Abstract

A wireless switching apparatus is provided for three-way switching at least one energy load with an AC power source. The apparatus comprises a relay controlled by a controller. The controller is also connected to both a toggle and a wireless transceiver. A remote wireless transceiver unit is in communication with the wireless transceiver. The controller operates the relay for making and breaking electrical continuity between the energy load and an AC power source in response to a change in the state of either toggle or wireless signals received from the remote wireless transmitting unit. Control of the energy load using a combined system comprising an energy monitoring device operatively coupled to the apparatus is also provided. Methods are provided for retrofitting conventional receptacles and switches with the wireless switching apparatus.
