MMM-PIR-Sensor not working with latest release - display does not turn off

@Kugelfang
Hi, I updated to 2.7.1 yesterday and also installed MMM-PIR-Sensor which works fine for me (https://youtu.be/5Cs3pCZamuM)
I am not using the Full KMS driver though
Did you follow these steps also:
Execute npm install to install the node dependencies.
Add your user (pi?) to the gpio group by executing sudo usermod -a -G gpio pi.
Execute sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt to allow turning on/off the hdmi output.
Reboot your Pi.

Yes, I did. to my best knowledge the tcservice does not work with the KMS driver.

Also looking into the details at GitHub I thought that MMM-PIR-Sensor actually uses the vcgencmd

@Kugelfang
I am really no expert at all but here is another tipp of mine:
I also use these modules to turn off my monitor:
MMM-ModuleScheduler + MMM-Remote-Control (at a certain time)
and MMM-NetworkScanner (when my phone is not connected to my WLAN)

actually I checked the pm2 logs and found loots of this messages:

does anybody know how to fix this?

@Kugelfang yes, you will need to install electron-rebuild in that module

from the MMM-PIR folder

npm install electron-rebuild

then run it to force the epoll rebuild

node_modules/.bin/electron-rebuild

[Kugelfang]

@sdetweil said in MMM-PIR-Sensor not working with latest release - display does not turn off:

node_modules/.bin/electron-rebuild

Holy SHIT that worked. I’m now using the MMM-PIR instead of the MMM-PIR-Sensor

thanks you so much!!!

EDIT:

for the record: there are two PIR modules avaliable: Initially I intended to go with MMM-PIR-Sensors as I’ve been using this in the past. Unfortunately I couldn’t get it to work with the newly installed setup. Hence I choose MMM-PIR.

Besides the suggestion from @sdetweil I also modified the displayOff.sh and displayON.sh from

tvservice -o

to

vcgencmd display_power 0

so the module works with the full KMS OpenGL driver.

@Kugelfang

Where did you change the displaOff.sh? Where can I find this?

[sdetweil]

@shgmongohh in the module folder

[shgmongohh]

@sdetweil

In which folder ?

[sdetweil]

@shgmongohh too many pir modules

https://github.com/cowboysdude/Pir-Sensor has one
https://github.com/mboskamp/MMM-PIR has one, in callbackscripts folder
