Module error after updating - MMM-Pir: Pir Error detected: EINVAL: invalid argument, write

Jazz

Hi,

I’m running on a Raspberry Pi 4…

jazz@magicmirror:~ $ cat /sys/firmware/devicetree/base/model;echo
Raspberry Pi 4 Model B Rev 1.5

Please note that my account is a member of the gpio group…

I’ve had a magic mirror up for several months now. Due to the recent reports of problems being discovered with OpenSSH, I decided to do a full system update (that is, I did a ‘sudo apt update’ followed by a ‘sudo apt full-upgrade’) of the system. Note that i’m running raspbian 12…

jazz@magicmirror:~ $ cat /etc/os-release|grep -e NAME -e VERSION
PRETTY_NAME="Raspbian GNU/Linux 12 (bookworm)"
NAME="Raspbian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm

I then updated the magic mirror software (‘git pull && npm run install-mm’). I then updated my modules, including MMM-Pir (https://github.com/bugsounet/MMM-Pir) via ‘npm run update’ and ‘npm run rebuild’. Everything proceeded as expected, but afterwards when I restarted, I was presented with an error in the notifications section of the magic mirror display saying “MMM-Pir: Pir Error detected: EINVAL: invalid argument, write”.

Note that i’ve made no changes to the wiring of the PIR sensor or to the module configuration, which looks like…

{
    module: 'MMM-Pir',
    position: 'top_left',
    config: {
        debug: false,
        delay: 2 * 60 * 1000,
        mode: 10,
        displayCounter: false,
        displayBar: false,
        displayStyle: "Text",
        displayLastPresence: true,
        lastPresenceTimeFormat: "LL H:mm",
        pir_mode: 0,
        pir_gpio: 17,
        pir_reverseValue: false,
        mode6_gpio: 20,
        mode6_clearGpioValue: true,
        xrandrForceRotation: "normal",
        wrandrForceRotation: "normal",
        wrandrForceMode: "1920x1080",
        touchMode: 0
    }
}

Note that if I do a ‘pm2 logs magic-mirror’, here are some of the last entries in /home/jazz/.pm2/logs/magic-mirror-error.log…

0|magic-mi | [4347:0702/141938.410247:ERROR:gbm_wrapper.cc(74)] Failed to get fd for plane.: No such file or directory (2)

0|magic-mi | /home/jazz/MagicMirror/node_modules/electron/dist/electron exited with signal SIGINT

Anyone have any ideas on how to resolve the issue? I’ve tried changing the module ‘mode’ values to 9 and 2, but 10 seems to be the right value for my raspberry pi.

Jazz

@Jazz said in Module error after updating - MMM-Pir: Pir Error detected: EINVAL: invalid argument, write:

pir_mode: 0,

Sorry, I have forget to update ReadMe for this error
Generally happen with x64 system (Rpi 4 and Rpi 5)

Available pir_mode:
pir_mode: 0 - use onoff library (For Raspberry Pi 3b+ and 4)
pir_mode: 1 - use python script with RPI.GPIO library (For Raspberry Pi 3b+ and 4)
pir_mode: 2 - use python script with gpiozero library (For Raspberry Pi 5, not tested on other Raspberry Pi)

So, Can you try pir_mode: 1, or pir_mode: 2,

Jazz

@bugsounet Changing pir_ mode from 0 to 1 has fixed the problem :)

Thanks for your help.

Hi everyone,

I just can’t get it to work guys. Please help.

GPIO setup:
VIN - Pin2
OUT - Pin6
GND - Pin11

Configuration:
module: ‘MMM-Pir’,
position: ‘top_left’,
config: {
debug: false,
delay: 1 * 30 * 1000,
mode: 1,
displayCounter: true,
displayBar: true,
displayStyle: “SemiCircle”,
displayLastPresence: true,
lastPresenceTimeFormat: “LL H:mm”,
xrandrForceRotation: “normal”,
wrandrForceRotation: “normal”,
touchMode: 2,
pir_gpio: 17,
pir_mode: 1,

I have been playing around with all variations and have tested 3 sensors. Not sure what I’m missing.
Thank you for your support!

@Laca44 does it work outside
MagicMirror?

there are python scripts to test operation.
google search
python pir sensor test

I’m a newbie and this helped a lot! Thank you!

sdetweil

@Laca44 were you able to solve the problem?

@sdetweil Yes it helped in resolving the issue. I still need to understand what troubleshooting actually helped.
