B, that may include a command script (not shown), may communicate via NFC signals  208  with a wireless control device  514 B. The RFID device&#39;s  510 B command script may be configured to send an identification of the RFID device  510 B, such as but not limited to a serial number of the RFID device  510 B, when the wireless control device  514 B comes into a proximity sufficient for NFC based communication. 
     The wireless control device  514 B (and/or a receiver of the wireless control device  514 B—not shown) may be configured to receive the serial number for RFID device  510 B. Upon receipt of the serial number for RFID device  510 B via the NFC signaling  208 , the wireless control device  514 A (and/or a controller of the wireless control device  514 B—not shown) may be configured to initiate a wireless transmission (e.g. via a transmitter of the wireless control device  514 B—not shown) of one or more respective commands to the dimmer switches  502  and/or  504 . The wireless transmission of the one or more respective commands to the dimmer switches  502  and/or  504  may be made via radio-frequency (RF) signals  210 , perhaps as part of a Wi-Fi protocol or a proprietary RF protocol (e.g. Clear Connect™). 
     The wireless transmission via RF signals  210  from the wireless control device  514 B may be directed to a wireless control device  506 B. In some configurations, the RF signals  210  from the wireless control device  514 B to the wireless control device  506 B may be conveyed via a wireless router  508  (e.g. a Wi-Fi router). Wireless control device  506 B may be configured to communicate with dimmer switches  502  and/or  504  via RF signals  210 . Upon receipt of the RF signals  210  from the wireless control device  514 B, the wireless control device  506 B may be configured to transmit RF signals  210  to the dimmer switches  502  and/or  504  that correspond to the one or more respective commands to the dimmer switches  502  and/or  504  sent by wireless control device  514 B. And the dimmer switches  502  and/or  504  may effectuate the respective commands by adjusting the respective intensity of the connected lighting loads  516  and  518  to levels that may correspond to the respective commands. In other words, the wireless control device  514 B may be configured to send respective commands to the dimmer switches  502  and/or  504  that may be preconfigured to correspond to the receipt by the wireless control device  514 B of the RF signals  208  that includes the serial number of the RFID device  510 B. 
     In some configurations of load control network  500 B, the wireless router  508  may be configured to, perhaps upon receipt of the RF signals  210  from the wireless control device  514 B, transmit RF signals  210  to the dimmer switches  502  and/or  504  that correspond to the one or more respective commands to the dimmer switches  502  and/or  504  sent by wireless control device  514 B. In such configurations, the commands to the dimmer switches  502  and/or  504  may not be forwarded by the wireless control device  506 B. 
     For example, a user may locate the RFID device  510 B at particular location in the user&#39;s home, perhaps near a door of the user&#39;s home. At the time the user may arrive home, the user may place the wireless control device  514 B (e.g. the user&#39;s cell phone) into close proximity with the RFID device  510 B. The NFC signaling  208  that occurs between the RFID device  510 B and the wireless control device  514 B may trigger (e.g. according to a configuration) the wireless control device  514 B to send the respective commands to the dimmer switches  502  and/or  504  via RF signals  210 . And the forwarding of the respective commands to the dimmer switches  502  and/or  504  via RF signals  210  from either of the wireless router  508  and/or the wireless control device  506 B may cause the dimmer switches  502  and/or  504  to increase the intensity of the lighting loads  516  and/or  518  (e.g., perhaps turning both lights to 100% intensity). 
       FIG. 5C  depicts a third example adjustment of a lighting load in a load control network  500 C with an interaction between a wireless device and a radio-frequency identification (RFID) device via near field communication (NFC). An RFID device  510 C, that may include a command script (not shown), may communicate via NFC signals  208  with a wireless control device  514 C. The RFID device&#39;s  510 C command script may be configured to receive an identification of the wireless control device  514 C, such as but not limited to a serial number of the wireless control device  514 C, when the wireless control device  514 C comes into a proximity sufficient for NFC based communication. In other words, the wireless control device  514 C (and/or a transmitter of the wireless control device  514 C—not shown) may be configured to transmit the serial number for the wireless control device  514 C via NFC signals  208  when the wireless control device  514 C enters into a proximity sufficient for NFC based communication with the RFID device  510 C (e.g., detection via NFC signals  208 ). 
