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 be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.

Abstract: Provided herein are examples of a remote control device that provides a retrofit solution for an existing switched control system. The remote control device may comprise a control circuit, a rotatable portion, a magnetic ring coupled to the rotatable portion, and first and second Hall-effect sensor circuits configured to generate respective first and second sensor control signals in response to magnetic fields generated by the magnetic elements. The control circuit may operate in a normal mode when the rotatable portion is being rotated, and in a reduced-power mode when the rotatable portion is not being rotated. The control circuit may disable the second Hall-effect sensor circuit in the reduced-power mode. The control circuit may detect movement of the rotatable portion in response to the first sensor control signal in the reduced-power mode and enable the second Hall-effect sensor circuit in response to detecting movement of the rotatable portion.

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: The lighting device may be configured to perform black body curve fading. For example, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting load is adjusted (e.g., faded) along a black body curve. The control circuit may be configured to determine whether to fade from an initial color to a destination color in a Correlated Color Temperature (CCT) chromaticity space or an XY chromaticity space. The control circuit may be configured to determine whether the initial color and/or the destination color are on the black body curve. When the initial color and the destination color are determined to be on the black body curve, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting device is adjusted from the initial color to the destination color along the black body curve.
