      Hi guys,
      I got my first Magic Mirror (it’s not a mirror but a display 🙂 ) ready after a huge time…

      Now as it stays in our kitchen it’s and burn power 24/7 😞

      I want to save power and looked therefore about the possibility shut the display off in time nobody is looking to it.

      I had a look to modules as MMM-PIR or MMM-PIR-Sensor and have the question if it is also possible for connected VGA-displays (connected with HDMI to VGA adapter to the Raspi)

      Is there any, I have to know, before I order the sensor and rework the placed mirror?

      Will one of these MMM-… work and save power and get the kitchen dark in the night?

      Many thanks for your help and please don’t ask if I was not able to search the WWW for answers before… I did! Maybe with wrong search words or total misunderstanding about the threads…

      Best regards, bdream

        I use MMM-PIR-Sensor successful on my mirror (i also have a VGA Monitor connected via an HDMI Adapter) to safe power.

        For your “safe power in the night” you can use another module, check MMM-ModuleScheduler (for scheduling) in combination with MMM-Remote-Control (for interaktions like monitor on/off).

          Hi AxLED, many thanks for your replay!
          I’m off next two weeks and will try it afterwards.

          I thought it will not run with VGA connection :S
          So I’m happy with this information!

          Best regards, bdream

            Hi AxLED,
            may I ask you for help please?

            I did connect a PIR to my Rpi to PIN 40 / BCM 21

            git clone https://github.com/mboskamp/MMM-PIR.git
            cd MMM-PIR
            npm install
            

            Added the the config in the verry first line within the modules chapter

            {
                    module: 'MMM-PIR',
                    position: 'top_center',
                    config: {
                            sensorPin: 21,
                            delay: 10000,
                            turnOffDisplay: true,
                            showCountdown: true,
            //                callbackScripts: ["callback.py"
                    }
            },
            
            

            Nothing happen. No countdown starts. No Disply turn off.

            Wiring was inslalled already:

            pi@MagicMirror:~ $ gpio -v
            gpio version: 2.50

            And I tried this command an a reboot:

            sudo usermod -a -G gpio pi
            

            Have you got any hints for me please?

                There are two Pir Sensor Modules. I use MMM-PIR-Sensor. Maybe this helps.

                  MMM-PIR uses the tvservice command (see MMM-PIR/callbackscripts/default for the two scripts)

                  MMM-PIR-Sensor uses the /usr/bin/vcgencmd command

                  YOU have to make sure the different approaches work

                  my TV does NOT respond to ANY command…

                    Good Info!
                    Will play next days with MMM-PIR and MMM-PIR-Sensor investigating about needed scripts vs. /usr/bin/vcgencmd command

                    If I can’t get it run mayby I will add an relais to turn off the display…

                    At the moment I have to understand the both approaches and what my display is able to handle.
                    Could be no way is possible as it’s an verry old one.

                    Cheers, bdream
