Do you use a PIR sensor? How do you hide it?

    maybe you only need 2mm of that to make the sensor work…

    Yeah, that’s my understanding. I can’t find the post but it was here on this site. A guy did some experiments to find the smallest size hole his PIR sensor actually required. He tried 1mm, 2mm and 4mm(?). He said it worked just fine with a 2mm hole.

    You are referring to this one: https://forum.magicmirror.builders/topic/557/pir-sensor-behind-glass/33

      I’ve made an 8 mm hole, as you can see here:

          @qu1que Having other lights there like you do makes it fit in a little better. That’s something to think about. Maybe I’m trying to make mine look too old-fashioned.

            I made a 8 mm hole on the backside and a 2 mm hole on the frontside.
            Removed the cap from the motion sensor and placed it in the 8 mm hole.
            Works great and you can hardly see the 2 mm hole.

              Nice pic, thanks for showing us how it actually looks.

              It still bugs me though. Looking at yours I wonder if putting a power light (or something light) next to the PIR hole would make the PIR hole look like less of a forced design choice. You know, it could even be a chiche looking light that blends into the wood and lights up in such a way that it doesn’t make the mirror look tacky and also doesn’t give you the feeling that it’s like a monitor power light.

              I don’t know what that would look like. Not super bright. Maybe kind of dull but not so dull that it looks weak. Maybe a good complimentary color to the wood. Maybe not a circle or a rectangle but a cool shape like a rhombus. Maybe you could put a logo or text of some sort on the face of the mirror and hide the hole there and it wouldn’t look out of place.

                I still have to paint the frame, thinking of a kind of ‘white-wash’ so you keep seeing the wood grains. Maybe it’s less ‘obvious’.
                But you know and I know, but most visitors I’ve had didn’t even see it or looking for it 🤔

                    You May also think of some different solution: I‘m using a Hue Motion detector which is in my corridor anyway and controls the MM via MM-remotecontrol using the Http get requests through HomeKit and homebridge

                      I did not use PIR sensor because it needs to “see” through the frame. After a little research I found an microwave based motion sensor called
                      RWCL-0516. This tiny PCB works super reliable even though ma 20mm thick wooden frame.
