     DETAILED DESCRIPTION OF THE INVENTION 
       [0026]    Disclosed are method and systems for automatically adjusting product or service usage (e.g., building utilities) for maximum efficiently or effectiveness by using forecasted and reported environmental conditions (such as weather conditions or utility rate schedules and municipal restrictions) available over a wide area network, including without limitation the Internet or a direct data feed for each location defined by the user (Local Data). 
         [0027]    An exemplary embodiment described herein describes a system and methods using the present invention for the optimization of water use in landscape irrigation Local Data. 
         [0028]      FIG. 1  shows the major components of the present invention. The system consists of User Input or preferences  101 , Third Party Data  102 , the Internet  103 , a server  104 , a wireless carrier or network  105 , a receiver and switching device  106  and irrigation valves  107 . 
         [0029]    The user input includes a desired watering schedule or periodic water budget for each irrigation site administered by the system. Users also define what Local Data will trigger a modification of the schedule or budget described above (a “Modification Event”). Users will further define the types of modifications that will be triggered by certain Modification Events depending on particular data (“Modification Algorithms”). Cumulatively these schedules, preferences and Modification Algorithms will be referred to as the “User Data.” 
         [0030]    Third party data consists of weather data, municipal data (including rate schedules and individual usage data) and any other data available to the system over the internet. Cumulatively this data will be referred to as “Third Party Data.” 
         [0031]    The system uses the Internet to collect User Data and Local Data. Data can be collected via an XML feed like the one the National Weather Service is currently operating, by screen scraping, data mining, or other data extraction techniques or by using a wireless “DataCasting” network like that of Ambient Devices. The invention transmits this data to a fourth component of the system, an Irrigation Server. The Irrigation Server stores all of the User Data and the Local Data as well as processing modifications to the schedules and budgets. 
         [0032]    The present invention uses a wireless carrier to transmit and potentially collect data. Different exemplary embodiments of the present invention may used, any type of wireless carrier including but not limited to: one way paging, two-way paging, Cellular Digital Packet Data (CDPD), Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), or datacasting network that the system uses to transmit irrigation instructions to the sites for irrigation. 
         [0033]    The Switch is the component that executes the irrigation schedule as defined by the user and modified by the system. It is capable of receiving signals from the wireless carrier. It reads these signals and uses them to open and close valves for each irrigation zone defined up by the User Data. One potential feature of the Switch is a limited memory for storage of a “default” watering schedule, which would run in the event the irrigation switch did not receive an instruction from the Irrigation Server. 
         [0034]    The irrigation valves themselves will open and close according to the instructions send to the switch from the server. 
       Operation of the Invention. 
       [0035]      FIG. 2  shows the process beginning when a user logs on to the system and enters a desired irrigation schedule or water budget via an internet connection for a particular location. That location is identified to a particular weather zone. A weather zone is a defined area, for which the system can access Local Data, which pertains only to that zone. For example, the Dallas-Fort Worth metro area may be reported as a single weather area, but the user can identify a weather zone that is much smaller, like a particular neighborhood or suburb as long as there is reliable Third Party Data for such zone. A user irrigating multiple such locations would be put each location into a group according to the weather zones as described above. So if a user has five sites with two or more in a single weather zone such user could defined common preferences and Modification Algorithms for all sites in that zone (like a rain shutdown) even if other components of the User Data differ from site to sit. The user also enters Modification Algorithms. For example, the user may specify a two hour delay in the irrigation schedule if rain is forecast with an 80% probability or greater in any single weather zone. Thus a user is able to predicate certain modification to a programmed irrigation schedule based on any Modification Event identified by such user. 
         [0036]    The user&#39;s site locations, weather zones and preference data are stored on an irrigation server (“Server”). Shortly before an irrigation schedule is programmed to begin the system will check the Local Data. The Local Data is analyzed against the User Data to check for a Modification Event. If there is none, the system transmits the instructions to the Switch, which opens and closes the irrigation valves in the order and for the duration stipulated by the User Data. If there is a Modification Event the system uses the Modification Algorithm to determine what action is taken. If it is a delay the system waits for the delay period and then returns to point where it checks Local Data before sending irrigation instructions. If the action demanded by the Modification Event is a modification, like a reduction in the amount of time each valve is opened, the system modifies the schedule per the Modification Algorithm and then sends the modified instructions to the Switch. 
         [0037]    The invention has several advantages over the current state of the art. First is its extensive use of third party data. Many systems use individual weather stations, which are expensive and require installation and maintenance. The third party data is widely available from public and private web site. It can be used at no cost in many cases or for a relatively nominal fee. 
