Abstract
A wireless load control system for controlling one or more electrical loads comprises a wireless control device (e.g., a gateway device) able to obtain a present time from a server via a network (e.g., the Internet), control the electrical loads according to a timeclock schedule, and disable the timeclock schedule if the present time is not able to be obtained from the server via the network. The wireless control device may also be able to obtain the present time from a digital message received from an external device (e.g., a smart phone or a tablet device) via the network. The wireless control device may be configured to receive a control signal indicating a power outage (e.g., from a battery backup device), and to operate in a low-power mode in response to receiving the control signal indicating the power outage.
