      What you want here is a PIR sensor, so the monitor only wakes up when there is someone around. That will help you with the electric cost and, more importantly, won’t stress your display that much. Look for “PIR sensor” here, there is plenty on modules / ways to do it, and the actual sensor is dirty cheap on Amazon. If case that helps you, this is how I did it.

        Easiest way is to use the MMM-Remote-Control module. With that, u were able to turn off and on the monitor with your phone or every other network device.

        Other options are a PIR-Sensor or a button on your mirror. There are many threads about that. Just give the search function a try ;)

          Don’t forget, you can also hook up the monitor to a PIR switch directly (check wattage allowed for the PIR switch!) or to a light/power switch or even a combination.

          I didn’t want the monitor to be in standby when I’m not home for a week, so the PIR directly controls power to the monitor to completely switch it off instead of it going to standby. And the PIR is behind a switch, too.

            Cheers for the replies everyone all is noted :)
            For now think I’ll keep searching the net for a way to have the monitor on during the day and sleep at night.
            I have found one site that shows how to do it but want to make a backup image first incase I break anything lol.
            I do like the idea of a pir. Are they easy to setup if I cannot get on with the way I’m currently looking for.
            Cheers

              For simple time based screen on & off check https://github.com/ianperrin/MMM-ModuleScheduler

                Sorry, should say you combine with the remote control module to send screen off notifications.

                  So I’ve been looking through the net and have found I can use vcgencmd display_power 0 to turn off my monitor and the same again to power 1 to turn it back on, it also explains it can be run as a cron job but I’ve never done one of them so not to sure.
                  Would it all be possible to hook up a push button switch to the gpio and have them commands somehow turn the display off and on.
                  Thanks

                    Don’t forget that the monitor will still be on, it’s just in standby, still consuming power. The Pi can’t switch the power of the monitor itself off.

                      Yeah cheers I’m aware of that, it’s just monitor uses 37w whilst on and 2w in standby so I really don’t mind it being in standby at night.
                      I think I’m going to look into mmm-remote as trying the other method using vgenmcd power makes my screensaver come back to life even though it’s Been disabled for the last 8 months.
                      Is there any tutorials anywhere in setting up mmm-schedule and mmm-remote.
                      Cheers all

                        Ok so after trying various ways to get my monitor to turn off I have still been unsuccessful.
                        What I am trying now is with a webcam.
                        I found in my box of computer bits a Microsoft lifecam hd 3000.
                        After a little Google research I can confirm the webcam works with the pi using motion software.
                        I also found a site explaining how I can add a start and and event on detection so I set vgencmd display_power 1 as start event and vgencmd display_power 0 as end event but still no luck it just keeps display on but if I enter the command in terminal my display turns on/off as it should.
                        Am I going about this in the most awkward way or is there a simple way to get the monitor to sleep using the usb webcam.
                        Thanks in advance
