A system for monitoring and controlling electricity usage in a building includes a system control unit and an enhanced wiring device in wireless communication with the system control unit. The enhanced wiring device is hard-wired into the building electrical infrastructure, and is selected from the group consisting of an electrical outlet receptacle and an electrical power switch. The enhanced wiring device further includes a sensor for monitoring a stimulus parameter in a room of the building, a processor, at least one memory coupled to the processor, and program instructions stored on the at least one memory for execution by the processor to evaluate and communicate data from the sensor. The enhanced wiring device further includes an antenna for transmitting the sensor data to the system control unit, and a user interface connected to the system control unit adapted to configure and monitor data from the enhanced wiring device.
