I am using Bugsounet’s version

Thanks for the help

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,

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

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

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. :)

I installed it with MMM-Pir-Sensor-light and changed the code to use wayland,
to toggle the display on Pi5 this is working on a fresh OS install

WAYLAND_DISPLAY=“wayland-1” wlr-randr --output HDMI-A-1 --off
WAYLAND_DISPLAY=“wayland-1” wlr-randr --output HDMI-A-1 --on

possible outputs HDMI-A-1 (the one right next to usb-c), HDMI-A-2

If you monitor turns back on by itself after ~10 secs add “vc4.force_hotplug=1”(1=hmdi1 / 2=hdmi2 / 3=both) to the end of your /boot/firmware/cmdline.txt without creating a new line

All I did was change the command in activate and deactivate display function in the node_helper.js and added the cmdline parameter (dont forget to reboot)

Thanks for your patience, this is what i get.
