PIR problem RPi 4B, Bullseye 64 bit

[wyovino]

I have a python program that turns the monitor off and on. It works, but not when Magic Mirror is running. I’ve tried every trick I’ve found but nothing works. I’m using “sudo xrandr --output HDMI-2 --off” to turn it off and “sudo xrandr --output HDMI-2 --auto” to turn it on. Tvservice doesn’t work in Bullseye.

Interestingly, if I stop Magic Mirror with “pm2 stop mm” from an ssh session, start my python program, and then restart Magic Mirror (“pm2 start mm”) the PIR program works as expected.

Where is MagicMirror started and is there a way to insert my program start command before MM starts? Starting my program in crontab @reboot doesn’t work.

@wyovino pm2 launches a script in the
MagicMirror/installers/mm.sh

pm2 info (the pm2 app name, as shown by pm2 status)

for example
pm2 info MagicMirror
or
pm2 info 0 (if its the 1st created app in the list)

[sdetweil]

@wyovino sorry, I hit reject by accident, please resubmit

are you using pm2? or the manual install startup process editing a service?

did you use my install script? or the manual install?

[wyovino]

@sdetweil I don’t know why but my previous reply was rejected. I added my script to the mm.sh script but I believe that is legacy code that doesn’t get executed. This is the first line of that file:" # This file is still here to keep PM2 working on older installations."

Any suggestions would be appreciated.

[sdetweil]

@wyovino see my previous reply, I hit reject accidentally. ( I review all posts for members with reputation below 2, to keep out all the scammers, and porn posts)

anyhow, my install script uses that file with pm2 to launch MM.

so, as you are using mm as the name, the file is

~/MagicMirror/mm.sh

again, pm2 status

will show you the apps managed
pm2 info (the name or line number) will show you the detail, including the name of the thing launched

[wyovino]

@sdetweil I followed the instructions for the manual install and I’m using pm2. MagicMirror is working as expected, but I just can’t get my python script which stops and starts the monitor based on input from a PIR sensor to work unless I stop Magic Mirror, start my program, and then restart MagicMirror.

At this point I’m thinking of starting from scratch with the previous version of Raspberry Pi OS (Buster) which I believe works with a PIR module for Magic Mirror. That uses TVservice which does not work with Bullseye.

@wyovino

show me the output of

pm2 status

[wyovino]

@sdetweil
$ pm2 status

│ id │ name  │ mode     │ ↺   │ status    │ cpu     │ memory   
│ 0  │ mm    │ fork     │ 0   │ online    │ 0%       │ 2.8mb

[sdetweil]

@wyovino said in PIR problem RPi 4B, Bullseye 64 bit:

│ 0 │ mm

so the managed app name is mm
and the managed app number is 0

so, now, show me the output of pm2 info 0, or pm2 info mm

from my system

I tried putting the command in /home/pi/mm.sh but it’s not working.

[sdetweil]

@wyovino maybe python needs some path info, env setup

[wyovino]

@sdetweil It’s running the program but the commands to control the monitor are ignored, The program is logging the activity. Here is the scenario that works:

Boot the Pi
Connect via SSH and issue command “pm2 stop mm”
Connect directly to the Pi using a connected keyboard and start my PIR program, then enter “pm2 start mm”

This works but is obviously inconvenient as I need to have a keyboard connected to the Magic Mirror. I’m going to see if I can run my program from crontab under the “pi” account. Maybe that’s the issue.

[sdetweil]

@wyovino what do the pm2 logs show?

stop mm via pm2
pm2 stop all
pm2 flush – clear old logs

pm2 start 0

pm2 logs --lines=50

[wyovino]

@sdetweil I appreciate your help in this as it’s obvious this is an environmental issue, not a Magic Mirror issue.

[sdetweil]

@wyovino I don’t see anything related to python there

to get rid of the mesa errors, add

export ELRCTRON_DISABLE_GPU=1

in the mm.sh in front of the npm start

[htilburgs]

I had issues that look the same. After a system crash (defect SD card after 6 years) I could fallback on a backup, but I decided to do a fresh install wih the latest rPi OS. After that my PIR didn’t function anymore. Screen didn’t went of and back on again.

In my case the solution to put the GL driver back to legacy.

• sudo raspi-config
• advanced options
• GL driver
• Legacy

After that my Python script and the PIR worked as they should.p

Interesting. Are you using the MMM-PIR-Sensor module?

[htilburgs]

@wyovino No, I’m not using MMM-PIR.
I’ve documented it on my website, but it is in Dutch ;-)
