PIR sensor to turn monitor off. Nothing works :(

[uros76]

For those unsuccessfully trying to put the monitor to sleep and wake up with PIR, are you running MM on pi4 with Rapsberian?
I never managed to get this combination to work. Instead I did succeed with Lubuntu on pi4.

Currently I have working PIR on pi3 with Rapsberian. No issue with this one.
Just the pi4 is so different and worse to configure sleep/wakeup.

Honestly, I would resort to an out-of-MagicMirror experience. I whipped up some python code using GPIOZero to replace MMM-Buttons, for instance…

@wishmaster270 Can you help me out with this?

[rafhtl]

I dont know if this is helpful but I use

/usr/bin/vcgencmd display_power 0
monitor off

/usr/bin/vcgencmd display_power 1

monitor on

works flawlessly
(ssh in pi and type the commands to try them)

r

@rafhtl Can you give me more context on where to input this and where it should go?

[rafhtl]

ok
if u are using MMM-PIR-Sensor
it should already be in the module
please try from ssh (you have to log in to the pi) and then type
/usr/bin/vcgencmd display_power 0
you should first try this to see if monitor responds to command
so first log in from a pc to your pi using putty

@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

[elleclouds]

@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.
