REDUCING ENERGY CONSUMPTION OF SMART SOCKETS WITH PLUG DETECTION SENSORS

A system comprising smart sockets each having a plug receptacle, a plug detection sensor; and a socket controller configured to switch power off or on to the plug receptacle; and a supervisor configured to detect a change in a plug state, in response to identifying a change from the plug absent state to the plug present state, the supervisor is configured to send a control signal to a smart socket of one or more of the smart sockets that causes the corresponding socket controller to switch on power to the corresponding plug receptacle of the smart socket; and in response to identifying a change from the plug present state to the plug absent state, the supervisor sends a control signal to the smart socket of one or more of the smart sockets that causes the corresponding socket controller to switch off power to the corresponding plug receptacle.
