Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.

Abstract: A load control device may include a semiconductor switch, a control circuit, and first and second terminals adapted to be coupled to a remote device. The load control device may include a first switching circuit coupled to the second terminal, and a second switching circuit coupled between the first terminal and the second terminal. The control circuit may be configured to render the first switching circuit conductive to conduct a charging current from an AC power source to a power supply of the remote device during a first time period of a half-cycle of the AC power source, and further configured to render the first and second switching circuits conductive and non-conductive to communicate with the remote device via the second terminal during a second time period of the half-cycle of the AC power source.

Abstract: A scalable, distributed load control system for home automation based on a network of microphones may include control devices (e.g., load control devices) that may include microphones for monitoring the system and communicating audio data to a cloud server for processing. The control devices of the load control system may receive a single voice command and may be configured to choose one of the load control devices to transmit the voice command to the cloud server. The load control devices may be configured to receive a voice command, control a connected load according to the voice command if the voice command is a validated command, and transmit the voice command to a voice service in the cloud if the voice command is not a validated command. The voice service to which the load control devices transmit audio data to may be selectable.

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.
