Abstract

Systems and methods for controlling devices, including controller and actuators are disclosed. Actuators may be devices where remote control of the device or devices is convenient, such as lights, window shades, fans and similar items. In one method, a user sends a command to a controller and to an actuator. The controller also sends a proxy update to a second controller that is also in communication with the actuator. The proxy controller, also in contact with the actuator, now has knowledge of the state or position of the actuator and is in a better position if the proxy controller is asked to assume control of the actuator. In another method, an actuator or controller may also receive a trigger setup, asking the actuator to tell the controller when an action occurs, but not to take action until receiving a further command from the controller.

Claims

1-12. -12. (canceled)

13. A method for controlling an actuator, the method comprising:

sending a trigger setup command from a controller to at least one actuator of a plurality of actuators;

receiving an indication of an occurrence of a trigger at the at least one actuator;

sending a confirmation message of the occurrence of the trigger to the controller; and

sending a trigger command to the at least one actuator in response to the occurrence of the trigger.

14. The method of claim 13, wherein the at least one actuator is selected from the group consisting of a home control device, a pump, an audio-visual device, a security device, a temperature control device, an environmental device, a lighting device, a healthcare device and a user interface device.

15. The method of claim 13, further comprising sending a confirmation message of receipt of the trigger command to the controller by the at least one actuator.

16. The method of claim 13, wherein the trigger is a switch action.

17. The method of claim 13, wherein the trigger is an event or a passage of a period of time.

18. The method of claim 13, further comprising sending a first command to each actuator of the plurality of actuators before the step of sending the trigger setup command.

19. The method of claim 18, further comprising sending the first command from the controller to a proxy controller in operable communication with the controller and the plurality of actuators.

20. A method for controlling an actuator, the method comprising;

sending a trigger setup command from a controller to at least one actuator of a plurality of actuators;

receiving an indication of an occurrence of a trigger at the at least one actuator;

sending a message from the actuator to the controller requesting a trigger command from the controller;

failing to receive the command from the controller within a period of time; and

executing a predetermined command by the actuator after the period of time.

21. The method of claim 20, wherein the trigger is initiated by a switch action.

22. The method of claim 20, wherein the period of time is 5 seconds or less.

23. A method for controlling an actuator, the method comprising:

sending a command from a controller to an actuator;

sending a confirmation message from the actuator to the controller confirming receipt of the command;

receiving a switch action at the actuator;

sending a message to the controller requesting a command from the controller;

failing to receive the command from the controller within a period of time; and

executing a predetermined command by the actuator after the period of time.

24. The method of claim 23, wherein the actuator comprises a plurality of actuators, of which at least one actuator is selected from the group consisting of a lamp, a fan, an air conditioner and a shade.

25. The method of claim 23, wherein the period of time is 5 seconds or less.

26. The method of claim 23, further comprising sending the command to at least one additional actuator or at least one additional controller.

27. The method of claim 26, wherein the at least one additional controller is in communication with the actuator and the at least one additional actuator, and wherein the step of sending the message to the controller requesting the command comprises sending the message to controller and the additional controller requesting the command.
