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 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.
