Abstract
A state change device may be electrically connected to a switched receptacle, or to both the switched and unswitched receptacles, of an outlet. The state change device may generate a change of state signal when power is applied to, or removed from, the switched receptacle. The state change device may wirelessly communicate the signal. The state change device may include a load control circuit that may be configured to control the amount of power delivered to an electrical load that is electrically connected to the state change device. The state change device may receive commands directed to the load control circuit. The state change device may be deployed in a load control system and may operate as a control entity, such that the state change device may issue commands to one or more load control devices, responsive to the application or removal of power at the switched receptacle.
