Motion Detection False Positive

I see that there are some old topics but my problem didn’t exist for over 6 months. It just started about 2 months ago. My lights keep turning on now because the motion detector sees motion but nothing is moving. Any idea if its the motion detector or if its the hub?

I’m sure that’s very frustrating. What’s the brand and model of the motion sensor?

Usually the best thing to do is just to start going through the regular checklist for false positives. This time of year, it’s often the heating system, but run through the list. (This is a clickable link)

FAQ: False positives on motion sensors

Hi there, I have started to get false positives with one of my SmartThings motion sensors.Anyone any idea what that could cause this? I observed it many times with definitelty no motion at all. It was during the day. The temperature is 99F. There is a security glass door which I thought was the culprit. However when I stand there myself seeing my own reflection it does not trigger a motion alert. I have several sensors all exposed to the same kind of temperature. Is is possible that this sensor went defective? Thanks, Olaf

If none of those steps seem to fix it, then the next steps will depend on the brand and model.
