That is curious. A SmartThings-smartthings-CT100_Thermostat exists and the stock CT100 handler in the repository had the explicit vid (the Z-Wave Thermostat one) that was overriding it removed back in December.
The CT100 vid does include temperature measurement as a condition.
As you can see, on the face of it the CT100 should be using its own default presentation but it isn’t, it is still picking up the old one. I’m guessing it hasn’t made it into production for whatever reason.
