Hi, I updated mqtt-io and got this error.

Steps to reproduce
Home Assistant OS Release 2023.1.6 (raspberry3). Update MQTT-IO to 0.2.0
Somehow /dev is less than /dev/mem? c6d4059

Meh, ok, my bad, will pickup asap
Meh, ok, my bad, will pickup asap
full_access fixes it, but I am trying to see if we can add lower privileges which will still work

Thank you :) I am sitting in the dark. Lesson to backup HA before the upgrade.
@plachta11b I've shipped 0.2.1, which is not using full access... but restored the old GPIO config as well.

Could you check and see if that helps?

I still get same issue. I'm restored my backup 0.1.3 version, it works.
