      I have followed every tutorial to no avail. I’m using the MMM PIR module and followed the instructions detailed. Can anyone please help me? Is there a way in terminal I can make sure the sensor isn’t a dud?

      The monitor will not turn off

        Hi,

        i recently wrote a tutorial of how to use two of my modules to turn on/off the display with an PIR sensor.

        English

        German

        I do not have much time to support at the moment but maybe it helps…

          I have an opposite behavior after updating MM.
          After boot/reboot the mirror is on my HDMI Display but after awhile it disappears.
          The motion sensor only activates the backlight of the display but no content.
          In the webbrowser and with VNC viewer all is normal.
          If i send

          /opt/vc/bin/tvservice -p; sudo /bin/chvt 6; sudo /bin/chvt 7
          

          it comes on again on HDMI but not stays.

          Is there something like a screensaver for HDMI display active?

            Hi,
            it might be a problem with screen blanking.
            If you edit your /boot/cmdline.txt like in this description it might solve the problem.

              @wishmaster270 if you used the automated install script,m it will turn screen saver off for you if you reply yes…

              you can also run the screensaver off script part from the installation repo here
              https://github.com/sdetweil/MagicMirror_scripts

              it will figure out what system and set it off appropriately.

                  @wishmaster270 got it working with your tutorial but once the monitor goes into sleep mode, after not receiving a signal, it doesn’t turn back on unless I unplug and plug it back in.

                    @elleclouds Hi, do you see any output of the Gpio module in the log file?

                      the cmdline.txt was already ok , i really had to install xscreensaver and disable screensaver to solve my problem.
