Yeah, I think it’s the default which it uses if you assign the Temperature type - even if I don’t realy understand why it uses the °C as the default in your case and not the %unit% then…

You are right - good find with the digits.
You generally can use Math methods in YAML for example =Math.round(items.XY.state) works - sadly it won’t work here as it takes the value into account which messes up the calculation obviously.
This is the reason for me, I mostly renounce from using types or at least defining a separate stateDescription without the value symbol for calculations like %.0f - so that =Math.round(items.XY.displayState) would work.
