Its a while since I had the panel off but I think I remember that each zone had a limit of X number of magnetic contacts and 1 PIR
could a failing one be affected by the light as mentioned.
Jesus ….you said it was a door contact , now you’re saying you also a pir on the same zone ! I would be looking at this first as you said it happens when it is hot ! ….
You are right - sorry but I as I have had problems with door/ window contacts in the past I automatically thought of them and overlooked the PIR which I have never had any issues with.
So in circumstances like mine with intermittent false trigger on a zone with any number of magnet contacts and just 1 PIR then you would always head straight to the PIR and start there
For now until I have more time could I just stick a piece of insulating tape on the sensor. It actually points at something that already has a magnetic contact anyway so I could do away with it all together.
