The log-spam is a known quirk, but can easily mask the actual issue at play.
As a debugging step, I’d be tempted to disable the sensor so you can see if there are any other issues happening.

Given I can see the Connected Successfully line, I’m shocked that it’s not showing in Connected in HomeAssistant.
Nb: We’ve issued a PR here, which should fix the log spam
