      Hi everyone,

      I’ve recently started building a MagicMirror and so far i like it a lot.
      Yesterday i ordered a HC-SR501 PIR Sensor and tried to install it.

      This is were the problems started:

      I’ve tried some modules but couldn’t get it to work.
      I’ve connected my SR501 as followed:

      • PIN4 - 5V
      • PIN11 - Motion (GPIO17)
      • PIN6 - GRND

      Is there a 2021 tutorial that can direct me in the right direction?.

      Before anyone asks 😉 . I’m trying for about 5 hours now and used the search box at the top 🙂

        @mdlefevere does it work outside mm?

        lots of internet articles with python code to read pir and say something

        the modules generally run some python code under the covers

          I’m not yet that good with Python, so some parts are a bit hard to understand.
          I’ve seen a couple of modules/posts over here and gave them a shot.

          One was working half. Screen turns of but no way to get it back on.
          This was: MMM-Pir-Sensor

          Just found a dutch how-to: here so i will give this a shot.

            off is easy, PIR doesn’t report , so nobody there, by default, so turn off…

            make sure u have ssh enabled, so u can get in from your PC and turn display back on…

            put the sensor is not reporting, or the module config isn’t looking at the right GPIO pin .

            make it work outside MM… then it will be better

              Alright i got i working with this guide.

              The only thing i’m now facing is, and i can’t understand this, that i get the message “Cable not connected” on my display.

              When i was using it in crontab with “vcgencmd display_power 0” (timebased) it put the monitor in sleep mode and the led’s of the monitor turned off.
              Now when using it in a .sh command the monitor stays on with this message.

              Do you have any idea?

                @mdlefevere well, when u ran in cron, you ran as root

                in your script do you do

                sudo vcgencmd display_power 0

                  No i don’t
                  But i tried it already and didn’t make a difference.

                  Also if i sudo su and then use vcgencmd display_power 0 it’s not sleeping.

                      Hmm alright.
                      So do you have a “workaround”?. How do you handle this?. I just want the screen to be not on all day long when i’m just home for a couple of hours
