Help! Probem using PIR Sensor on raspberry pi zero to turn on/off screen

@Mikgabo said in Help! Probem using PIR Sensor on raspberry pi zero to turn on/off screen:

My major problem is getting my PIR sensor to function properly. I have it working properly on a pi3 but not the zero.
What code did u use for your PIR?

for the Pi Zero use the PIR script from @cruunnerr --> point 2.2 Using PIR script

maybe this is helpful

The very important thing is, that your monitor supports HDMI-CEC or ARC. Otherwise u will not be able to turn it on or off via HDMI.
To reassure you, most monitors do this ;)
To check if it works just go into terminal via ssh and type:

sudo tvservice -o to turn off
sudo tvservice -p to turn on

edit: for some monitors the following commands work better. Please use them if your monitor needs it:

vcgencmd display_power 0 to turn off
vcgencmd display_power 1 to turn on

@NoNameRo Hi!

Thanks for the reply :)
I’ll give it a try later when the kids are sleeping.

FYI this is how i’m trying to configure my PIR https://www.magicmirrorcentral.com/pir-sensor-raspberry-pi-magic-mirror/
If you have a soluton that currently works on your Pi ZERO please pass it on.

Thanks,
Mike

To test if it works, you should enter it correctly

to turn off the screen

sudo tvservice -o
or
vcgencmd display_power 0

to turn on the screen

sudo tvservice -p
or
vcgencmd display_power 1

please follow the instructions under 2.2 Using PIR-Script, then your PIR will work too

@NoNameRo Thanks! I’ll give it a try.
