Include temperature readings

[rallisf1]

Is your feature request related to a problem? Please describe.
Temps are just as important, hopefully not beyong the specs of this awesome app.
Not having a universal API though across OSes makes this task kinda hard.

Describe the solution you'd like

• A badge element next to the average usage one in the stats blocks.
• change the color of the badge based on temperature value e.g. green up to 60C, then yellow up to 75C, then red, or even configurable?
• Options to select sensor per block (a.k.a. device), with top and average as well
