Hi, I’m after some advice please. I have a coach lantern light fitted outside connected to a switch. It has a motion PIR sensor. Usually at night time it comes on when it’s detected motion, then switches off after a few minutes. The other week we had a power cut and now at nighttime it won’t switch off, just stays on until about n the mirning I’ve done the on, off and wait 20 seconds then on again. It comes on, then flashes 3 times, goes off. then when motion is detected I think, it just stays on again. I’m just want it to come on when motion is detected then go off. Any ideas please? Thanks
