Abstract
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.
