Hi, as it seems that you get the error when you exit the parser (?), did the parser work for you? Did you get any readings from your smart meter?

I cannot reason yet what went wrong, it works fine on my side

Hi Hans, yes I did. I installed a fresh RaspberryPi for this purpose only. I've got the same error. It turn out I had the script as root. As a systemd-service it seems to run fine. Can you confirm if these lines in the log are okay?

Your log files look OK. I have check my notes, below comment will likely solve your issue:

add root (or user which runs script) to group dialout (/etc/groups)
