Abstract: A building system for a building includes an environmental controller including a controller radio. The environmental controller is configured to communicate a wake-up message. The building system includes an environmental sensor including a wake-up radio and a main radio. The environmental sensor is configured to operate the main radio in a low power state. The environmental sensor is configured to receive the wake-up message from the controller radio via the wake-up radio. The environmental sensor is configured to operate the main radio in a high power state in response to a reception of the wake-up message via the wake-up radio. The environmental sensor is configured to communicate sensor data of the environmental sensor to the controller radio via the main radio in response to the main radio operating in the high power state.

Abstract: A thermostat gateway device includes one or more circuits configured to receive a control input from a user device or from a sensor device via a first frequency band of a local wireless network, generate a control signal for the HVAC equipment using the control input, and provide the control signal to the HVAC equipment via a second frequency band of the local wireless network to affect operation of the HVAC equipment.

Abstract: A system for reducing power consumption in a wireless network includes a station (e.g., Wi-Fi sensor) and an access point in wireless communication with the station. The station has at least a low-power sleep mode and an active mode. The system can be configured to assign a static Internet Protocol (IP) address to the station and disable re-negotiation of an encryption key while the station is in sleep mode. The system can further be configured to force the station to communicate via 802.11g and to transmit data to a proxy service while in active mode before returning to sleep mode upon receiving a response from the proxy service. Further, an association timeout period associated with the station can be configured to be at least twice as long as a wake-up period associated with the station.

Abstract: A method for detecting an event in or around a building. The method includes recording a baseline signal characteristic that characterizes a wireless signal transmitted between devices in or around the building during a baseline time period and recording a second signal characteristic that characterizes the wireless signal during a second time period after the baseline time period. An event in or around the building is detected in response to a determination that the second signal characteristic is abnormal relative to the baseline signal characteristic, the event degrading the wireless signal during the second time period. An alarm is triggered in response to detecting the event.

Abstract: The present disclosure relates to a building network system for a building. The system includes network devices forming a network for the building. Each of the network devices include a communications processing circuit including an access point configured to communicate with any of the network devices to form the network, and a second processing circuit removably communicably connected to the communications processing circuit. The communications processing circuit and the second processing circuit are configured to operate independently of each other. The access point is a wireless radio configured to wirelessly communicate with the access points of any of the network devices.
