Additional context
Power failure in the home today. Also updated HAOS to 14.2. Have rebooted S30 and HA server. Multiple restarts yield different errors.

Similar issue here less the power outage. All devices and entities are unavailable.

[PeteRager]

What version of software is on the S30? There was a similar issue with the S40 a while back where the call to Disconnect would cause an error and then the controller would be unresponsive. The solution was to update the integration to never call disconnect on the S40 and to reboot the thermostat. It is possible they've migrated this bug into an S30 firmware update.

What I'd like you to try is rebooting the the S30 (power cycle or from the menu on the panel) and see if it reconnects.

[garyak]

3.95.0146 dated 11/2024 on the 2nd gen s30. Both s30s have connected after a HA restart. It's typically a startup issue that typically occurs on the older, multi-zone s30. This behavior is new to the 2nd gen version. Errors generated at startup vary.

I should note the errors posted occurred while my backup instance of HA was running. Don't know if that would impact the connections.

[PeteRager]

It could. The S40s only allow a single connection at a time, while the S30s did not have this limitation. Both this limitation and the Disconnect issue were released simultaneously on the S40 in summer of 2023. It is possible this is now in the 11/2024 release.

Reload the integration on the S30 with the update. That will cause it to call Disconnect. If that error occurs and subsequent reconnects fail, that will confirm the hypothesis and we can fix the integration - as this will occur everytime you restart HA.

[garyak]

Integration reload on the s30 did not cause an HA log entry. Subsequent restart was error free.
