      More or less the same problem for me…
      I’m using a velleman VMA314 connected to GPIO pin 11 (BCM GPIO 17) and module MMM-PIR-Sensor.
      I’ve updated wiringPi for Pi 4 (wiringPi updated to 2.52 for the Raspberry Pi 4B)
      I see that state changes using ā€œgpio readallā€ but nothing happens…or to start with, connected screen does not even turn off after time set in config:

      		{
      			module: 'MMM-PIR-Sensor',
      			config: {
      			// See 'Configuration options' for more information.
      				sensorPin: 17, // The pin (BCM numbering, NOT pin number itself) your PIR-sensor is connected to.
      				powerSaving: true, // Should the monitor be turned off if no user is present? (via HDMI or relay)
      				powerSavingDelay: 5, // Additional software side delay (in seconds) before the monitor will be turned off.
      				powerSavingNotification: true, // To display a notification before to switch screen off
      				powerSavingMessage: "SkƤrmen stƤngs av pƄ grund av inaktivitet..." // Message notification to display before to switch screen off
      				
      			}
      		},

                @sdetweil :rolling_on_the_floor_laughing:
                Yes, i’ve built two mirrors and now working on my third bathroom mirror and with x number of files open in Notepad++ it’s getting messy…and even if you can see the file name and it’s location (host name) you end up editing elsewhere :dizzy_face:

                  What type of mirror glass do you all have?

                  I have a Pilkington Mirropane Chrome Spy and to me it seems that this type of Mirror glass interferes with the RCWL-0516.

                  When doing tests (mirror glass taken off) the sensor works as expected but as soon as I put the mirror glass back it stops working through the glass.
                  Waving my hand at the side still works.

                    @devmil I have the same mirror, but 4mm thick, and it works really well. Thickness shouldn’t be an issue, because the sensor is easily able to detect motions in adjacent rooms separated by stone walls. Iā€˜d suggest to increase slightly the sensitivity by increasing the trimmer value.

                    Further check the soldering joints between trimmer and sensor. Maybe they need to be reworked so that the solder provides a proper connection.

                      @devmil Hi Michael, i’ve been testing with d-c-fix mirror-effect privacy film and acrylic oneway mirror and both is interfering the PIR sensor so i had to put in a small box above the frame. Not a fancy design though…
                      For the acrylic i have spare place beneath the screen so i drilled a hole.
                      For the upcoming bath mirror i’ve ordered a Pilkington MirrorView. Don’t know yet if it will work with the sensor behind that glass though…otherwise i’ll put in a separate place/box. Hard to drill the glass and wouldn’t dare trying :-|