     Upon receipt of the serial number for the wireless control device  514 C via the NFC signaling  208 , the RFID device&#39;s  510 C command script may be configured to initiate a transmission of one or more respective commands to the dimmer switches  502  and/or  504  to the wireless control device  514 C via NFC signals  208 . The wireless control device  514 C (and/or a receiver of the wireless control device  514 C—not shown) may receive the one or more respective commands to the dimmer switches  502  and/or  504  sent via the NFC signals  208 . 
     Upon receipt of the commands for the dimmer switches  502  and/or  504  via NFC signals  208 , the wireless control device  514 C may transmit RF signals  210  to the dimmer switches  502  and/or  504  that correspond to the respective commands for the dimmer switches  503  and/or  504  sent from the RFID device  510 C. The wireless transmission of the one or more respective commands to the dimmer switches  502  and/or  504  made via RF signals  210  may be part of a Wi-Fi protocol or a proprietary RF protocol (e.g. the Clear Connect™ protocol). 
     The wireless transmission via RF signals  210  from the wireless control device  514 C may be directed to a wireless control device  506 C. In some configurations, the RF signals  210  from the wireless control device  514 C to the wireless control device  506 C may be conveyed via a wireless router  508  (e.g. a Wi-Fi router). Wireless control device  506 C may be configured to communicate with dimmer switches  502  and/or  504  via RF signals  210 . Upon receipt of the RF signals  210  from the wireless control device  514 C, the wireless control device  506 C may be configured to transmit RF signals  210  to the dimmer switches  502  and/or  504  that correspond to the one or more respective commands to the dimmer switches  502  and/or  504  sent by wireless control device  514 C. And the dimmer switches  502  and/or  504  may effectuate the respective commands by adjusting the respective intensity of the connected lighting loads  516  and  518  to levels that may correspond to the respective commands. In other words, the RFID device  510 C may be configured to send respective commands to the dimmer switches  502  and/or  504  that may be preconfigured to correspond to the receipt by the RFID device  510 C of the RF signals  208  that include the serial number of the wireless control device  514 C. 
     In some configurations of load control network  500 C, the wireless router  508  may be configured to, perhaps upon receipt of the RF signals  210  from the wireless control device  514 C, transmit RF signals  210  to the dimmer switches  502  and/or  504  that correspond to the one or more respective commands to the dimmer switches  502  and/or  504  sent by wireless control device  514 C. In such configurations, the commands to the dimmer switches  502  and/or  504  may not be forwarded by the wireless control device  506 C. 
     For example, a user may locate the RFID device  510 C at particular location in the user&#39;s home, perhaps near an entrance to the user&#39;s family room. At the time the user may enter the family room, the user may place the wireless control device  514 C (e.g. the user&#39;s cell phone) into close proximity with the RFID device  510 C. The NFC signaling  208  that occurs between the RFID device  510 C and the wireless control device  514 C may trigger (e.g. according to a configuration) the RFID device  510 C to send the respective commands for the dimmer switches  502  and/or  504  to the wireless control device  514 C via RF signals  208 . The wireless control device  514 C may forward the commands for the dimmer switches  502  and/or  504  to the dimmer switches  502  and/or  504  via RF signals  210 . And the forwarding of the respective commands to the dimmer switches  502  and/or  504  via RF signals  210  from either of the wireless router  508  and/or the wireless control device  506 C may cause the dimmer switches  502  and/or  504  to change the intensity of the lighting loads  516  and/or  518  (e.g., perhaps turning lighting load  516  to 75% intensity and lighting load  518  to 50% intensity). 
