I don’t know what device type others are using.
The current device handler is reporting, it’s just not reporting the data in the correct format.
If you give me links to other nest device handlers, I can review them to check if they are following the standards or not.
And if there are no other nest device handlers, I could probably modify the current one to be compliant…
UPDATE:
This one should work:
I’ve not used it obviously, but it appears to report the temperature data correctly.
