S200 includes step S210 of the smart device <NUM> displaying collected sensor data, and step S220 of instructing the sensor <NUM> to dynamically collect new data. At step S230 the smart device <NUM> may display the dynamically collected data. This process enables dynamically illustrating trends in the sensed data. According to an embodiment the sensor <NUM> is configured to sense a ride characteristic. The ride characteristic may be ride quality.

The smart device <NUM> is capable of instructing the sensor <NUM> to adjust sensitivity levels. Thus various levels of sensed data can be obtained and analyzed to enable calibrating the sensor <NUM> for results in a particular bandwidth of needed data. According to an embodiment the smart device <NUM> provides a scheduling calendar for scheduling elevator diagnostics based on the illustrated trends. That is, an elevator mechanic <NUM> with the smart device <NUM> can review data and determine therefrom whether to seek a full diagnostic of the elevator system.

According to an embodiment the smart device <NUM> may be a mobile phone. In addition the smart device <NUM> may communicates with the sensor <NUM> over a wireless ad hoc network <NUM>. Alternatively the system <NUM> may include a controller <NUM> for operatively communicating with the sensor <NUM> over a local area network <NUM> and communicating with the smart device <NUM> over a personal area network <NUM>. According to an embodiment the system <NUM> may comprise a telecommunications beacon <NUM> for effecting communications with the smart device <NUM> over the personal area network <NUM>. In an embodiment the controller <NUM> is a building management system (BMS).

Disclosed above is a system with which an elevator mechanic is provided with access to view collected sensor data and/or activate a sensor to collect new data and schedule elevator diagnostics. The disclosed embodiments may provide for controlling sensor calibration levels to more accurately detect ride quality details, to provide for a better condition elevator service, to provide an improved service efficiency, and to increase user experience.

As used herein, "smart devices" may contain one or more processors capable of communication using with other such devices by applying wired and/or wireless telecommunication protocols. Non-limiting examples of a smart device include a mobile phone, personal data assistant (PDA), tablet, watch, wearable or other processor-based devices. Protocols applied by smart devices may include local area network (LAN) protocols and/or a private area network (PAN) protocols. LAN protocols may apply Wi-Fi technology, which is a technology based on the Section <NUM> standards from the Institute of Electrical and Electronics Engineers, or IEEE. PAN protocols include, for example, Bluetooth Low Energy (BTLE), which is a wireless technology standard designed and marketed by the Bluetooth Special Interest Group (SIG) for exchanging data over short distances using short-wavelength radio waves. PAN protocols may also include Zigbee, a technology based on Section <NUM>. <NUM> protocols from the Institute of Electrical and Electronics Engineers (IEEE). More specifically, Zigbee represents a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios for low-power low-bandwidth needs, and is best suited for small scale projects using wireless connections. Wireless protocols may further include short range communication (SRC) protocols, which may be utilized with radio-frequency identification (RFID) technology. RFID may be used for communicating with an integrated chip (IC) on an RFID smartcard. Wireless protocols may further include long range, low powered wide area network (LoRa and LPWAN) protocols that enable low data rate communications to be made over long distances by sensors and actuators for machine-to-machine (M2M) and Internet of Things (IoT) applications.