       FIG. 6A  depicts an example of an environment for adjusting one or more electrical loads based on an interaction between a specific user&#39;s wireless control device and a radio-frequency identification (RFID) device. A user  112  may place an RFID device  644  in an area close to a door of user&#39;s  112  house  648 . The RFID device  644  may include a command script (not shown). The user  112  may install outdoor lights  640  and/or  642 . The user  112  may arrive home and wish to set a particular lighting scene in and around the house  648 . And the user  112  may have configured the user&#39;s wireless control device  646  (e.g. the user&#39;s smart cell phone) and/or the RFID device&#39;s  644  command script to provide at least one particular lighting scene. In such configurations, at least one of the user&#39;s  112  desired scenes may be effectuated by various load control devices (not shown) by the placement of the wireless control device  646  into close proximity with the RFID device  644  such that NFC signals  208  may be exchanged between the RFID device  644  and the wireless control device  646 . 
       FIG. 6B  depicts an example of adjusting one or more electrical loads based on an interaction between a specific user&#39;s wireless control device and a radio-frequency identification (RFID) device as presented in  FIG. 6A . As an effect of the placement of the wireless control device  646  into close proximity with the RFID device  644 , commands may be sent to dimmer switches (not shown) that control the intensity of the outdoor lights  640  and/or  642 . The commands to the dimmer switches may effectuate at least a part of the user&#39;s  112  desired lighting scene by setting the intensities of the outdoor lights  640  and/or  642  to 100%, for example. 
       FIG. 6C  depicts a further example of adjusting one or more electrical loads based on an interaction between a specific user&#39;s wireless control device and a radio-frequency identification (RFID) device as presented in  FIG. 6A . As a further effect of the placement of the wireless control device  646  into close proximity with the RFID device  644 , commands may be sent to dimmer switches and/or plug-in-device (PID) controllers (not shown) that control the intensity of indoor lights such as floor lamp  650 , ceiling lights  652 , table lamp  654 , and light sconce  656 . The commands to the dimmer switches and/or PID controllers may effectuate at least a part of the user&#39;s  112  desired lighting scene by setting the intensities of the floor lamp  650  and table lamp  654  to 100%, the intensities of the ceiling lights  652  to 50%, and the intensity of the light sconce  656  to 25%, for example. 
       FIG. 7A  illustrates an example of a transfer via near field communication (NFC) of a device database of an inoperable load control device to a replacement load control device. Load control devices, such as but not limited to dimmer switches  602  and  604 , may be configured to control the intensities of respectively connected lighting loads (not shown). Dimmer switches  602  and/or  604  may also be configured for near field communication (NFC) (e.g., via respective NFC modules—not shown). From time to time, a load control device may become inoperative for one or more of its configured operations. For example, a failed component inside the dimmer switch  602  may prevent the dimmer switch  602  from adjusting the intensity of connected lighting load as configured by a user. However, the inoperative dimmer switch  602  may still be capable of near field communication. As such, a wireless control device  606  may be placed into sufficient proximity to initiate near field communication (e.g., via an NFC module not shown) with the inoperative dimmer switch  602 . 
     The database of the inoperative dimmer switch  602  may be transferred from the inoperative dimmer switch  602  to the wireless control device  606  via NFC signals  208 . The database transferred from the inoperative dimmer switch  602  may be stored in a memory  608  of the wireless control device  606 . At some point in time, the inoperative dimmer switch  602  may be replaced with dimmer switch  602 A. Dimmer switch  602 A may be capable of being configured for, and may be capable of implementing, at least the same operations for which the inoperative dimmer switch  602  was configured. 
     The wireless control device  606  may be placed into sufficient proximity to transfer the database of the inoperative dimmer switch  602  to the new (or replacement) dimmer switch  602 A via NFC signals  208 . After receiving the database from the wireless control device  606 , the dimmer switch  602 A may perform at least the same functions as were performed by the inoperative dimmer switch  602 . Although a dimmer switch was used to describe this technique, the aforementioned technique may be useful for other types of load control devices, such as occupancy sensors, remote control devices, etc. 
