Abstract

A load control system may include one or more wireless control devices that may be associated via a programming device. An identifier for a first wireless control device may be determined in response to an actuation of a button on the first wireless control device. An association between the first wireless control device and a second wireless control device may be defined at the programming device. The identifier for the first wireless control device may be transmitted to the second wireless control device, which may cause the first wireless control device to enter a sleep mode. The first wireless control device may enter the sleep mode after an actuation of a button on the first wireless control device. The identifier may be determined in response to the actuation of the button on the first wireless control device and/or prior to the first wireless control device entering the sleep mode.

Claims

1. A load control system comprising:

a load control device configured to control an electrical load;

a remote control device comprising a button for receiving a user input, the remote control device configured to store in memory an identifier for the remote control device in response to a first actuation of the button, wherein the remote control device is configured to enter a sleep mode after the first actuation of the button, and wherein the remote control device is configured to determine the identifier for storage in memory prior to the remote control device entering the sleep mode; and

a programming device configured to define an association between the remote control device and the load control device;

wherein the load control device is configured to store the identifier of the remote control device in memory in response to the programming device defining the association between the remote control device and the load control device, wherein the remote control device is configured to transmit a digital message in response to a second subsequent actuation of the button, the load control device configured to control the electrical load in response to the digital message.

2. The load control system of claim 1, comprising:

a gateway device configured to store the identifier of the remote control device in memory in response the first actuation of the button.

3. The load control system of claim 2, wherein the remote control device is configured to choose a first random number in response to the first actuation of the button, the remote control device configured to transmit a query message to the gateway device to determine if the first random number is presently being used as an identifier of another control device of the load control system.

4. The load control system of claim 3, wherein the remote control device is configured to choose a second random number if the first random number is presently being used as the identifier of another control device.

5. The load control system of claim 3, wherein the remote control device is configured to store the first random number in memory as the identifier if the first random number is presently being unused as the identifier of another control device.

6. The load control system of claim 3, wherein the remote control device is configured to wait for a predetermined amount of time to receive the identifier from the gateway device prior to choosing the first random number, the remote control device configured to choose the remote control device fails to receive the first random number from the gateway device within the predetermined amount of time.

7. The load control system of claim 2, wherein the gateway device is configured to choose the identifier based on the identifier presently being unused by another control device in the load control system and to transmit the identifier to the remote control device.

8. The load control system of claim 2, wherein the programming device is configured to transmit association information defining the association between the remote control device and the load control device to the gateway device, and wherein the gateway device is configured to transmit the identifier to the load control device.

9. The load control system of claim 2, wherein the programming device is configured to transmit a command to cause the gateway device to enter an association mode before the first actuation of the button of the remote control device.

10. The load control system of claim 2, wherein the gateway device is configured to transmit the identifier to the programming device, and the programming device is configured to store the identifier in memory.

11. The load control system of claim 2, wherein the gateway device is configured to transmit the identifier to the remote control device in response to the first actuation of the button on the remote control device.

12. The load control system of claim 11, wherein the remote control device is configured to transmit a second digital message in response to the actuation of the button before the remote control device determines the identifier, the gateway device configured to transmit the identifier to the remote control device in response to receiving the second digital message from the remote control device.

13. The load control system of claim 11, wherein the remote control device is configured to transmit a second digital message for identifying the remote control device in response to the first actuation of the button before the remote control device determines the identifier, wherein the gateway device is configured to transmit the identifier to the remote control device in response to receiving the second digital message from the remote control device.

14. The load control system of claim 11, wherein the remote control device is configured to transmit a second digital message for controlling the load control device in response to the first actuation of the button before the remote control device determines the identifier, the gateway device configured to transmit the identifier to the remote control device in response to receiving the second digital message from the remote control device.

15. The load control system of claim 1, wherein the programming device is configured to define the association between the remote control device and the load control device before the remote control device stores the identifier in memory.

16. The load control system of claim 1, wherein the remote control device is configured to store the identifier in memory before the programming device defines the association between the remote control device and the load control device.

17. A gateway device for a load control system, the gateway device comprising:

a communications circuit configured to receive a selected group number from the remote control device; and

a processor configured to determine whether the selected group number from the remote control device is in use by another control device in the load control system.

18. The gateway device of claim 17, wherein the communications circuit is configured to transmit whether the selected group identifier is in use by another control device in the load control system.

19. The gateway device of claim 18, wherein the group number transmitted from the communications circuit is configured to cause the remote control device to wake from a sleep state.

20. A remote control device for a load control system having a load control device configured to control an electrical load, the remote control device comprising:

a processor configured to;

store in memory an identifier in response to a first actuation of a button;

enter a sleep mode after the first actuation of the button; and

determine the identifier before the remote control device enters the sleep mode, wherein an association is defined between the remote control device and the load control device; and

a communications circuit configured to transmit a digital message in response to a second subsequent actuation of the button, wherein the electrical load is controlled in response to the digital message.

21. The remote control device of claim 20, wherein the remote control device remains in the sleep mode until a button of the remote control device is actuated.

22. A programming device for a load control system having a load control device configured to control an electrical load, the programming device comprising:

a processor configured to;

cause a gateway device to enter an association mode; and
