Abstract: A load control system may include load control devices for controlling power provided to an electrical load. The load control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. A user device may discover load control devices when the load control devices are within an established range associated with the user device. The user device and the load control devices may communicate via a wireless communications module. The established range may be adjusted based on the configurable transmit power of the user device or the wireless communications module associated with the user device. A discovered control-target device may be associated with a control-source device to enable the control-target device to control the power provided to the electrical load based on digital messages received from the control-source device.

Abstract: A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.

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 load control system may include control devices for controlling power provided to an electrical load. The control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. The control devices may include a load control discovery device capable of sending discovery messages configured to discover control devices within a location. The discovered control devices may be organized by signal strength and may be provided to a network device to enable association of the discovered control devices within a location. The discovery messages may be transmitted within an established discovery range. The discovery range may be adjusted to discover different control devices. Different control devices may be identified as the load control discovery device for discovering different control devices.
