Abstract

Claims (14)

1. A system for controlling remotely located electrically-powered systems in an electrical network, the system comprising:

a first transceiver located at a customer premise and coupled by an interface to a meter and further having an identifier storable in a memory coupled to the first transceiver, the first transceiver being configured to wirelessly communicate bidirectionally according to the identifier with a control center via a plurality of additional wireless bidirectional transceivers, at least one of the additional wireless bidirectional transceivers being a site controller coupled to a wide area network and at least another of the additional wireless bidirectional transceivers also being coupled by an interface to a meter;

a microcontroller coupled to the first transceiver and to a remotely located electrically-powered system and operable to control the operation of the electrically-powered system from at least a state of powered on to a state of powered off when the microcontroller receives a signal associated with actuating the power state of the remotely located electrically-powered system; and

a keypad containing user selectable buttons electrically coupled to the microcontroller for receiving user input.

2. The system of claim 1 , wherein the electrically-powered system is an HVAC system.

3. The system of claim 1 , wherein the electrically-powered system is a lighting system.

4. A device located at each of a plurality of customer premises in an electrical power distribution system for controlling an electrically-powered device at the customer premise, comprising:

a first transceiver coupled to a meter at the customer premise and further having an identifier storable in a memory coupled to the first transceiver, the first transceiver being configured to wirelessly communicate bidirectionally according to the identifier with a remote control center via a plurality of additional wireless birdirectional transceivers that receive communications from the first transceiver and retransmit the communications, at least one of the plurality of additional wireless bidirectional transceivers being a site controller coupled to a wide area network and at least another of the one or more additional wireless bidirectional transceivers also being coupled by an interface to a meter;

a microcontroller coupled to the first transceiver and to an interface that is further coupled to an electrically-powered device, the microcontroller operable to control operation of the electrically-powered device from at least a state of powered on to a state of powered off when the microcontroller receives a predetermined signal; and

a user interface coupled to the microcontroller and operable to cause the microcontroller to implement predetermined actions in response to user input via the user interface.

5. The device of claim 4 , wherein the user interface is a keypad.

6. The device of claim 5 , wherein the user interface includes a display.

7. The device of claim 4 , wherein the electrically-powered device is an HVAC system.

8. The device of claim 4 , wherein the electrically-powered device is a lighting system.