       FIG. 7B  is a flowchart of an example technique to transfer via near field communication (NFC) a database of an inoperative load control device to a replacement load control device. At  7002 , at a starting point, a first device (e.g. a load control device) may become inoperative for one or more configured operations. At  7004 , the first device database may be uploaded via near field communication (e.g. to a wireless control device). At  7006 , the device database may be downloaded to a second device via near field communication. The second device may be a load control device that may be operative for the one or more configured operations for which the first device was configured. At  7008 , the download to the second device may be determined to be successful. At  7010 , if a successful download is determined, the technique may end and the second device may operate in the place of the first device. 
       FIG. 8  is a simplified block diagram of representative wireless control device  4000  (e.g. a smart cellular phone) that may be configured to implement any of the techniques described herein. The wireless device may include a controller  4014 . The controller  4014  may comprise a microcontroller, a programmable logic device (PLD), a processor, a microprocessor, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), and/or any suitable processing device or control circuit. The controller  4014  may be configured to implement one or more of the contemplated techniques described herein (e.g., initiate NFC communication). 
     The controller  4014  may also be coupled to a memory  4020  that may be used for storage of, among other things, access information for a wireless communication network, such as the SSID, security type, and/or key. The memory  4020  may also store programming instructions for communicating via a wireless communication link, or the like. The memory  4020  may be implemented as an external integrated circuit (IC) or as an internal circuit of the controller  4014 . The wireless device  4000  may further comprise a power supply  4022  that may generate a direct-current (DC) voltage V CC  for powering the controller  4014 , the memory  4020 , a wireless communication module  4030 , an NFC communication module  4040 , a user interface input-output module  4018 , and other elements of the wireless device shown and not shown. The power supply  4022  may be coupled to an alternating-current (AC) power source (not shown) via hot and neutral terminals H, N. Alternatively, the wireless device could comprise a battery for providing a battery voltage for powering the controller  4014 , the memory  4020 , a wireless communication module  4030 , an NFC communication module  4040 , a user interface input-output module  4018 , and other elements of the wireless device. 
     The wireless device  4000  may further include the wireless communication module  4030  for transmitting and receiving radio frequency (RF) signals to and from the wireless device  4000 . For example, the wireless communication module  4030  may be configured to communicate via a Wi-Fi communication link, a Wi-MAX communication link, a Clear Connect™ communication link, and/or a Bluetooth® communication link. When the wireless communication module  4030  comprises a Wi-Fi module, the controller  4014  may be operable to communicate via digital messages in Wi-Fi packets (e.g., Internet Protocol packets received via the Wi-Fi signals). The wireless communication module  4030  may include one or more RF transceivers and at least one antenna. The one or more RF transceivers may include one or more RF transmitters (e.g. transmitter circuits) and/or one or more RF receivers (e.g. receiver circuits). The controller  4014  may transmit messages from the wireless device  40000  via digital messages transmitted via the RF signals. For example, the controller  4014  may be used to transmit digital messages via wireless communication. 
     The wireless device  4000  may further include the NFC communication module  4040  for transmitting and receiving NFC protocol radio frequency (RF) signals to and from the wireless device  4000  and/or RFID devices, among other devices. For example, the NFC communication module  4040  may be configured to communicate via an NFC communication link. The NFC communication module  4040  may include one or more RF transceivers and at least one antenna. The one or more RF transceivers may include one or more RF transmitters (e.g. transmitter circuits) and/or one or more RF receivers (e.g. receiver circuits). The controller  4014  may transmit messages from the wireless device  4000  via the NFC protocol as transmitted via NFC/RF signals. For example, the controller  4014  may be used to transmit NFC messages via NFC-based wireless communication. 
