LG C2 Monitor & Aqara FP2 automation concept

Hi!

So I'm using an LG C2 42" TV as a monitor for my PC. In the same room there's a FP2 motion sensor with two zones defined:

• Presence 2 = in front of the PC
• Presence 3 = rest of the room

Since the TV does not have a "wakeup on signal" function and my PCs sleep/standby behaviour is extremely unreliable I want to use the motion sensor to conrol the screen.

I already have the presence states in ha and managed to get screen on/off and power on/off to work.

Now my question is how to go about automating it all: I'd like the screen to blank(screen off) as soon as nobody is in the room and resume(screen on) when I return. This could be instantly because there is little delay for resuming and the FP2 seems quite fast at changing the states as well. That on its own seems manageable at my experience level :)

The tricky part: I also want the TV to power down if there is nobody in the room for x minutes but only power up again if somebody is in front of the pc.

Could you give me some pointers on how to go about it? The more elaborate the better but I'm mostly interested in the approach you would take (and struggle from there...).

Thx!
