UPDATE: Replaced my PIR-Sensor with a Doppler Microwave Sensor.

@mickyvi as the last option maybe install the sensor on top or bottom of the mirror frame. Hide it in a small enclosure (wooden or hard paper or 3D printed extension to the frame) and paint the same color as the frame. If done nicely it won’t even look that bad. And it will for sure work :)
-
@mickyvi That’s indeed really strange, and I can only guess that the mirror has a reflecting coating which prevents the signal from passing through the mirror. The thickness of the glass itself is not the limiting factor, as the signal usually passes even stone walls and can detect motion in adjacent rooms. I operated my sensor first behind the mirror, too, and it worked. It is a 4mm Pilkington. Later I moved it under the frame, because it was easier to trim the sensor and hid it behind a 3D-printed cover. Thus, I’d second @uros76 proposal to mount the sensor on top or on the bottom of the frame where it is not visible. Don’t give up!

Hello everybody,
I’m taking the path of the classic infrared PIR sensor.
I made two shells that can be attached under the two arms of the lamps above the mirrors.
Here still in the assembly / painting phase:
I’m gonna give a nice coat of chrome today and we should be there. :-)

@mickyvi That’s a totally awsome solution! Really cool!

Thanks, the compliments from such experienced people are always very welcome !! -

Thank you for this awesome solution! I just got mine up and running with MMM-PIR-Sensor. I was wondering if any of you have got this microwave sensor to also work with MMM-NearCompliments? I was thinking since it was also inspired by PIR sensor, I could get it to work, but no luck yet.

hello,
i tried this with the microwave sensor, but im out of ideas. i get wrong positives every minute. (i check every 5 sec).
i added also the ferrite, tried another raspberry, different of these sensors (bought a 5 pack) and placed it in a different room. anyone got any ideas what else i could try?
or maybe similar microwave sensors i could try?any help would be great, tyvm

Did you try and limit the range as described in beginning of this thread? For me option 2 helped to limit oversensitivity.

@uros76
the range is not the problem. i get positives when nothing is moving near it -
@Lipax this sensor is very sensitive and catches any movement 360 around from several meters away. I had same problem… If you don’t dial down the sensitivity-range you will keep getting false positives.
