1. A wireless lighting control system comprising:
- a plurality of lighting control subsystems, each of the plurality of lighting control subsystems comprising;
a ballast coupled to a lighting device;
a power supply configured to supply power to the ballast; and
a wireless node coupled to the ballast, the wireless node receiving power from the ballast and configured to receive lighting control instructions that when processed control the lighting device by varying the supply of power supplied by the ballast to the lighting device.

Abstract
Autonomous lighting subsystems include ballast-powered wireless nodes for receiving control signals to control lighting devices. Autonomous lighting subsystems may be networked with other autonomous lighting subsystems to control various building-devices, including but not limited to lighting ballasts, occupancy sensors, daylight harvesters, and building automation control devices.

13. A method for networking an autonomous lighting subsystem comprising:
-
autonomously powering at least one wireless node within a lighting subsystem, the at least one wireless node being coupled to a ballast and receiving current from the ballast; receiving a unique digital command signal via a communications interface of the at least one wireless node, the unique digital command signal being addressable to the at least one wireless node within the lighting subsystem; deriving a lighting control instruction from the unique digital command signal, the lighting control instruction providing an instruction that when executed controls the power delivered by the ballast to a lighting device coupled to the ballast; and processing the lighting control instruction to control the power delivered by the ballast to the lighting device coupled to the ballast. - View Dependent Claims (14, 15, 16, 17)

18. A method for networking an autonomous lighting subsystem comprising:
-
autonomously powering at least one wireless node within a lighting subsystem, the at least one wireless node being coupled to a ballast and receiving current from the ballast; receiving by the at least one wireless node an input signal from an ancillary control device; transmitting via the at least one wireless node at least a portion of the input signal to a remote processing device; receiving from the remote processing device a unique digital command signal derived from the at least a portion of the input signal, the unique digital command signal being addressable to the at least one wireless node within the lighting subsystem; deriving a lighting control instruction from the unique digital command signal, the lighting control instruction providing an instruction that when executed controls the power delivered by the ballast to a lighting device coupled to the ballast; and processing the lighting control instruction to control the power delivered by the ballast to the lighting device coupled to the ballast.
