A lighting control module (LCM) includes an input configured to receive, from a sensor, a signal indicative of motion and/or occupancy, and to output a first corresponding signal. The LCM includes a microprocessor to receive the first corresponding signal from the input and, in response, transmit a second corresponding signal. A wireless transceiver is communicatively coupled to the microprocessor and configured to communicate with other LCMs. A relay is configured to selectively provide power to an output that is configured to be electrically coupled to a fixture. The relay is configured to selectively provide the power to the output according to a first relay-control signal from the microprocessor. The LCM also includes a regulated power supply, a power input configured to couple the power supply to an external power source, and a dimming module configured to be coupled to the fixture and to, when coupled to the fixture, output a signal to the fixture. The LCM is configured to receive from the sensor the signal, and in response to the signal cause the fixture to change its state of operation.

A dual-control dimming system is disclosed. The dual-control dimming system is configured to automatically change control of an LED between two control loops as an LED output is adjusted over a dimmable range. A first control loop may take control of the LED output in a first portion of the dimmable range, while the second loop may take control of the LED output in a second portion of the dimmable range. In this way, the LED may be powered efficiently in the first portion, while providing stable (i.e., flicker-free) output in the second portion.

A load control system may include control devices for controlling power provided to an electrical load. The control devices may include an input device and a load control device. The load control system may include a hub device. The hub device may include a communication circuit and a control circuit. The communication circuit may be configured to receive a digital message from the control device. The control circuit may be configured to determine, based on content of the digital message, whether the control device has experienced a power removal event. The hub device may send, via the communication circuit, a power removal event indication to the control device of whether the control device has experienced the power removal event.
