    You wrote that you are using a double sensor is that this one?

          @Ghost2000 no, it is a single sensor. You probably got irritated by the noun „Doppler“. This has nothing to do with double or to similar. The sensor uses an effect which was discovered by the physicist Christian Doppler. See also https://en.m.wikipedia.org/wiki/Doppler_effect

              Hi @Fozi ,

              just to make sure that I am on the right way:

              • Buy a RCWL-0516 module
              • Wire the module to my Raspberry Pi 4
              • Install @Bugsounet MMM-NewPIR on my MM

              That’s it? Or did I miss something?
              My MM is not a mirror, more a wall-mounted picture frame with some nice to have information on it. I would like to have the monitor turned off, if nobody is in the room.

              Thank you,

              Christian

                @MajorC yeah, that are the steps to go. The RCWL-0516 module is a 1:1 replacement of the common IR sensors usually used. MAke sure to follow also the instructions I wrote (see link in my signature).

                  @fozi

                  Good morning,

                  I also used a PIR sensor and obviously, behind the glass it does not work (the glass is 6 mm thick and the back of wood 3 mm), also I do not want it visible as the mirror will be positioned in the bathroom and behind I the power supply, so no wires remain in sight.

                  At the end of the story I found this topic and I also wanted to change the presence sensor.

                  I made my purchases as instructed and started testing.

                  The first test I did without modifying anything, simply connected, installed the MMM-Pir Paviro configured and it immediately started to work.
                  But I noticed one thing, my sensor is not so sensitive (indeed) I think it depends on those 9 mm total between the size of the mirror and the wooden board, if I move from behind and if I leave it too attached to the tablet wood does not detect anything (it detects only on the back or by moving the mirror from the wall).
                  I will also try to build a box to keep the sensor a little detached from the wood and let’s see what happens.

                  Any suggestions on this?

                  In the meantime, thanks to everyone for the advice and good construction with your MM.

                  Hello

                    @mickyvi in my case it was the opposite experience. I have 3mm thick glass and back of the glass is covered by matte black paper. The initially installed microwave sensor (behind glass and paper) was too sensitive and could pick up movement up to 4-5m distance. That was too much for me so I had to modify the sensor by adding a trimmer.
                    Once the trimmer was added I could dial in the sensitivity as needed.
                    Here is my mirror… https://forum.magicmirror.builders/topic/13430/my-first-slim-mirror-at-home

                    In your design, maybe cut a hole in the wood back cover to fit the sensor in. That way the sensor will only need to go through 6mm glass. You can cover the space of the hole with black paper to eliminate any light entry there.
                    It’s hard to recommend anything smarter without knowing the details of your design. Do you have any picture you could share so we can see how the back of the glass enclosure looks like?

                      Hi Uros,

                      I also thought of making a window and putting the sensor in there in order to eliminate 3 mm of thickness and in fact I think it will be the first test I will do.

                      Unfortunately today I am at work and I will be able to carry out studies and modifications only tomorrow when I have the day off.

                      I have no photos of the rear, very simple cmq, a wooden frame covered in metal 100 x 40 cm, a 6 mm Mirastar mirror, a 3 mm plywood tablet painted in black on which the various electronic devices are placed.
                      Tomorrow I will take some photos inside the outside as well, at the moment it is like this:
