PIR sensor to turn monitor off. Nothing works :(

[elleclouds]

@rafhtl I was able to achieve this but my monitor stays off after a while and doesn’t come back on. Earlier in the thread I was suggested to just put the monitor to sleep but the code I used came back with errors. I needed help with those lines.

@elleclouds ok
You need to acces the monitor’s menu
I think I read you dont have a remote?
You need to access the energy saving menu
It musdt be something simple as that

@rafhtl can’t access it. Stripped down the monitor in my build a while ago

wait, the code comes back with errors?

do us a favor.

DISABLE the pir-sensor module for this test.

SSH into the mirror when you’re gonna be away for a couple hours.

type: vcgencmd display_power 0 - Monitor should shut off.

Go do whatever for a while. Come back,

SSH back into the mirror, and type vcgencmd display_power 1 Monitor should power on.

If the monitor doesn’t power back up, there’s a good chance the monitor isn’t good for your use. If it does, then we need to look at how it’s interfacing with the PIR Sensor module.

@BKeyport commands that work on pi3, do not work on pi4… many struggling with things that worked, but don’t now

@sdetweil True - however these commands do work the same as they did before. (Assuming you’re using the HDMI 0 plug closest to the power supply anyway)
