A device and method for controlling a host apparatus (300) through a wireless link with a personal controller (10). The device includes a wireless communications module (202) configured to communicate with personal controller (10) via a peer-to-peer communications standard. The device connects to host apparatus (300) via a plug and receptacle interface (206) which includes power and signal pins. The device simulates an actuation signal using a reed relay (216) to cause host apparatus (300) to perform a function.

A light switch plate includes a wireless transmitter for transmitting control signals to a smart light assembly. The light switch plate is placed over a conventional light switch and prevents a user from further manipulating the conventional light switch. The light switch plate includes a further switch which a user can manipulate to cause the transmitter to transmit control signals to turn on or turn off a light of the smart light assembly.

A load control system may be provided including control devices and a system controller. The system controller may be configured to broadcast a service set identifier (SSID) and provide a wireless network connection to a network device. The system controller may provide a web page to the network device, wherein the web page may include an indication of target system controllers. The target system controllers may be used for configuring (e.g., associating) the control devices. The system controller may receive an indication of a target system controller selected to associate the control devices. The system controller may determine an address and port number of the target system controller identified by the network device. The system controller may provide, to the network device, the web page from the target system controller while the network device is connected to the system controller via the wireless network connection.

A sensor in a building HVAC system includes a transducer configured to measure a variable in the building HVAC system and to generate a sensor reading indicating a value of the measured variable. The sensor includes a communications interface configured to provide the sensor reading to a control device in the building HVAC system and a near field communication (NFC) circuit separate from the communications interface. The NFC circuit is configured to facilitate bidirectional NFC data communications between the sensor and a mobile device. The sensor includes a processing circuit having a processor and memory. The processing circuit is configured to wirelessly transmit data stored in the memory of the sensor to the mobile device via the NFC circuit, wirelessly receive data from the mobile device via the NFC circuit, and store the data received from the mobile device in the memory of the sensor.
