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 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.
Abstract:
A load control system (100) includes control devices for controlling electrical loads, such as a motorized window treatment (130) and lighting devices (112, 122). The control devices include load control devices, such as a lighting device (112, 122) for controlling an amount of power provided to a lighting load, and input devices, such as a remote control device (116) configured to transmit digital messages comprising lighting control instructions for controlling the lighting load via the lighting device. The remote control device (116) may communicate with the lighting device (112, 122) via an intermediary device, such as a hub device (180). The remote control device (116) detects a user interface event, such as a button press or a rotation of the remote control device. The remote control device (116) or the hub (180) device determines whether to transmit digital messages to as unicast messages or multicast messages based on the type of user interface event detected. The load control devices may also include a motorized window treatment (130). The input devices may also include a remote control device (150), an occupancy sensor (160), a daylight sensor (170), and a network device (190), such as a smart phone, which may include a visual display (192). The remote control device (116, 150) or the hub device (180) may transmit the digital message as a unicast message when the user interface event is determined to be an "on" event or an "off" event and the number of multicast messages transmitted within the predefined period of time is outside of a predefined threshold. The remote control device (116) may be a retrofit remote control device capable of covering a switch installed on the wall-mounted load control device (110). The remote control device (116, 150) or the hub device (180) may calculate a delay between the transmission of each unicast message. The delay may be injected between unicast messages to help ensure that the communication link is idle prior to the device sending the next unicast message.
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.
