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 also us ASUS monitors… have had great luck with them!! They seem to stand up to the use!

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.

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?
