A monitor lighting control device receives a state change event message that includes a payload specifying: (i) a state change event of an occupancy, audio, or daylight sensor, or a switch to turn lighting on/off, dim up/down, set scene or the like; (ii) an identifier of a member lighting control device that detected the state change event; and (iii) a lighting control group identifier of a lighting control group that includes the member lighting control device and the monitor lighting control device. The monitor lighting control device transmits an acknowledgement of receipt of the state change event message to the member lighting control device. The monitor lighting control device generates a state change multicast message that includes the state change event of the payload. Also, the monitor lighting control device transmits the generated state change multicast message to the lighting control group.
