Access GPIO on RPI

[mapeje]

Thanks for a great software! I would like to add sensors to the GPIO (I2C MPU-9250, INA219, One-wire etc.). I tried to add the i2c-reader but I get error messages.
I also tried to re-install SignalK by uninstall in Cockpit, but it did not removed my old data.

Difficult to comment on the I2C issues without more information.

Removing the container app doesn't delete the data. That's standard practice for any Debian package. If you want to nuke the data, you need to do it manually after you've uninstalled the app:

sudo rm -rf /var/lib/container-apps/marine-signalk-server-container
