    See my previous posting:

    Probably the cause is some voltage / EMI feedback, likely due to the wires and switches. Try to switch on/off some lights and electrical devices and see the result!
    To correct this condition, use a combination of current limiting, filtering and shielding.
    ;-)

    Did you read the link?
    https://www.raspberrypi.org/forums/viewtopic.php?t=53548

    Try following:

    • Reduce the cable length to the switch.
    • Detect either only the rising (GPIO.RISING) or falling event.
    • Use bouncetime in ms (minimum time between two callbacks in milliseconds (intermediate events will be ignored))
    • Use a capacitor, see folowing example.

      Hi,
      after I install the module and type “pm2 restart mm” there is just a white screen. No UI loaded. Any idea?

        @All, sry for the lait answer, I followed all your guides, but I can´t solve the problem. I have to use another power circuit.

        @cruunnerr, same here, you have to restart your pi. After the video starts for the first time, the bug is there. You can only reload mm when the video never starts in the same session.

          Version mismatch from what?
          Does someone know how to fix this?

              Thanks for the link. I tried but the error is still there.
              One thing changed.
              Before:
              Error: Module version mismatch. Expected 49, got 46
              Now:
              Error: Module version mismatch. Expected 50, got 46

                  Dear community,

                  how could i implement following scenario.

                  Connect a button to the MM and switch monitor on and off with it?

                  Issues With MMM-WatchDog known?
