Already taken care of 
That screenshot is very old and showed the raw value, but I like to keep it up to give you an idea of the entities and how they appear in Home Assistant.
The code that is shipped with the Unity sensors applies what you have suggested. It uses readings from the MCU onboard internal temperature and calculates a more accurate room temperature.
I have some posts with more details on it here and here.
Here are some comparison graphs showing the Unity sensor against another off-the-shelf sensor:
Hope that helps!
