US Patent 9351381 System and method for controlling lighting

A controller for controlling a plurality of lighting devices configured for wireless communications in a facility includes a data communications interface communicating with at least one of the devices. The controller further includes a control module configured to provide a control signal to the data communications interface for communicating to a transceiver associated with the device and for turning off the device according to an algorithm wherein the control signal is provided based on a time of day and/or a sensed condition relating to use of the facility. The transceiver reports device data to the control module to quantify a reduction in power obtained by controlling the devices according to the algorithm.
