While trying to drill down, how to activate my BMP390 sensor in Signal K,
i checked syslog ("journalctl -r") and found it spammed with these events:

Ulsi,
I think this is the same issue I found with lgpio.py used by the openplotter-i2c-read service. The following link in that thread is I believe the best solution. There also is another solution earlier in the thread. Give it a try I think it will solve your openplotter-i2c-read service error.

Many thanks for the suggestion.
I followed the instructions and created a file in /etc/profile.d for the export command, but
after reboot situation was the same and couple second the message is logged.
Hi Jay_cd33,
and i read the thread you linked from the beginning and found your solution of commenting
line 504 where the file is opened.
For now it works for me as well, also it is a bit dirty solution.
I guess i will dig a bit more in direction i got from Raspberry Forum.
Maybe the issue is that the Openplotter image is more for Rpi4 and before, and not so much for Rpi5 (yet).
