An integrated, self-programming wireless control system that is interoperable with Cree’s offerings of fixtures, switches, and dimmers, SmartCast Technology allows for daylight harvesting and vacancy sensing without extra devices. Motion and ambient light sensors are embedded in each luminaire, eliminating the need for additional sensor layouts. Secure wireless communication is offered between luminaires and dimmers. A hand-held remote configuration tool allows for install fixtures and switches to be addressed using the manufacturer’s one-button setup procedure which automatically creates intelligent luminaire groupings and configurations.
