A load control system may include control devices for controlling power provided to an electrical load. The control devices may include an input device and a load control device. The load control system may include a hub device. The hub device may include a communication circuit and a control circuit. The communication circuit may be configured to receive a digital message from the control device. The control circuit may be configured to determine, based on content of the digital message, whether the control device has experienced a power removal event. The hub device may send, via the communication circuit, a power removal event indication to the control device of whether the control device has experienced the power removal event.

State retention load control system

A control system may comprise a plurality of audio output devices (e.g., controllable speakers), and a remote control device having at least one button for selecting a preset, where the preset defines different commands for at least two of the audio output devices. The at least two audio output devices may be configured to be controlled according to the different commands (e.g., starting, pausing, or stopping playback, adjusting volume, etc.) in response to an actuation of the button of the remote control device. The control system may also comprise a load control device, such as a dimmer configured to control an intensity of a lighting load to a predetermined intensity in response to the actuation of the button of the remote control device to select the preset. The audio output device may be configured to play a feedback signal indicating an operational characteristic of the dimmer.

Load control system having audio output devices

A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g., capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g., capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).

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 input devices, such as a remote control device configured to transmit digital messages comprising lighting control instructions for controlling the lighting load via the lighting device. The remote control device may communicate with the lighting device via an intermediary device, such as 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 to as unicast messages or multicast messages based on the type of user interface event detected.

Controlling groups of electrical loads via multicast and/or unicast messages

A load control system for controlling an electrical load may include a sensor, a remote control, and a load control device. The remote control may comprise a button and may be configured to wirelessly transmit a digital message in response to an actuation of the button. The load control device may be configured to control the electrical load, be responsive to the sensor, and/or be configured to be associated with the remote control. The load control device may be responsive to the digital message transmitted by the remote control if the remote control is associated with the load control device. The load control device may be configured to automatically operate in a first mode of operation if the remote control is not associated with the load control device, and automatically operate in a second mode of operation if the remote control is associated with the load control device.
