Claim of US Patent No. 9,883,570

1. A lighting control system comprising:
a lighting control group, including a monitor lighting control device, a member lighting control device, and a luminaire;
wherein the monitor lighting control device comprises:
a wireless radio communication interface system configured for wireless communication over a wireless lighting control network
communication band, of control and systems operations information, during control network operation over the lighting control
network communication band;

a processor;
a memory accessible to the processor; and
programming in the memory which configures the processor to:
receive via the wireless radio communication interface a state change event message that includes a payload specifying:
(i) a state change event of an occupancy sensor, an audio sensor, a daylight sensor, or a switch to turn lighting on/off,
dim up/down, or set scene;

(ii) an identifier of the member lighting control device that detected the state change event; and
(iii) a lighting control group identifier of the lighting control group that includes the member lighting control device and
the monitor lighting control device;

in response to receiving the state change event message, transmit via the wireless radio communication interface an acknowledgement
of receipt of the state change event message to the member lighting control device;

extract and save the payload from the state change event message and generate a state change multicast message that includes
the state change event of the extracted payload; and

transmit via the wireless radio communication interface the generated state change multicast message to members of the lighting
control group.
