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.
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'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'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.
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.
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).
At the time of manufacture, the manufacturer may not have sufficient information from which to provide the multi-button remote control selector switch devices 1002A-1002D with a specific device configuration. For example, an end-user who purchases (e.g. at some point in time) the respective load control devices 1002A-1002D, 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 1002A-1002D that may be purchased by end-users. Thus, at the time of manufacture, the load control devices 1002A-1002D 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 1002A-1002D 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 1002A-1002D. For example, the general type of the load control devices 1002A-1002D may be a multi-button remote control device, for example. By providing at least an initial database for the load control devices 1002A-1002D at a time proximate to manufacture, the manufacturer may provide basic operational database parameters for the respective load control devices 1002A-1002D. 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 1002A-1002D by an end-user. Also, providing the initial database may permit the manufacturer to determine the respective load control devices' 1002A-1002D 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 1002A-1002D 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 1002A-1002D via NFC signals 208.
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
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.
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'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'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's 320 command script. Appropriate authority may be determined by the RFID device 320 (and/or the RFID device'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'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'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's 320 command script. For example, the controller of the two-button remote control selector switch 302 and/or the RFID device'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'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'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'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'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'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.
The wireless control device 514A (and/or a receiver of the wireless control device 514A—not shown) may be configured to receive the serial number for RFID device 510A and/or the custom integration string for RFID device 510A. Upon receipt of the serial number and/or the custom integration string for RFID device 510A via the NFC signaling 208, the wireless control device 514A (and/or a controller of the wireless control device 514A—not shown) may be configured to initiate a wireless transmission (e.g. via a transmitter of the wireless control device 514A—not shown) of the serial number for RFID device 510A and/or an identification of the wireless control device 514A (e.g., a serial number of the wireless control device 514A) and/or the custom integration string of the RFID device 510A. The wireless transmission of the serial number for wireless device 514A and the serial number of the RFID device 510A 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 514A may be directed to a wireless control device 506A. In some configurations, the RF signals 210 from the wireless control device 514A to the wireless control device 506A may be conveyed via a wireless router 508 (e.g. a Wi-Fi router). Wireless control device 506A 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 514A, the wireless control device 506A 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 506A 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 514A and/or the RFID device 510A (and/or the custom integration string of the RFID device of 510A).
For example, a user may locate the RFID device 510A at particular location in the user's home, perhaps on an end-table near the user's bed in the user's bedroom. At the time the user may wish to go to sleep, the user may place the wireless control device 514A (e.g. the user's cell phone) into close proximity with the RFID device 510A. The NFC signaling 208 that occurs between the RFID device 510A and the wireless control device 514A may trigger the communication from the wireless control device 514A to the wireless control device 506A. And the receipt by the wireless control device 506A of the RF signals 210 that includes, for example, the serial numbers of the wireless control device 514A and/or the RFID device 510A (and/or the custom integration string of the RFID device 510A) may be interpreted (e.g. according to a configuration) by the wireless control device 506A 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).
The wireless control device 514B (and/or a receiver of the wireless control device 514B—not shown) may be configured to receive the serial number for RFID device 510B. Upon receipt of the serial number for RFID device 510B via the NFC signaling 208, the wireless control device 514A (and/or a controller of the wireless control device 514B—not shown) may be configured to initiate a wireless transmission (e.g. via a transmitter of the wireless control device 514B—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 514B may be directed to a wireless control device 506B. In some configurations, the RF signals 210 from the wireless control device 514B to the wireless control device 506B may be conveyed via a wireless router 508 (e.g. a Wi-Fi router). Wireless control device 506B 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 514B, the wireless control device 506B 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 514B. 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 514B 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 514B of the RF signals 208 that includes the serial number of the RFID device 510B.
In some configurations of load control network 500B, the wireless router 508 may be configured to, perhaps upon receipt of the RF signals 210 from the wireless control device 514B, 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 514B. In such configurations, the commands to the dimmer switches 502 and/or 504 may not be forwarded by the wireless control device 506B.
For example, a user may locate the RFID device 510B at particular location in the user's home, perhaps near a door of the user's home. At the time the user may arrive home, the user may place the wireless control device 514B (e.g. the user's cell phone) into close proximity with the RFID device 510B. The NFC signaling 208 that occurs between the RFID device 510B and the wireless control device 514B may trigger (e.g. according to a configuration) the wireless control device 514B 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 506B 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).
Upon receipt of the serial number for the wireless control device 514C via the NFC signaling 208, the RFID device's 510C 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 514C via NFC signals 208. The wireless control device 514C (and/or a receiver of the wireless control device 514C—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 514C 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 510C. 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 514C may be directed to a wireless control device 506C. In some configurations, the RF signals 210 from the wireless control device 514C to the wireless control device 506C may be conveyed via a wireless router 508 (e.g. a Wi-Fi router). Wireless control device 506C 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 514C, the wireless control device 506C 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 514C. 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 510C 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 510C of the RF signals 208 that include the serial number of the wireless control device 514C.
In some configurations of load control network 500C, the wireless router 508 may be configured to, perhaps upon receipt of the RF signals 210 from the wireless control device 514C, 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 514C. In such configurations, the commands to the dimmer switches 502 and/or 504 may not be forwarded by the wireless control device 506C.
For example, a user may locate the RFID device 510C at particular location in the user's home, perhaps near an entrance to the user's family room. At the time the user may enter the family room, the user may place the wireless control device 514C (e.g. the user's cell phone) into close proximity with the RFID device 510C. The NFC signaling 208 that occurs between the RFID device 510C and the wireless control device 514C may trigger (e.g. according to a configuration) the RFID device 510C to send the respective commands for the dimmer switches 502 and/or 504 to the wireless control device 514C via RF signals 208. The wireless control device 514C 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 506C 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).
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 602A. Dimmer switch 602A 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 602A via NFC signals 208. After receiving the database from the wireless control device 606, the dimmer switch 602A 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.

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.
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 VCC 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.
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
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
