Issues with MMM-PIR

[ChanceTime]

Is anyone able to get MMM-PIR successfully running on Bookworm? Feels like every option I’ve tried to turn my screen on and off after the PIR senses movement has been a struggle with no results. I’ve confirmed with tests that my sensor is working, but all the old ways to trigger the display on-off behaviour seem to not be running. I’m on a Pi4 running 12 with Wayland.

Unfortunately I can’t go back to 11 because 10 worked like a dream, and 11 for some reason i could never successfully troubleshoot would refuse to load a taskbar in. Hardware seems to be working fine again in 12…

I can post my config if it helps. Thanks for the hard work, bugsounet. :)

@ChanceTime bookworm on pi4 or 5 uses a different window manager, Wayland, and requires different commands

you can go back to xorg by using the raspi-config command

Hi

I have had MMM-Pir module running perfectly for months. When I updated my RPi 3B+ to the latest updates this week the module produce the same error message

Pir Error Detected: EINVAL: invalid argument, write

I have tried reinstalling the module but no luck.

Any help greatly appreciated

Thanks

@diccon which MMM-PIR?

[bugsounet]

Hi, check pir_mode feature in readme readme

by default pir_mode is on mode 0
With pi 4 and pi 5, you can have EINVAL: invalid argument, write error
In this case
you have to use with pi 4: pir_mode: 1,
with pi 5 pir_mode: 2,

Thanks for the help

@bugsounet thank you changing to pir_mode 1 fixed the problem. Just for awareness I am running on a RPi 3 B+ Rev 1.3 hence why I didn’t do this sooner.
