Temperatures monitoring will be added. Initially, I implemented too many metrics, so during development I limited them to a reasonable level to make them manageable, but I'll be adding more as the project matures. Thanks for the feedback!
Seems like hardware maintainers never could agree on a standard way of exposing temperature on Linux.
