      Make sure you run chmod - chmod +x pir.py

      Then add it to startup:

      1. run - sudo nano /etc/rc.local
      2. Add this (above the “exit 0”): python /home/pi/pir.py &
      3. Save

      Reboot to test

        @komodoteler I’ll try again once I get off work, but i know I did chmod on pir.py and I currently have it in rc.local but I don’t currently have the “&” after it’s entry. When I looked at the first post it says to put it there but doesn’t display it in the code section.

        Updated: Added the “&” still didn’t work, so I replaced the pir.py script that I was previously using and all seems to be great now. thanks again for the help.

          hey guys,

          i got another problem.
          the script is working well but the python won’t start with booting my PI.

          i don’t know how often i repeated all the steps. I am using the method 2.2 Using PIR-Script.

          i also put this line in my rc.local:

          • python /home/pi/pir.py &

          anyone got an idea what i’m doing wrong?

          EDIT:

          Sorry I have just read the post of @Magno99900. So you just created a complete new .py script? i will try this later! Thanks so far :grinning_face_with_smiling_eyes:

            I’ve just connected PIR sensor to my MM as written in step 2.1 Using PIR-Module

            everything is connected MM is started but the screen is not turning off.

            Can someone help me how can i check if PIR sensor is working and if it’s why the screen is still on ?

            i’ve changed settings to

            {
            module: ‘MMM-PIR-Sensor’,
            config: {
            powerSavingDelay: 60 // (seconds) how long the monitor will be turned on
            }
            },

              I found out that PIR sensor is ok.

              i’ve created python script from this page ( https://tutorials-raspberrypi.com/connect-and-control-raspberry-pi-motion-detector-pir/ )and found out that i’ve switched Ground and 5V. I’ve corrected them and now when i execute : sudo python pir.py i get
              There was a movement!

              before there was nothing, so i guess PIR sensor is OK

              but it’s still not working to turn off the screen.

                    @Maros

                    Glad u got it working. :)

                    So u use the script from point 2.2 ?

                    Then u could kill the pir.py at 9pm and start at 7am via cronjob. With that u were able to define each day for itself :)

                    The command to kill the pir.py script is

                    sudo pkill $(ps aux | grep python pir.py | awk '{ print $2 }')
                    

                    So the easiest way is to just edit your crontab. Try it like this:

                    1. nano killpir.sh

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

                    sudo pkill $(ps aux | grep python pir.py | awk '{ print $2 }')
                    
                    1. chmod +x killpir.sh

                    2. sudo nano /etc/crontab

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

                    0 21 * * * /usr/bin/sh /home/pi/killpir.sh
                    0 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 21    * * *   root    /usr/bin/sh /home/pi/killpir.sh
                    0 7     * * *   root    /usr/bin/python /home/pi/pir.py
                    #
                    

                    Didn’t try this solution at all, but hope/think this works :)

                    I would be glad about a feedback ;)

                        cron will start the pir.py in background. The scenario will be like:

                        Boot up magic mirror = starts pir.py via rc.local
                        at 21pm = stops pir.py via cron
                        at 7am = starts pir.py via cron

                        from this on the circle is closed and cron will repeat this every day (in background)
                        well… i think so… maybe i am wrong :/

                        When u reboot the mirror between 21pm and 7am the pir.py will be active for sure until the next 21pm will be reached … ;)

                        edit:
                        it would also be possible to implement a while-loop in the pir.py script to check if it is between 21pm and 7am.
                        But i never worked with that yet -.-

                        maybe u can get what u want here or here or here
