Abstract
A power over Ethernet (PoE) device system for a building including building devices connected together and to a PoE source via a network. The PoE source is configured to provide each of the building devices with PoE. A first building device of the building devices includes a communication subsystem circuit configured to receive the PoE from the PoE source via one of the building devices, power the communication subsystem circuit using the PoE received from the PoE source via the one of the building devices, and communicate with the PoE source and the building devices via the network. The first building device includes a functional subsystem circuit configured to power the functional subsystem circuit using power received from a permanent power source of the building and control an environmental condition of the building using the power received from the permanent power source of the building.
