Controlling groups of electrical loads
First Claim
1. A load control system comprising:
- a group of lighting devices configured to control an amount of power provided to respective lighting loads; and
a remote control device configured to;
identify an actuation on the remote control device, wherein the actuation is configured to toggle an on/off state of the lighting devices;
transmit a status query message for the on/off state to at least one lighting device of the group of lighting devices in response to the actuation to identify the on/off state of the at least one lighting device prior to controlling one or more lighting devices in the group of lighting devices;
receive a status message from the at least one lighting device of the group of lighting devices, wherein the status message indicates a respective on/off state of the at least one lighting device; and
transmit a digital message configured to control the on/off state of the one or more lighting devices in the group of lighting devices.

Abstract
A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and controller devices, such as a remote control device configured to transmit digital messages for controlling the lighting load via the load control device. The remote control device may communicate with the lighting devices via a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages as unicast messages or multicast messages based on the type of user interface event detected. The remote control device, or other master device, may synchronize and/or toggle an on/off state of lighting devices in the load control system.

12. A load control system comprising:
-
a group of lighting devices configured to control an amount of power provided to respective lighting loads; and a remote control device configured to toggle an on/off state of the group of lighting devices by sending on commands and off commands, wherein the remote control device is configured to; identify a user interface event for toggling the on/off state of the group of lighting devices; transmit a default on command or a default off command to the group of lighting devices; determine that a state update message fails to be received in response to the default on command or the default off command after a predetermined period of time; and transmit an opposite command of the default on command or the default off command that was previously transmitted to the group of lighting devices. - View Dependent Claims (13, 14, 15, 16)

17. A load control system comprising:
-
a group of lighting devices configured to control an amount of power provided to respective lighting loads; a remote control device configured to toggle an on/off state of the group of lighting devices; and a master device configured to; determine an on/off state of each lighting device in the group of lighting devices; store the on/off state of each lighting device in the group of lighting devices; receive a toggle command from the remote control device; determine, from the previously stored on/off state of the group of lighting devices, that the on/off state of the group of lighting devices are out of synchronization; and transmit, to the group of lighting devices, a command that is configured to synchronize the on/off state of the group of lighting devices. - View Dependent Claims (18, 19, 20)
