Abstract
A system for controlling remotely located electrically-powered systems in an electrical network includes a first transceiver. The first transceiver has an identifier in memory and wirelessly communicates bidirectionally with a control center via a plurality of additional wireless birdirectional transceivers. At least one of the plurality of additional wireless bidirectional transceivers is a site controller coupled to a wide area network. At least another of the additional wireless bidirectional transceivers is coupled to a meter. A microcontroller is coupled to the first transceiver and to a remotely located electrically-powered system. The microcontroller controls operation of the electrically-powered device from at least a state of powered on to a state of powered off when a signal associated with actuating the power state of the remotely located electrically-powered system is received. A keypad containing user selectable buttons is coupled to the microcontroller for receiving user input.
