Just so I understand I'm not going mad, I paired these devices back to Home Assistant (now v2024.4.1). it took about 20 seconds to get them all back in and reporting.
I'm not that familiar with HA as they seem to have things called 'quirks'. It would appear a 'quirk' is an adapter/driver and operates much the same as an HE driver. I can't find any information relating to HA's capability to pair with the device to determine if there is something peculiar about the sensor. But the presence of the 'quirk' would suggest a mapping operation is in place, much like a required Hubitat 'driver'.
So there is really isn't any reason I can see why HE shouldn't pair other than the hub being deficient in some way.
I don't want multiple hubs, and let's be clear I've paid a lot of money for this thing; is it unreasonable to expect it to work? @bobbyD
