I get an error when i start the script.

What could be the problem ?

Not a great error message to be fair, but it looks like you haven't specified which module you wish to use in your ini file. Have you read the README?

I changed it to 'MODULE = gpio', now i get a diffrent error. I use the GPIO pins direct.

Traceback (most recent call last): File "./mqtt-gpio-monitor.py", line 326, in init_gpio() File "./mqtt-gpio-monitor.py", line 272, in init_gpio GPIO.setup(pin, GPIO.IN) ValueError: The channel sent is invalid on a Raspberry Pi

I changed from monitorring pin 9 and 10 to 23 and 24. Now it seems to work. i am testing with a breadboard. What volt is high for standard gpio pins ? 3,3V or 5 V ?

Anyway thanks for the fast response and for making this little script available.

3,3V