     The wireless device  4000  may also include a user-interface input-output module  4018  for operating a character-based keyboard (hard-key or virtual) and/or another user/interface, such as a touch-screen interface. The controller  4014  may communicate with the user interface input-output module  4018  to receive user-input information (e.g. the access information for the wireless communication network). The controller  4014  may also communicate with the user-interface input-output module  4018  to allow the user to interact with and to control various functions that the controller may be configured to perform, such as but not limited to one or more of the contemplated techniques described herein to communicate information via NFC protocol communication. 
       FIG. 9  is a simplified block diagram of the dimmer switch  8000  (as an example load control device capable of NFC communication and to implement one or more of the techniques described herein). The dimmer switch  8000  may include a controllably conductive device  8010  coupled in series electrical connection between an AC power source  8002  and a lighting load  8004  for control of the power delivered to the lighting load. The controllably conductive device  8010  may comprise a relay or other switching device, or any suitable type of bidirectional semiconductor switch, such as, for example, a triac, a field-effect transistor (FET) in a rectifier bridge, or two FETs in anti-series connection. The controllably conductive device  8010  may include a control input coupled to a drive circuit  8012 . 
     The dimmer switch  8000  may further include a controller  8014  coupled to the drive circuit  8012  for rendering the controllably conductive device  8010  conductive or non-conductive to thus control the power delivered to the lighting load  8004 . The controller  8014  may include a microcontroller, a programmable logic device (PLD), a microprocessor, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or any suitable processing device or control circuit. A zero-crossing detector  8015  may determine the zero-crossings of the AC line voltage from the AC power supply  8002 . A zero-crossing may be the time at which the AC supply voltage transitions from positive to negative polarity, or from negative to positive polarity, at the beginning of each half-cycle. The controller  8014  may receive the zero-crossing information from the zero-crossing detector  8015  and may provide the control inputs to the drive circuit  8012  that may render the controllably conductive device  8010  conductive and non-conductive at predetermined times relative to the zero-crossing points of the AC waveform. 
     The controller  8014  may receive inputs from mechanical switches  8016  that may be mounted on a printed circuit board (not shown) of the dimmer switch  8000 , and may be arranged to be actuated by a toggle actuator (not shown) and an intensity adjustment actuator (not shown). The controller  8014  may also control light-emitting diodes  8018 , which may also be mounted on the printed circuit board. The light emitting diodes  8018  may be arranged to illuminate the status indicators (not shown) on the front surface of the dimmer switch  8000 , for example, through a light pipe structure (not shown). The controller  8014  may also be coupled to a memory  8020  for storage of unique identifiers (e.g., the MAC address and the IP address) of the dimmer switch  8000 , the SSID, the security type, and/or the security key of the wireless communication network, instructions for controlling the lighting load  8004 , programming instructions for communicating via a wireless communication link, or the like. The memory  8020  may be implemented as an external integrated circuit (IC) or as an internal circuit of the controller  8014 . A power supply  8022  may generate a direct-current (DC) voltage V CC  for powering the controller  8014 , the memory  8020 , and other low-voltage circuitry of the dimmer switch  8000 . 
     The dimmer switch  8000  may further include a wireless communication module  8030  for transmitting and receiving the RF signals to and from the wireless device  4000  and/or a wireless router. For example, the wireless communication module  8030  may be configured to communicate via a Wi-Fi communication link, a Wi-MAX communication link, a Clear Connect™ communication link, and/or a Bluetooth® communication link. When the wireless communication module  8030  comprises a Wi-Fi module, the controller  8014  may be operable to control the lighting load  8004  in response to received digital messages in Wi-Fi packets (e.g., Internet Protocol packets received via the Wi-Fi signals). The wireless communication module  8030  may comprise an RF transceiver and an antenna. The one or more RF transceivers may include one or more RF transmitters (e.g. transmitter circuits) and/or one or more RF receivers (e.g. receiver circuits). 
