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

@Petal0u did u ever get to solve the problem? I’m currently in the same boat.

Have you disabled screensaver? That can cause the screen to remain blank.

Easiest way is to install xscreensaver then disable it from the desktop (yes this seems counterintuitive but it works)

Hey! Thanks for getting back to me.
My MM works pretty well, can’t get MMM stock to work though.
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?

Thanks,
Mike

If I remember correctly, that module’s API is no longer working, thus, killing the module. :-(

@Mykle1 Good day!

That’s interesting, I have MMM stock working on my Pi3. I am running an older version of Jessie though.
For you know of any stock ticker that would work on Pi Zero?

Thanks,
Mike

Obviously, I am mistaken then, and I apologize for an old man’s faulty memory. :-/

I don’t know if this is what you are looking for or if it works
on a Pi zero

@Mykle1 Many thanks, I’ll give it a try!

I have a few more avenues to explore I respect to the PIR sensor and will report back if successful.

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.

Hi, So I placed this command sudo tvservice -o to turn offi in terminal and this is the result…any feedback?

pi@MagicMirror:~ $ sudo tvservice -o to turn off
[E] Unrecognized argument -- 'to'
Usage: tvservice [OPTION]...
  -p, --preferred                   Power on HDMI with preferred settings
  -e, --explicit="GROUP MODE DRIVE" Power on HDMI with explicit GROUP (CEA, DMT, CEA_3D_SBS, CEA_3D_TB, CEA_3D_FP, CEA_3D_FS)
                                      MODE (see --modes) and DRIVE (HDMI, DVI)
  -t, --ntsc                        Use NTSC frequency for HDMI mode (e.g. 59.94Hz rather than 60Hz)
  -c, --sdtvon="MODE ASPECT [P]"    Power on SDTV with MODE (PAL or NTSC) and ASPECT (4:3 14:9 or 16:9) Add P for progressive

  -n, --name                        Print the device ID from EDID
  -h, --help                        Print this information

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

@Mikgabo
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.
