Claim of US Patent No. 10,694,610

1. An apparatus for use in a load control system for controlling an amount of power delivered to at least one lighting load, the apparatus comprising:a plug that comprises a pair of blades configured to be inserted into a receptacle of an electrical outlet, the receptacle comprising a switched receptacle;
a sensing circuit that detects whether power is present at the switched receptacle;
a controller that is communicatively coupled to the sensing circuit and configured to:
receive an indication from the sensing circuit that power is not present at the switched receptacle;
in response to receiving the indication, determine whether power has been removed or a line disturbance has occurred;
in response to determining that power has been removed, generate a signal that is indicative of a change of state of power being supplied at the switched receptacle; and
in response to determining that a line disturbance has occurred, do not generate the signal; and
a wireless communication circuit coupled to the controller,
wherein the controller causes the wireless communication circuit to transmit the signal to one or more associated devices.
