I have Sonoff motion sensors in the garage but at night time they often falsely (report) switch on lights. I have currently set it up through Smartthings automation, if front or the back motion sensor detect movements to switch on the lights. I know Sonoff stuff are cheap and can be unreliable but I don’t want to buy an expensive motion sensor yet.
I had an idea and I’ve been looking for a solution but to no avail.
I was thinking if I put 2 x motion sensors (to detect the same location), code them to check on each other before triggering a virtual switch that will then switch on the light. For example if motion A sensor falsely reports a movement and sensor B didn’t see movement then it (the virtual switch) will not trigger the light.
I have seen this thread Combine 2 motion sensors into 1 virtual/simulated motion sensor? but this is combining the sensors
Please advise!
seems like you want a similar concept as the thread you linked. It is sometimes called “cross zoning” in burglar alarm systems. I do not have a recommendation about how to implement cross-zoning recently.
You think the cause may be insects or spiders on the sensors? I have/had that issue, creating false alarms/motions. Sticky traps will reduce the bugs and the false reports. These (Catchmaster) work great:
There is a surprising amount of activity in MY garage at night, between dust-motes close to the camera, and moths, and occasional mice. Perhaps yours is real activity and you want to put out some mouse traps.
thanks, no definitely no mouse moving or any insects (it’s too cold for them on the UK). I have taken the sensors apart and cleaned it, I have even replaced one but the problem remains the same. I think when it gets cold at night time the sensor plays up.
