      Thx @bhepler
      this helped to reduce my temperature from 80 °C to 50-60 °C.
      Maybe the 80 °C even caused the wake up problem? :)

      Anyway, I think I’ll try the voice activation module tomorrow.
      Somehow it’s even very sweet to say “Mirror, Mirror on the wall. Wake up!”.

        That is the reason why my screen doesn’t switch on after a couple of hrs switched off.
        Any idea what the cause of unavailable tvservice is?

        Testwise i used the scripts reported here before. They where called if a PIR detects motion or no motion.

          So here i found a workaround. Maybe it fixes the issue but let’s see. I just modified my test script and need to see it the next hrs/days

            Hi,

            for all the people here I wrote it more cleary :D

            i had big problems by switching off my screen with the PIR or another module with camera. The problem was not the module itself it is a firmware problem of the PI. I could see the same problem outside of MagicMirror as well by trying different things.

            Reported also here:
            https://github.com/raspberrypi/linux/issues/487

            The symptom is that after a while of switching on and off the screen it remains off.

            Dmesg reports the problem:

            Switching off the screen with

            /opt/vc/bin/tvservice -o

            and on with

            /opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chat 7

            does not work reliable! The git issue tells you more about.

            The workaround is a not yet described solution inside the config.txt

            https://github.com/raspberrypi/documentation/pull/245/files

            the option “hdmi_blanking=1” is your friend in this case! :D

            Now i’m switching off the screen with

            vcgencmd display_power 0

            and on with

            vcgencmd display_power 1

            And it is working now like a charm! Did started to use it one day before this report and it is still working without any issue :)

            Honestly speaking i don’t use any MM module for switching off anymore. But maybe my discovered solution will help any other and might be a way to change the module as well.

            If you have trouble with on/off as well please check the output of dmesg. If you have the frambuffer problem you can fix it.

            My personal solution is to have the PIR state at FHEM and from FHEM i’m using a script to switch the screen. But that’s a special case and for the most people here the usage of a MM Module will be the better way.

            regards
            Dirk

                @bibi Based on that pull request, it looks like it’s in the config.txt of your Pi. So /boot/config.txt

                    @bhepler Thx! i will add this option there under HDMI hotplug as i don’t know where else to add.

                      @bhepler and @DirkS : any idea why my screen doesn’t stay off as long as no motion is detected??

                        @DirkS Thank you. Pi doesn’t die over nights :D

                        But before I mess it up:
                        Would the motion detection with the common script work or not?
                        How did you realize it? Where did you enter your new script?

                        And don’t you want to make an additional motion detector module for those who have the same problem? :)
                        I don’t see the original programmer caring to much. ;)

                        cheers
