[Fixed] Home Assistant not responding to Switch changes in tellstick duo

Configuration
1

I just upgraded to 0.110.1 from a much older version (was running Ubuntu 18.04 with Python 3.6, just upgraded to 20.04)

Most things are working okay, however my Tellstick switches no longer update Hass. Sensors are fine, so there is communication there.

They show up in the gui, and tdtool shows that telldusd is receiving the signals from the switches.
No related errors in the logs that I can see. It even says it detected the switches without issue.

Any ideas on how to troubleshoot this, or what could be wrong?

I was getting weird errors in journalctl, and because I don’t believe in being methodical I fixed it with one of the two things:

  1. Disabled App armor
  2. Added more disk to the VM (18.04 had been running fine with the 10G I gave it, but 20.04 seemed to sit at around 500M free, which I figured can’t be good)

Anyway, everything seems to be working fine now. I still have no idea what was broken.
