Abstract: A system for a building includes a device includes a first and second connector. The device also includes a switch having a first, a second, and a third port. The first connector is coupled to the first port of the switch and the second connector is coupled to the second port of the switch. The device also includes a controller that causes the first port to be coupled to the second port when the switch is not involved in communication between the first and second ports and the third port. When the switch is involved in communication between the first and second ports, the first port and the second port are each coupled to the third port, and the third port is coupled to the controller.

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 device for use in a building management system (BMS) includes a base hardware component that provides communication between the equipment and a first network associated with the BMS. The base hardware component includes a processor and a memory. The device further includes a modular hardware component connected to the base hardware component and a modular software component stored in the memory that recognizes the modular hardware component connected to the base hardware component and provides communication between the equipment and a second network using the modular hardware component. The processor executes a control application to control operation of the equipment based in part on data received from the equipment and data received from at least one of the first network and the second network.
