MMM-PIR-Sensor Black screen..

You are correct about the BCM pin numbering beck0r, it is not the same as the actual pin number (the BCM pin numbering origins from the processor pins if I am correct).

What I advise is to forget about this module and use https://github.com/cowboysdude/Pir-Sensor instead.
I made some slight changes to this myself, because it was still not turning on the monitor correctly.

RUN apt-get update && apt-get install -y libraspberrypi-bin and replace the scripts from the above link as follows: monitor_on.sh contains only vcgencmd display_power 1 and monitor_off.sh only the line vcgencmd display_power 0. This solved my problem for every display I used so far, being HDMI, VGA and DVI displays.

How do i need to:

chmod all files: From a terminal window in your root directory:

sudo chmod +x pir.py

sudo chmod +x monitor_off.sh

sudo chmod +x monitor_on.sh

Editing pir.py

I solved the Error: Cannot find module 'onoff'- Error by removing the node_modules from the MMM-PIR-Sensor directory and reinstall them by using npm i. This time, some dependencies seem to be built in with electron, and the error disappeared.
