[QUOTE="ProDave, post: 493242, member: 6969"] This job has come to life again. the owner came across the control box for these sensors, cut into the back of a kitchen cupboard behind the cornflakes. [ATTACH]10434._xfImport[/ATTACH] So, the issue is, the two motion sensors work, but the daylight sensor(s) have failed, so it triggers at any time of day if you walk past. So I hatched a cunning plan. I fitted a daylight sensor. The output of the daylight sensor now powers up this box only when it is dark. I expected it to then continue operating on the motion sensors during darkness, but be off in the daytime. Not so, my customer phoned this morning to say the lights were on permenantly all night from dusk until dawn. What could be wrong? [/QUOTE]
