<p>A programmable switching unit which may be incorporated in a switch for installation in a standard switch box, or into a single or multi-adaptor for connecting one or more appliances to a wall outlet, the unit being switchable between a first, learning mode, in which it updates a table of transitions between ON and OFF states of a controlled appliance over several days, and a second, automatic mode in which it generates a sequence of switching operations over a subsequent days. The sequence is generated by logically combining the times of switching events store over several days, and timing of each individual event in the sequence is subject to a limited random time shift. <IMAGE></p> |
