      Hey sorry, i thought u disabled the MMM-PIR for sure.

      U cannot use both (Module and the script) at the same time.

      Thats because i said u should disable the autostart in the rc.local to see if the MMM-PIR is active.

      So please disable the module and just use the script. Then the pkill command will work as u want :)

        everything is working after disabling module :)

        just one remark there is needed to add also to crontab to turn off monitor at f.e. 21:02 because if there will be movement in last seconds before pir.py will be killed monitor will stay on :)

          @Module-Developers im trying to do something a bit different maybe you can help.
          I’d like to use PIR but I also want that on one particular day of the week PIR shouldn’t work and it should stay on no matter what.
          Is that possible?

            Read the last few posts ;)

            For example u want to use the pir from Sunday 22pm over the whole week until next Sunday 6am.
            So on every Sunday from 6am to 22pm the monitor should stay on.

            So you just need two cronjobs. On Sunday, 6am u need to kill the pir.py and on Sunday, 22pm you need to start it again :)

            Try it like this:

            1. nano killpir.sh

            2. Write this into file and save with CTRL+X and Yes

            #!/bin/bash
            sudo pkill $(ps aux | grep python pir.py | awk '{ print $2 }')
            vcgencmd display_power 1
            
            1. chmod +x killpir.sh

            2. sudo nano /etc/crontab

            3. Write this into file and save with CTRL+X and Yes:

            0 22 * * 7 /usr/bin/sh /home/pi/killpir.sh
            0 6 * * 7 /usr/bin/python /home/pi/pir.py
            

            So for example your crontab looks like this:

            # /etc/crontab: system-wide crontab
            # Unlike any other crontab you don't have to run the `crontab'
            # command to install the new version when you edit this file
            # and files in /etc/cron.d. These files also have username fields,
            # that none of the other crontabs do.
            
            SHELL=/bin/sh
            PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
            
            # m h dom mon dow user  command
            17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
            25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
            47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
            52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
            0 22    * * 7   root    /usr/bin/sh /home/pi/killpir.sh
            0 6     * * 7   root    /usr/bin/python /home/pi/pir.py
            #

                I tried your script but unfortunately it doesn’t seems to work yet. Like @blebbens , my MM is on the floor and activated a little bit too easy.

                Any other suggestion?

                Regards,

                  Well, for my solution it is totally necessary to NOT use the PIR-Module. You must use just my external script solution!
                  Tests i made working fine… :)

                  Anyhow… You could try to use clear nail polish.

                  I used it to cover certain regions and it works :)
                  Just paint several layers of the polish over the area u want to cover.

                  Or play with the sensitivity

                    I actually use option 2.2 - external script and already set both sensitivity and time delay to minimal (all the way to left).

                    would you mind to send me your pir.py?

                    Regards,

                      Sure, my pir.py is the same as shown on point 2.2 but with other GPIO used

                      #!/usr/bin/env python
                      
                      import sys
                      import time
                      import RPi.GPIO as io
                      import subprocess
                      import pigpio
                      
                      io.setmode(io.BCM)
                      SHUTOFF_DELAY = 119 # seconds
                      PIR_PIN = 25       # 22 on the board
                      LED_PIN = 16
                      
                      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/lights_on.sh", shell=True)
                      
                      def turn_off():
                              subprocess.call("sh /home/pi/lights_off.sh", shell=True)
                      
                      if __name__ == '__main__':
                          try:
                              main()
                          except KeyboardInterrupt:
                              io.cleanup()
                      

                      Because i use some LED Stripes which turn on when the pir detects movement my “monitor_on.sh” is called “lights_on.sh”

                        Thanks @cruunnerr.

                        In my case, no LED involved hence should be simpler :)

                        I run PIR.PY externally (via PM2) to call monitor on/off shell script and everything seems to work fine i.e.: turn screen blank and back on does work. No error reported. Its just the adding your script does not seems to make any difference, the turn on still instant.

                        Here is my PIR.py file

                        #!/usr/bin/env python
                        
                        import sys
                        import time
                        import RPi.GPIO as io
                        import subprocess
                         
                        io.setmode(io.BCM)
                        SHUTOFF_DELAY = 15  # seconds delay to turn off
                        PIR_PIN = 17        # Pin 11 on the board
                        TURNON_DELAY = 10   # seconds delay to turn on
                         
                        def main():
                            io.setup(PIR_PIN, io.IN)
                            turned_off = False
                            last_motion_time = time.time()
                         
                            while True:
                                if io.input(PIR_PIN):
                                    last_motion_time = time.time()
                                    sys.stdout.flush()
                                    if turned_off and time.time() > TURNON_DELAY:
                                        turned_off = False
                                        turn_on()
                                else:
                                    if not turned_off and time.time() > (last_motion_time + SHUTOFF_DELAY):
                                        turned_off = True
                                        turn_off()
                                time.sleep(.1)
                         
                        def turn_on():
                            subprocess.call("sh monitor_on.sh", shell=True)
                         
                        def turn_off():
                            subprocess.call("sh monitor_off.sh", shell=True)
                         
                        if __name__ == '__main__':
                            try:
                                main()
                            except KeyboardInterrupt:
                                io.cleanup()
                        

                        Here is the monitor_off.sh

                        #! /bin/bash
                        export DISPLAY=:0
                        xset dpms force off
                        
                        

                        And Monitor_on.sh

                        export DISPLAY=:0
                        xset dpms force on
