Abstract

A wireless demand response endpoint includes a power switch and a wireless receiver to control the power switch in response to a wireless demand signal. The wireless demand signal may be transmitted at the same premises as the endpoint. One or more wireless endpoints at the premises may be configured to respond to the wireless demand signal. The wireless demand signal may be transmitted automatically, manually, or in other modes. Power switching may be on/off, dimming, etc.

Claims

1. A method comprising:

receiving a wireless demand signal at an endpoint; and

controlling a power switch at the endpoint in response to the wireless demand signal.

2. The method of claim 1 where:

the endpoint is at a premises; and

the method further comprises transmitting the wireless demand signal at the premises.

3. The method of claim 2 where the wireless demand signal is transmitted in response to a demand signal received from outside the premises.

4. The method of claim 2 where the wireless demand signal is transmitted in response to an action by a person.

5. The method of claim 2 further comprising controlling the power switch at the endpoint in response to a wireless control signal.

6. The method of claim 5 where the wireless control signal comprises a wireless occupancy signal.

7. The method of claim 5 where the wireless demand signal and the wireless control signal appear the same at the endpoint.

8. The method of claim 2 where the wireless demand signal includes a demand response code that causes the power switch to respond to the wireless demand signal.

9. The method of claim 2 where the wireless demand signal includes a priority.

10. The method of claim 2 where the wireless demand signal includes an address that causes the power switch to respond to the wireless demand signal.

11. A system comprising:

an endpoint device having a power switch; and

a wireless receiver to control the power switch in response to a wireless demand signal.

12. The system of claim 11 where the endpoint device includes the wireless receiver.

13. The system of claim 11 where the endpoint device may be configured to learn to respond to the wireless demand signal.

14. The system of claim 11 where the endpoint device may be configured to respond to an address in the wireless demand signal.

15. The system of claim 11 where the endpoint device may be configured to respond to a demand response code in the wireless demand signal.

16. The system of claim 11 where the endpoint device may be configured to respond to a broadcast wireless demand signal.

17. The system of claim 11 where the endpoint device may be configured to respond to a priority in the wireless demand signal.

18. The system of claim 11 where the endpoint device comprises a wall switch.

19. The system of claim 11 where the endpoint device comprises a power pack.

20. The system of claim 11 where the endpoint device comprises an outlet.

21. The system of claim 20 where outlet comprises a receptacle.

22. The system of claim 11 where the endpoint device comprises a portable switching device.

23. A system comprising:

a building energy management system; and

a wireless transmitter coupled to the energy management system to transmit a wireless demand signal to one or more wireless endpoints at the building.

24. The system of claim 23 where the system may inventory the one or more wireless endpoints.

25. The system of claim 23 further comprising a user interface to configure the system.

26. The system of claim 25 where the user interface comprises a workstation.

27. The system of claim 25 where the user interface enables a user to configure the one or more wireless endpoints to respond to the wireless demand signal.

28. The system of claim 27 where the user interface enables the user to configure individual wireless endpoints to respond to the wireless demand signal.

29. The system of claim 23 further comprising a user interface to operate the system.

30. The system of claim 29 where the user interface enables the user to initiate a transmission of the wireless demand signal.

31. The system of claim 23 where the system may transmit the wireless demand signal in response to a demand response signal received from outside the system.

32. The system of claim 31 where the demand response signal received from outside the system is transmitted by a utility.

33. The system of claim 31 where the system may transmit the wireless demand signal automatically in response to the demand response signal received from outside the system.