         [0038]    Another important feature is ease of use. Most irrigation controllers are manually set up and adjusted using an analog switch or by manually entering a schedule into a static piece of equipment. Consequently most irrigation systems are adjusted only twice per year. The initial set up of the invention can be done via telephone or internet portal. These options permit the use of an interactive menu as well as email notices to the user. The internet portal gives the system the advantage of a graphic user interface that is easy to navigate, learn use and modify. Furthermore, if a user enters preferences that so permit, the system will self adjust not only for day to day weather variations but for seasonal changes (including local time changes) as well. Thus, while a prudent user will evaluate the effectiveness of the systems on a periodic ongoing basis, once programmed, the system will address irrigation needs indefinitely. 
         [0039]    The invention is also more efficient in its use of hardware than much of the prior art. Most irrigation systems use an irrigation controller that holds the irrigation schedule in a local memory at the irrigation site. This adds to the cost and the complexity of the irrigation controller. Large installations with multiple controllers must each be individually programmed and maintained or have the scheduled updated via a master controller. By contrast the Switch requires almost no memory or local programming controls. It is simply a switching device enabled by a wireless connection. Other than a backup program all of the primary instructions are stored and modified in the irrigation server, which delivers instructions to the Switch in “real time” as the schedule is programmed to execute. The only hardware the invention requires is a server and a wireless connection capable or transmitting instructions to the switch. Each irrigation site will require only an irrigation switch, which is enabled with a wireless receiver. 
       Alternative Embodiments 
       [0040]    The present invention is a process that uses data available over a wide area network like the Internet and uses this data to permit a user to program the system to turn any product or service on or off, or modify a usage schedule therefore, by selecting an data event to trigger such change and identifying a source for the data available via the internet from third party data providers. 
       Alternative Embodiment 1 
       [0041]    Another embodiment of the present invention is to use third party data available over the internet to shut down or modify usage of certain systems that consume utilities when the rates for such utilities reach predefined levels or when the provider of such utilities is experiencing a spike in demand that threatens a “brown out” or other event as defined by the user. 
         [0042]      FIG. 3  shows the system would function in a manner very similar to the irrigation product described above except that instead of irrigation schedules being modified using third party weather data, it would modify power (or other utility usage) can be using utility data. The user enters its preferences over the Internet defining what data will be used as Local Data and what constitutes a Modification Event. The system may but need not control the day to day scheduled usage for such utility. In the case of a Modification Event the system can shut down or modify usage of the utility. 
         [0043]    For example, the system can be used to optimize electrical power usage by running certain processes when rates are lowest and shutting down, or modifying usage when rates are highest. It could adjust the thermostat several times per day based on utility rates and forecasted usage of the building. It could cool a building to below the optimal temperature when rates are low in the morning, and then reset the thermostat to slightly higher levels thought the day as rates climb. When rates drop or there is no forecasted use the system will set the temperature appropriate for those conditions. The system can interact with local controls or data to facilitate such optimization. In some cases, the system may be able to operate the building controls from the server directly over the internet without need of a wireless network. However, the wireless enabled switch will ensure that operation is possible without an internet connection. 
         [0044]    This is a substantial improvement upon the prior art. Many building controls can be set for certain schedules, which can be programmed based on rates, but the present invention automates this process. Furthermore, as rates change or building conditions change the present invention can react to such changes based on the User Data. 
       Alternative Embodiment 2 
       [0045]    Yet another embodiment is to use the present invention to read utility rate data as described above and use such data to predict a user&#39;s utility expense or usage based on such user&#39;s programmed utility use. Such embodiment could also use forecasted Local Data as described in the preferred embodiment to forecast modifications to the programmed utility use and predict usage using such modifications as part of the calculation. 
       Alternative Embodiment 3 
       [0046]    Additionally, another alternative embodiment for the present invention to adjust lighting, temperature or other building controls according user preferences by reading third party sunrise, sunset, forecasted temperature, precipitation or other weather data available over the internet via third party data providers. 
       Alternative Embodiment 4 
       [0047]    Additionally, another alternative embodiment for the present invention to use the process described in the preferred embodiment to create or modify feeding, housing or activity schedules for livestock. 
         [0048]    Additionally, another alternative embodiment for the present invention to use the process described in the preferred embodiment to create or modify supply or inventory programs for businesses. 
         [0049]    Additionally, another alternative embodiment for the present invention to use the process described in the preferred embodiment to create or modify staffing schedules for businesses. 
         [0050]    Additionally, another alternative embodiment for the present invention to use the process described in the preferred embodiment to create or modify schedules for utility usage, inventory, staffing or logistics.
