Abstract: An element of a building automation system is described that comprises a multifunctional system integrator contained in a standard receptacle gang box for outlets. The system provides enhanced safety and security, power metering, power control, and home diagnostics. The module can include an AC to DC power supply, a bidirectional solid state dimmer switch, a microprocessor, a communications subsystem and sensors that are controlled by the internal microprocessor. The module includes a user interface for programming and control. The apparatus replaces existing outlet receptacles with a familiar flush but elegantly updated and seamlessly integrated faceplate.
