Abstract
A system monitors operational status of a lighting element. A lighting fixture processor instructs a lighting element to illuminate at a predetermined time, receives sensed light level information from the light sensing element, and transmits a wireless message including information representing the sensed light level. A room controller can control some or all of these steps. A daylighting arrangement includes a room controller that instructs the lighting fixtures of a lighting group to illuminate their lighting elements at a predetermined time of day. Sensed light level information is obtained and wirelessly transmitted to the room controller, which determines an initial daylighting target for the lighting fixture group based on an average of the sensed light level information. The room controller instructs the lighting fixtures to illuminate their respective lighting elements in accordance with the initial daylighting target.
