    hi @cruunnerr
    I just installed it, everything looks good but not working at all. I tried via 2.1 Using PIR-Module and 2.2 Using PIR-Script both not working, any suggestion how to check where the issue is?

      I have had success with your help and my PIR sensor but only after running pir.py from .bashrc

      The script is working however I read the following warning when accessing my Magic Mirror with SSH:

      RuntimeWarning. This channel is already in use, continuing anyway. io.setup(LED_PIN, io.OUT)

      My end result is not affected. The PIR works fine.

      Thank you

        Just a little feedback that was a huge help for me.
        @cruunnerr don’t know if you want to add this information on your first message.

        I have a samsung d6000 series tv that wouldn’t work anyway with modules for PIR sensor. A BIG aplause for all developers but i coudn’t get the tv out of “No Signal” message. The MagicMirror would turn image off but tv only in “No Signal”.

        I’m not a programmer and just went on test and try.

        I figured out that the https://github.com/bugsounet/MMM-NewPIR from @Bugsounet (BIG thanks to you also!) managed the problem!!

        With this module set to mode: 4 - use HDMI CEC the TV shuts down when the MagicMirror tells her to shut down!
        It’s straight through ON and OFF as expected!

        I’me very thankful to you all managing to help us out!
        Thanks!

              This one. Mentioned in the first page.
              how to remove it?

              #!/usr/bin/env python

              import sys
              import time
              import RPi.GPIO as io
              import subprocess

              io.setmode(io.BCM)
              SHUTOFF_DELAY = 120 # in seconds, how long the monitor will be on until next button press or PIR detection
              PIR_PIN = 22 # 15 on the board (this needn’t to be a PIR. Can be a button also)
              LED_PIN = 16 # optional, don’t use as Relay-PIN. It just shows detection time of the PIR without delay time

              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/monitor_on.sh”, shell=True)

              def turn_off():
              subprocess.call(“sh /home/pi/monitor_off.sh”, shell=True)

              if name == ‘main’:

              main()
              except KeyboardInterrupt:

                  Hello everyone, I’m getting desperate. I’ve now read the entire tutorial but I can’t find my mistake.

                  I am using my MM with a PIR sensor and would like to switch the backlight of the display with a relay. so i use this script pir.py:

                  #!/usr/bin/env python
                  
                  import sys
                  import time
                  import RPi.GPIO as io
                  import subprocess
                  
                  io.setmode(io.BCM)
                  SHUTOFF_DELAY = 120 # in seconds, how long the monitor will be on until next button press or PIR detection
                  PIR_PIN = 22       # 15 on the board (this needn't to be a PIR. Can be a button also)
                  LED_PIN = 16      # optional
                  
                  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/monitor_on.sh", shell=True)
                  
                  def turn_off():
                  	subprocess.call("sh /home/pi/monitor_off.sh", shell=True)
                  
                  if __name__ == '__main__':
                      try:
                          main()
                      except KeyboardInterrupt:
                          io.cleanup()
                  
                  

                  Unfortunately, when I run this script in the terminal, I only get the feedback from the PIR sensor (…) but the relay is not switched. But if I run the monitor_on.sh or monitor_off.sh script it works:

                  monitor_on.sh

                  gpio -g mode 27 out
                  sleep 0.2
                  gpio -g write 27 1
                  

                  monitor_off.sh

                  gpio -g mode 27 out
                  sleep 0.2
                  gpio -g write 27 0
                  

                  But the PIR.py doesn’t work. Where could the mistake lie?

                  Many greetings Andreas

                    @andi-aw-weiss I think you are using the wrong script. With just a quick look it seems you’re running the script from point 2.2 (Using PIR script) of the first post. What you want is point 5.2 (Use relay with a PIR). That script used in 5.2 is different than that of 2.2, which does not have code to control the relay.

                    Have a look at it again.

                      @MadScientist Hey, unfortunately the problem hasn’t changed. I have now like you said the script from 5.2. The problem remains. PIR detects motion. Relay does not switch. :loudly_crying_face: I don’t know
