  • Publication number: 20220353978
    Abstract: A remote control device may be configured to transmit command messages based on user interactions. The remote control device may receive an indication of a user interaction and transmit a command message based on the indication of the user interaction. The command message may include a command to adjust an intensity level of a lighting device and a fade period. The fade period may include the period of time over which the lighting device is to transition to the intensity level. After a transmission interval period of time from when the command message was transmitted elapses and based on a subsequent user interaction, the remote control device may transmit another command message, which may include a command for the lighting device to adjust to another intensity level over the fade period. The fade period may be longer than the transmission interval.

  • Publication number: 20220345363
    Abstract: A load control system may be commissioned using beacons. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacons are received. The control devices may provide feedback to a user in response to confirmation messages to indicate to a user that the lighting control device has been added to the temporary group. The control devices may stop providing the feedback after they are removed from the temporary group.

  • Publication number: 20220230533
    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.

  • Publication number: 20220113936
    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.

  • Publication number: 20220078897
    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.
