I appear to have the same problem with the 12C service not running on my RPi5 using Op4. I was hoping the detailed instructions from Aitonos would work. After implementing the instructions I checked the service.
sudo systemctl status openplotter-i2c-read.service --no-pager -l returned the following
openplotter-i2c-read.service
Loaded: loaded (/etc/systemd/system/openplotter-i2c-read.service; enabled; preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Wed 2026-04-01 13:39:51 AWST; 881ms ago

AND
systemctl show -p NRestarts --value openplotter-i2c-read.service returned the following
pi@openplotter:~ $ systemctl show -p NRestarts --value openplotter-i2c-read.service
190
pi@openplotter:~ $
My BME280 is recognised in the i2C setting on 0x68
My knowledge of Linux is very very basic so I'm now stuck. Perhaps I should try another BME280 sensor
