        I dont know if this is helpful but I use

        /usr/bin/vcgencmd display_power 0
        monitor off

        /usr/bin/vcgencmd display_power 1

        monitor on

        works flawlessly
        (ssh in pi and type the commands to try them)

        r

          @rafhtl Can you give me more context on where to input this and where it should go?

            ok
            if u are using MMM-PIR-Sensor
            it should already be in the module
            please try from ssh (you have to log in to the pi) and then type
            /usr/bin/vcgencmd display_power 0
            you should first try this to see if monitor responds to command
            so first log in from a pc to your pi using putty
            r

              @rafhtl I was able to achieve this but my monitor stays off after a while and doesn’t come back on. Earlier in the thread I was suggested to just put the monitor to sleep but the code I used came back with errors. I needed help with those lines.

                You need to acces the monitor’s menu
                I think I read you dont have a remote?
                You need to access the energy saving menu
                It musdt be something simple as that

                  @rafhtl can’t access it. Stripped down the monitor in my build a while ago

                    wait, the code comes back with errors?

                    do us a favor.

                    DISABLE the pir-sensor module for this test.

                    SSH into the mirror when you’re gonna be away for a couple hours.

                    type: vcgencmd display_power 0 - Monitor should shut off.

                    Go do whatever for a while. Come back,

                    SSH back into the mirror, and type vcgencmd display_power 1 Monitor should power on.

                    If the monitor doesn’t power back up, there’s a good chance the monitor isn’t good for your use. If it does, then we need to look at how it’s interfacing with the PIR Sensor module.

                        @sdetweil True - however these commands do work the same as they did before. (Assuming you’re using the HDMI 0 plug closest to the power supply anyway)
