Thank for raising the issue! This error is expected if the central unit or the cloud API decide to reset the connection. I will investigate more to:

• Be 100% sure we can downgrade the message from ERROR to INFO (if it's expected, you should not be worried about).
• Avoid sensors to be unavailable for a very short amount of time. This improves the user experience.

Thanks again! I'll try to go at the bottom of it!

This is partially solved in #130 where these log messages are now considered DEBUG. I'd say we can close this issue as sensors are set to "Unavailable" if the integration can't communicate with the main unit, that makes sense if there is an actual connection issue.

Anyway, I'm planning to rewrite the collector logic to solve the actual root cause, meaning keep the connection as much stable as possibile. This is going to be solved in #76 .
