p1_exporter's Issues

error: EOF

Hello!

After having used the exporter for 3 hours it suddenly stopped updating the values. stderr was showing msg=EOF so I restarted the executable. But within two days it happened again.

Situation:
Ubuntu 18.04 armhf on a raspberry 2 with the sole purpose of reading out the values of my DSMR

Output from the exporter shows:

What can I do to help debug this?

edit: I wrote a simple workaround in my systemd unit so no rush :)
