      are u sure, u are using the correct pin?
      The Module uses BCM numbering, so if u write in your config to use 22, it is physically 15, and this is GPIO 3!

      type in console, while u are running through the PIR:

      gpio read 3
      

      before detecting it must give out a “0”. WHILE moving through the PIR it must give out a “1”

      or simply type gpio readall before and while the PIR detects to compare results and see what Pin you are really using.

      and please check if pm2 gives errors with pm2 logs

        OH nice so now we’re deleting messages…Thanks appreciate that…

        We all are here for some fun. But mentioning “dynamite” several times doesn’t help the user and it does not make your joke better.

          @cruunnerr I’m using the correct pin. I made a python script shown below:

          from gpiozero import MotionSensor
          pir = MotionSensor(22)
          while True:
          if pir.motion_detected:
          print(“motion detected”)
          else:
          print(“NOTHING”)

          With this it will print nothing until i wave my hand in front of it then motion detected until i stop. So I know for a fact the PIR sensor is connected and working properly. Also there are no errors when I start magic mirror the only thing that is mentioned about MMM-PIR-Sensor is it says no helper found for module: MMM-PIR-SENSOR. Anyone have any idea

            have u tried to delete the Pir Folder in your modules direction and start a simple new installation of the module?

            or just go into the MMM-PIR-Sensor folder and type npm install again?

              @cruunnerr I just deleted the entire module and downloaded it again, following the instructions directly from the page.

              To summarize, I know the sensor is working properly and connected to the right pin listed in the config file. I know nothing is wrong with the module i just downloaded it from github. I’ve posted the exact copy of my config file, no one seems to have a problem with that. What else could it be? For some reason the monitor wont shut off.

              Its a Benq monitor connected to the raspberry pi via an hdmi cord.
              Im not sure if this helps but when i type /opt/vc/bin/tvservice -s:
              state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive

                  why are you using a MM module?
                  This is not related to the mirror itself. Use @cowboysdude (how funny is that in this context ;) ) script.
                  You can find it in his github respository. By the way, this dude creates really cool stuff, so its worth to have a closer look to it.

                  If your PIR is cabled well, it should work easily.

                    mba , I had the same issue but only because you have to force one detection, just the first time after you start magic mirror software. Then everything should be ok and working. So, after magic mirror is up and running, try to pass an hand in front of the sensor, then wait to see if it will turn off.

                      I had the same problems and I dont know why. So I searched for another solution. Now it works perfect.
                      I wrote one bash script for the power off and one for the power on.

                      Script Power on:
                      vcgencmd display_power 1

                      Script Power off:
                      vcgencmd display_power 0

                      than I used this Pyhton for the PIR

                      #!/usr/bin/env python
                      
                      import sys
                      import time
                      import RPi.GPIO as io
                      import subprocess
                      
                      io.setmode(io.BCM)
                      SHUTOFF_DELAY = 300  # seconds
                      PIR_PIN = 25        # 22 on the board
                      LED_PIN = 16        # 36 on the board
                      
                      def main():
                          io.setup(PIR_PIN, io.IN)
                          io.setup(LED_PIN, io.OUT)
                          turned_off = False
                          last_motion_time = time.time()
                      
                          while True:
                              if io.input(PIR_PIN):
                                  last_motion_time = time.time()
                                  io.output(LED_PIN, io.LOW)
                                  print ".",
                                  sys.stdout.flush()
                                  if turned_off:
                                      turned_off = False
                                      turn_on()
                              else:
                                  if not turned_off and time.time() > (last_motion_time + 
                                                                       SHUTOFF_DELAY):
                                      turned_off = True
                                      turn_off()
                                  if not turned_off and time.time() > (last_motion_time + 1):
                                      io.output(LED_PIN, io.HIGH)
                              time.sleep(.1)
                      
                      def turn_on():
                          subprocess.call("sh /home/pi/MagicMirror/pir/monitor_on.sh", shell=True)
                      
                      def turn_off():
                          subprocess.call("sh /home/pi/MagicMirror/pir/monitor_off.sh", shell=True)
                      
                      if __name__ == '__main__':
                          try:
                              main()
                          except KeyboardInterrupt:
                              io.cleanup()
                      

                      I tryed to upload but not enough privileges

                        @sek_is_back hi know this is old but where do you save the scripts to, to make them function?