     The dimmer switch  8000  may further include an NFC communication module  8040  for transmitting and receiving NFC protocol radio frequency (RF) signals to and from the dimmer switch  8000  and/or or RFID devices, among other devices. For example, the NFC communication module  8040  may be configured to communicate via an NFC communication link. The NFC communication module  8040  may include one or more RF transceivers and at least one antenna. The one or more RF transceivers may include one or more RF transmitters (e.g. transmitter circuits) and/or one or more RF receivers (e.g. receiver circuits). The controller  8014  may transmit messages from the dimmer switch  8000  via the NFC protocol as transmitted via NFC/RF signals. For example, the controller  8014  may be used to transmit NFC messages via NFC-based wireless communication. 
     Examples of antennas for wall-mounted dimmer switches are described in greater detail in U.S. Pat. No. 5,982,103, issued Nov. 9, 1999, and U.S. Pat. No. 7,362,285, issued Apr. 22, 2008, both entitled COMPACT RADIO FREQUENCY TRANSMITTING AND RECEIVING ANTENNA AND CONTROL DEVICE EMPLOYING SAME, the entire disclosures of which are hereby incorporated by reference. 
     The controller  8014  may also transmit and receive messages to the wireless device  4000  via digital messages and/or NFC signals transmitted via the NFC/RF signals. For example, the controller  8014  of the dimmer switch  8000  may be used to transmit digital messages to the wireless device  4000  via wireless communication. The digital messages may include alerts and/or feedback and status information regarding the lighting load  8004 . The digital messages may also include error messages or indications as to whether the dimmer switch  8000  may be able to communicate via a wireless communication link or NFC/RF signal, for example. 
       FIG. 10  a simplified example block diagram  9000  of an input device like the remote control device  104  of  FIG. 1 . The example remote control device  9000  may include devices such as a controller  414 , a memory  420 , a wireless communication module  430 , and an NFC communication module  440 . One or more of the elements within these devices, one or more of the functions of these devices, and/or one or more of the interactions of and among these devices may be the same or similar as described with respect to the dimmer switch  8000  of  FIG. 9 . The remote control device  9000  may also include a battery power supply  450  that may provide electrical power to the one or more devices included in the remote control device  9000 , such as the controller  414 . 
     The example remote control device  9000  may also include buttons  452 , visual indicators  456 , and/or a battery  450 . The controller  414  of remote control device  9000  may be configured to receive commands input via the one or more buttons  452 . The one or more buttons  452  may include one or more soft buttons or one or more hard buttons (e.g. physical buttons or manual operators). For example, the controller  414  may interpret inputs via the one or more buttons  452  as user commands intended for one or more devices (e.g. a dimmer switch). Again by way of example, a user may contact one button of the one or more buttons  452  of remote control device  9000  to order the appropriate dimmer switch (e.g. dimmer switch  8000 ) to adjust the intensity of a lighting load  8004  to 50%, among many other configurable adjustments. The controller  414  of remote control device  9000  may interpret the signal from the one button of the one or more buttons  452  as a command to order the dimmer switch  8000  to perform the adjustment to 50%. 
     The controller  414  may communicate the command to the dimmer switch  8000  via one or more wireless signals sent via wireless communication module  430  and/or  440  (e.g. in a manner that is the same or similar to the functions described with respect to communication modules  8030  and/or  8040  as described with regard to  FIG. 9 ). The controller  414  of  5000  may be configured to control one or more visual indicators  456  to provide the user with one or more feedback or status indications (e.g. at least for a period of time). For example, one indicator of the one or more indicators  456  may indicate (e.g. for some period of time) that one or more buttons  452  may have been activated by a user (e.g. as interpreted by the controller  414 ). Also by way of example, one indicator of the one or more indicators  456  may indicate (e.g. for a period of time) that the dimmer switch  8000  has received the command from the controller  414  to perform an adjustment (e.g. as input by the user) of the lighting load  8004 . Also by way of example, one indicator of the one or more indicators  456  may indicate that that battery  450  is at a low level of charge. 
