      @strawberry-3.141 Ok, I’ll give it a try. Tomorrow morning, I will test again. Thx!

      WORST case senario is you install a screen saver program and disable it… period. 🙂

        @cowboysdude 1st thx for taking time to reply. much appriciated! the PIR is ok but as it needs to get hidden somewhere, etc it’s less convinent. Yes you are right, the solution depends on my personnal need… i just need a way to switch on MM when i am in front of it BUT also completly switch off the monitor when nothing detected and not only the MM.
        oh great, i will check @strawberry-3-141 module for sure!
        @IngmarSwart also designed a solution with motion detection with a Picam behind the glass which seems to be nice to. i let you check it if interest…

        by the way, do i have to remove Paviro module to install your one?
        i couldn’t find @strawberry-3-141 module… can you pls forward me the link?

          @done propably everything is working for you guys and you can just see the screensaver, be sure to disable the screensaver

          Negative. The screensaver has been disabled but the motiondetection module isn’t working. I gave the Facial Recognition module a try, but with the camera behind the glass, there isn’t enough light to train the system to recognize anyone.

          At this point, I’m considering downgrading my chromium to something without the new security “features”.

            I’m still working this problem. To help with @paphko 's concern about processor utilization, I finally figured out how and where to put a delay in the main image comparison loop. @alexyak is using the RequestAnimationFrame feature to run the comparison as fast as the browser can render the UI.

            If you wish to include a delay, modify your motion.js file’s main function to read as such:

            function main(frequency) {
            	render();
            
            	if(rendering == true) {
            		setTimeout(function() {
            			raf(main.bind(this));
            		}, 500);
            	}
            }
            

            That last number (the 500) is the milliseconds between each image comparison. I think half a second between comparisons is enough to keep the CPU usage down and the effectiveness up.

              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 😃

                    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! 😃

                    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
