Claim of US Patent No. 11,116,064


1. A method of controlling a lighting control system comprising:transmitting a communication signal from a first light control module to a second light control module of a plurality of light control modules, each light control module configured to cause a transmission of a quantity of electrical energy to one of a plurality of lighting circuits of one of a plurality of light fixtures electrically connected to a respective light control module;
determining a time of day;
detecting occupancy at each light control module in the plurality of light control modules;
determining a last light control module to detect occupancy; and
after a specified time of day and in response to a negative occupancy detection at each light control module of the plurality of light control modules, changing a flow of electricity to at least one of the lighting circuits to turn off a respective light fixture and, in response to detecting a positive occupancy at the last light control module, turn on the respective light fixture connected to the last light control module of the plurality of light control modules.
