I have security lights which are powered by time switches. When there are power cuts etc. the timers are all wrong. I was thinking of linking the timers to a dawn/dusk sensor, which would activate the lighting at dusk until the timer switched them off. There is no problem doing this for one activation but is there a way this system could continue without having to reset the timer after each power cut ?
I feel sure there is but am baffled !
