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

Petal0u

Hi all,

i followed every step of this post :point_down:
@randombullet said in How I got my Magic Mirror working on a Raspberry Pi 0 (zero):

I’ve been working on this for a little bit and I’m sorry for all the incoming questions and posts on here.

On sudo npm install, I get npm ERR! code EPEERINVALID.

I’ve tried googling some answers but I’m not confident enough to figure this out. Also I’m writing the steps in a more linear way to make more sense of it this is what I have so far and I’d like some input so that I can help other people.

Step 2
My Jessie Lite didn’t allow me to create files for some reason. I posted on reddit here.

Anyways the way of going around this is to put in a “wpa_supplicant.conf” file into your SD card and put the following in:

network={
ssid=”YOUR_WIFI”
psk=”WIFI_PASSWORD”
}

This is what I have so far. Please look over this. Thanks in advanced!

everything works fine exept the pir sensor. :smirk:
I’ve a python script to test the pir sensor. Motions are detected but my mirror still turned off.

does anybody have an idea ? :expressionless:

Pir sensor module works fine. Screen wakes up.
I stil have nothing on screen, no smart mirror.

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

Cheers,

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. :-(

Mikgabo

@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

@Mikgabo

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
  -o, --off                         Power off the display
  -m, --modes=GROUP                 Get supported modes for GROUP (CEA, DMT)
  -M, --monitor                     Monitor HDMI events
  -s, --status                      Get HDMI status
  -a, --audio                       Get supported audio information
  -d, --dumpedid          Dump EDID information to file
  -j, --json                        Use JSON format for --modes output
  -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

Mikgabo

@NoNameRo Thanks! I’ll give it a try.

@NoNameRo

Thanks SOO much!!! Got er working now. I really appreciate your help in the matter!!!

Cheers,
Mike
