Recently the Light module has been a bit potty - for example at 8.15 this moirning it goes on a 20 minute madness spree of turning on and off repeatedly.

 

This in turns kicks in the light responses and turns outside and led lights on and off quickly.

 

I did have some logic in my latest config to use timers but this resulted in the self arming to away modem problem you are looking into.

 

Does this sounds like a dodgy light module or photocell ? It\'s well protected from the elements and is encased in clear silicon (has been for over a year)

 

 

It could be either sensor or PCB, but the likely culprit is the sensor
What you see is oscillations around the threshold which causes the circuit to turn on and off. There is hysteresis built in to the circuit ie ie allows some small band before it switches back
Try another sensor for a start
