Abstract
Systems and methods are provided for controlling light in a 3-way light circuit, where at least one of the switches in a 3-way light circuit includes an occupancy sensor and the on/off state of the load in the 3-way circuit is determined based on the voltage output of circuits configured to provide power to the 3-way light circuit.
