Thanks for helping!. I like the ideas.
After some searching i found something interesting!.

At this page they have a tutorial for using HDMI-CEC.
Following this tutorial it was exactly what i was looking for.

Except the time the TV needs to start it works like a champ :)

Hi all,

So i finished my first project and want to go bigger. Let’s say BIG!.
I have a spare Samsung 46" TV (UE46ES6340)

With my first project i managed to get the screen to go into sleep mode and wake up with a PIR sensor.
This big boy doesn’t want that.

I know, ofcourse it’s a tv. So when there is no signal it just says “There is no signal”
Is there, or does anyone know of a way, to put the TV into stand-by if the signal drops and turn it back on when there is signal on the HDMI port (it has CEC+ support)

Cheerz :)

@sdetweil
Defenitly not.
Although it’s weird at the end it’s working.

Going to test this a couple of days to see if it stays this way…

@sdetweil

So. I came home after work frustrated that it didn’t work.
After connecting another HDMI cable everything is working as expected 🙄.

I had a MicroHDMI to HDMI convertor and a HDMI cable after that.

I ordered a Micro to HDMI so i could get rid of the convertor.

Strange enough it is working with the convertor cable.

@sdetweil

Ah i see.
But on the other hand: It goes into stand-by so the front light turns orange, and the screen goes all black (no backlight).

I’ve found it and uploaded it. Not huge but for a 24" it’s fine.

I’m running a 8GB PI4.
I’ve installed NewPIR and configured it like this:

		{
			module: 'MMM-NewPIR',
			position: 'top_left',
			configDeepMerge: true,
			config: {
				screen: {
					delay: 20000,
					turnOffDisplay: true,
					mode: 1,
						},
				pir: {
					gpio: 17
				}, 
			}
		},

Strange enough it’s working now on another monitor. No sleepy “No Signal” text on screen but just a monitor turning in stand-by.
It’s not a new monitor --> Fujitsu L20T-4 connected with DVI

I can’t get my hands on it…

@c1olli

That might be nice.
But how about the startup?. Do you get the ugly brand boot screen first?. How longt to fire up?

@sdetweil

So weird. I can’t imagine that a crontab can do it and the same line in a .sh not.
That’s bothering me. To be continued.

Saw another module im gonna try tomorrow: MMM-NewPIR

@sdetweil

Ahh so. But doesn’t the backlight stay on all nigjt?. Not very energy efficiënt 😋