       FIG. 11  is a simplified example block diagram  9050  of a device like the occupancy sensor  180  of  FIG. 1 . The occupancy sensor  9050  may include one or more of the same or similar devices as those included and described with respect to the remote controller  9000  of  FIG. 10 . The one or more of the elements within these devices, one or more of the functions of these devices, and/or one or more of the interactions of and among these devices may be the same or similar as described with respect to  FIG. 10 . 
     The occupancy sensor  9050  may also include at least one sensor circuit  454 . The at least one sensor circuit  454  may detect the presence (or lack thereof) of people in a given area of senor effectiveness. The controller  414  of  9050  may be configured to receive a signal from the at least one sensor  454 , interpret the signal as indicating a presence or absence of people in the given area of sensor effectiveness (perhaps for a period of time), and/or send one or more commands to other devices based on the interpreted presence of people or lack thereof. For example, should the controller  414  of  9050  interpret the at least one sensor  454  to report the lack of presence in the given area of effectiveness (perhaps for some period of time, e.g. 60 seconds), the controller may send respective commands to one or more of the dimmer switches (for example) to lower the respective intensities of the lighting loads connected to such dimmer switches (e.g. shutoff all the lights when all people have left the room). Also by way of example, should the controller  414  of  9050  interpret the at least one sensor  454  to report a transition from a lack of any presence to the presence of at least one person in the given area of effectiveness, the controller may send respective commands to one or more of dimmer switches to increase the respective intensities of the lighting loads connected to such dimmer switches (e.g. turn at least some of the lights when at least one person enters the area of sensor effectiveness). The controller  414  of  9050  may communicate the command to the dimmer switches via one or more wireless signals sent via wireless communication module  430  (e.g. in a manner that is the same or similar to the functions described with respect to communication modules  430  as described with regard to  FIG. 10 ). 
     While the present application has been described with reference to the dimmer switches, RFID devices, occupancy sensors, remote control devices, and wireless control devices, the concepts of the contemplated devices and techniques could be applied to any control devices that are operable to communicate with each other, such as, for example, dimming ballasts for driving gas-discharge lamps; light-emitting diode (LED) drivers for driving LED light sources; screw-in luminaires including integral dimmer circuits and incandescent or halogen lamps; screw-in luminaires including integral ballast circuits and compact fluorescent lamps; screw-in luminaires including integral LED drivers and LED light sources; electronic switches, controllable circuit breakers, or other switching devices for turning appliances on and off; plug-in load control devices, controllable electrical receptacles, or controllable power strips for each controlling one or more plug-in loads; motor control units for controlling motor loads, such as ceiling fans or exhaust fans; drive units for controlling motorized window treatments or projection screens; motorized interior or exterior shutters; thermostats for a heating and/or cooling systems; temperature control devices for controlling setpoint temperatures of HVAC systems; air conditioners; compressors; electric baseboard heater controllers; controllable dampers; humidity control units; dehumidifiers; water heaters; pool pumps; televisions; computer monitors; audio systems or amplifiers; generators; electric chargers, such as electric vehicle chargers; an alternative energy controllers; occupancy sensors, vacancy sensors, daylight sensors, temperature sensors, humidity sensors, security sensors, proximity sensors, keypads, battery-powered remote controls, key fobs, cell phones, smart phones, tablets, personal digital assistants, personal computers, timeclocks, audio-visual controls, safety devices, and central control transmitters. 
     Additionally, the techniques described herein may be implemented as a set of computer-executable instructions stored on a computer-readable medium, such as a random-access or read-only memory for example. Such computer-executable instructions may be executed by a processor or microcontroller, such as a microprocessor, within the RFID devices, load control devise, or the wireless control devices, for example.
