An apparatus and method for the automatic adjustment of window coverings and the like, receiving externally-broadcast time-and-date signal as a temporal reference for making scheduled adjustments to the window covering. One embodiment comprises an antenna, a conventional broadcast time signal receiver/decoder, a motorized adjustable window covering, a conventional microcontroller with non-volatile memory, and human-operated controls for on-demand adjustments and memory commands. The broadcast time signal provides high reliability, high precision timing control, which allows synchronization of multiple units in separate windows, without the need for a central control system. Some embodiments of the invention have a learning function which is operated by making an adjustment in a conventional, familiar manner, combined with a learn command.
