Multimode commissioning switch powered by ground leakage current

A multimode switch, comprising:

• an actuator, configured to indicate a state responsive to a change in actuation;
• a wireless transceiver, configured to transmit and receive messages over a wireless network;
• a line voltage switch, coupled to a line voltage and to one or more associated devices;
• a switch controller, responsive to first messages received over said wireless network, configured to direct said line voltage switch to provide said line voltage to, and subsequently remove line voltage from, said one or more associated devices, and configured to receive first identifying information and functional group designation for said one or more associated devices in second messages over said wireless network, and configured to thereafter control said one or more associated devices according to said identifying information and functional group designation via transmission of third messages over said wireless network;
• and
• a ground leakage power supply, coupled to an AC hot line and to an earth ground, configured to generate a regulated voltage to power said wireless transceiver and said switch controller without requiring connection to an AC neutral line, while limiting ground leakage current to said earth ground to a prescribed leakage value.
