      ok i’ve checked and it’s not working fully.
      problem is with /usr/bin/sh /home/pi/killpir.sh

      there is no /usr/bin/sh only rsh

      edit.
      ok i’ve changed path to /bin/sh and now i get error :
      grep: pir.py: No such file or directory
      pkill: no matching criteria specified
      Try `pkill --help’ for more information.

      even if pir.py is running (i can see it in ps -ef |grep pir)

      edit ok i was able to fix it i’ve edited killpir.sh to
      sudo kill $(ps aux | grep python | grep pir.py | awk ‘{ print $2 }’)

      now it will kill process pir.py

      but problem is that even if this script (pir.py) is not running the mirror still turns on when there is movement and turns off after 30s no movement … strange

        When the pir.py isn’t running, then it isn’t this script which turns on your monitor.
        Do you have the MM-PIR module active?

        Please try to edit your rc.local and delete the autostart of the pir.py to see, if the monitor still turns on/off when there is movement.

        if not, then the pkill command isn’t working, which would confuse me, because i just tried it by myself on my mirror.
        via ssh i just entered the sudo pkill $(ps aux | grep python pir.py | awk '{ print $2 }')" command and my pir wasn’t working.


        and to your first problem, which u solved by yourself…

        u could also try to edit the killpir.py to this:

        #!/bin/bash
        sudo pkill $(ps aux | grep python pir.py | awk '{ print $2 }')
        

        then u should be able to just let your cronjob look like:
        0 21 * * * root /home/pi/killpir.sh

            i’ve removed line from rc.local and mirror is still working as should (turn on when there is movement and turn off after 30s as set up in MMM-PIR module)

              Was the MMM-PIR sensor module active while you tried the script of 2.2? You will have to disable the module. Then you create and load the scripts and create the cronjob. If you don’t disable the MMM-PIR module then it will keep waking up the screen even if you disabled the pir.py script.

              Please excuse me if that’s what you did and I just got it wrong.

                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
                      #
