@ninjabreadman yap python_start is called by an event from the modules (script is not complete)
In the MMM-PIR-Sensor the GPIO is used. In my case I would like to use usb. So i should require node-serial port. That’s what one way I can try it.
But I also thought of doing the complete logic, like switching on/off the screen, in my python script. So the only job of the module is to call python.
