    HDMI CEC

    using https://github.com/Pulse-Eight/libcec indeed works fine, I use the same thing on my pi. It is not yet connected to the PIR sensor, so I cannot provide a out-of-the-box solution for you.
    One thing you should keep in mind is the “boot delay” the screen needs when you resume out of standby.

    Thank you dude!
    Maybe I can get Pulse-Eight running somewhere today. Will hook it up to my PIR as soon as possible :D

    The delay is fine for me, better then “no signal” ;)

      Do all HDMI devices respond to these commands or only particular models? If the latter, can you recommend one? Cheers, Steve

        I followed these few steps: http://constey.de/2014/10/fernseher-ueber-hdmi-per-raspberry-pi-steuern-cec/
        I know the instructions are in German, but the commands should be enough.

        I would say most “smart” screens do, but I don’t have a list of screens which support this. Sorry

          @yawns I think I tried it now for about 5hrs, but Im not able to build the CEC stuff (looks like the how-to is for an older version). Unfortunatly I need some more time to fix those build bugs :(

            I can’t tell if my approach would work on the MM-image, but on a RasPi with latest Jessie-image it seems pretty easy:
            sudo apt-get install cec-utils

            sudo usermod -a -G video [put user triggering the following commands here]

            To turn monitor on:
            echo on 0 | cec-client -s -d 1
            To turn it off:
            echo standby 0 | cec-client -s -d 1

            Of course it depends on the time your specific monitor will need to come out of deep stand-by. Mine takes 12 secs to respond :-(
            But I’ve seen monitors only needing 2 secs…

                I’ve had success gutting an old IBM Laptop for its LCD. I ordered this driver board kit off of EBAY and it works great. The ribbon cable is a bit short, but I’ll worry about that when I finally get around to installing the LCD into a mirror / picture frame. My local recycling depot always seems to have a bunch of old laptops being disposed of. I recommend emailing the driver board seller to make sure you get the right one to work with your LCD.

                  Great idea! Came here for this information and so far i see:

                  • Asus
                  • NOT Spectre
                  • Buy cheap x from thrift stores

                  I’m looking to build a mirror that is 28” x 36”. Given LCD prices, it seems like i should buy a TV. Any recommendations on either direction? Looking for a something thin, easy to work with - ie remove bezel, etc, has ports on the right side of display.

                    Thanks for all the advice and after looking around, I feel that the CEC option is the best one but, unfortunately, is out of my budget. I’ve stumbled across this suggestion which looks like a neat (and cheaper way of getting the same effect.

                    https://forum.magicmirror.builders/topic/2077/pir-sensor-sleep-lcd-monitor

                    What’s everyone’s thoughts on it? If it wouldn’t work then could you instead connect to the remote control IR input and force standby that way?
