I checked the Firmware Version: 1.0.10 which is the latest for this switch. I tried all 3 settings for motion detection with same behaviour. I am 100% positive there is no motion when lights turn on by itself after a short delay (a min or so after it was turned off by no motion). I even left the room to make sure there is no motion.

Anyway, just to narrow down the problem, I totally turned off Ambient sensor (though it is properly set for that room) both at settings and the rules and use just motion which seem to work. I did see a release notes for firmware version 1.0.10 (see below) which seem to indicate some smartcontrol issue was fixed I wonder it was not fixed in all scenarios like mine with using ambient sensor + motion sensor?

Have you found a solution? I'm having the same problem and considering returning the switch as I got it because kids can't seem to turn off the bathroom light. Now it's on even more with it turning itself on.

After fighting w/ it for a while, I disabled motion sensor completely since it does generate random motion events repeatedly and is not very useful for me. So I am using it as a just as a smart switch which seem to work fine ofcourse :)

As you can see the tp-link support is not very useful.

Still looking for a motion sensor and haven't found one that works for me. I needed just a plain (no switch, bulb etc needed) motion sensor that works w/ google assistant and able to generate motion events supported by google home scripts so I can do automation like these below.
