      Thank you very much for the help, its really nice what you created with this module.

      I skipped the GUI as you suggested, RoomID is set, LightcontrollerV2 is in use, Presence is TRUE.

      What i changed on RPI config was :

      /boot/config.txt

      #hdmi_force_hotplug=1
      hdmi_group=2
      hdmi_mode=68
      hdmi_blanking_1
      

      I am using VGA Monitor with HDMI to VGA adapter.

      Setting “presence” to true gives me a black screen after loading MM. Swtiching on the light in the room switches on the backlight of the monitor but does not show the content. The good thing is, with this configuration there is no power consumption of the lcd any more.

      Using VNC i can see the magic mirror, so i think its a “screensaver” issue.

      next thing i am trying is

      sudo apt-get install xscreensaver
      

      There was a hint that it is possible to disable the screensaver with this tool.

      thanks for the help

        OK it seems that it is not a screensaver issue. I fully disabled it and the content of the magic mirror is not coming back. its just the backlight of the LCD that is getting switched on and off. any Idea?

          @bobbythemoh This sounds like you use some kind of other „screensaver“ which just displays a black screen instead of switching off the HDMI Port. I think you somehow enabled „screen blanking“.

            @bobbythemoh btw. Just blacking out the screen is not realy saving much power if the backlight is still on… You just have to install MMM-Loxone, it will switch off the HDMI signal everytime the lights go out, your monitor will handle the rest (you might check your monitors Power saving setting).

              Here is what i have observed:
              XScreensaver is installed, Screensaver is disabled.
              Rebooting the magic mirror with presence ON and light in the room on gives the magic mirror as it should be.
              Leaving the magic mirror in this state (and also the light in the room) does not lead to screensaver, the picture stays as it is.
              Switching off the light in the room also blacks out the monitor, power consumption goes down to 5W also without “#hdmi_blanking_1” but here is the issue:
              Switching on the light in the room after blacked out monitor brings the monitor backlight and the power consumption back but not the UI.

              With VNC i can see the UI, moving the mouse does not bring the UI back on the direct connected monitor.

              Any idea?

                @bobbythemoh I guess you have some sort of other “power saving” feature activated I am not familiar with. MMM-Loxone directly toggles the HDMI output on or off. It isn’t displaying a black view on top of the screen.

                Please verify your /boot/config.txt!
                In one ofyour posts you wrote hdmi_blanking_1 but it should be hdmi_blanking=1.

                  OK you were right, i changed it but there is no change in the behaviour. The Monitor remains without video signal just with backlight if i switch the light in the room on. Do you have any hint for me what i can check?

                    @bobbythemoh Did you reboot after correcting the option?

                      @bobbythemoh You may also try to uninstall xscreensaver

                        There is indeed some very weird issue going on with the HDMI and screen saver/blanking as I reported here. It started after I updated my kernel (from 4.9.80) & what else came with it. Out of curiosity, what is your OS version?
