I never had any problems with Thread that couldn’t be fixed by pulling batteries from a crashed Ikea device and I have very little interest in how the protocol works.

Automatic updates in Home Assistant are disabled by default for a reason. It’s not an ultra polished, safe corporate environment for non technical wives and children.

Which sensor? Battery powered temp/humidity sensor or USB-C powered air quality monitor? I’m asking because the battery powered one is known to be bad. They disconnect and refuse to connect again until their batteries are pulled for ~10 seconds. It’s a device problem, not Thread problem.
