I am actually not sure if this is a breaking change, can you tell me @bdraco ?

Before

After

Maybe HA interpolate "4.1 Tb" to "4.1", because HA is showing a graph, and not a line (like the sun sensor), and good values in the graph.

Nice values in the "history" panel too.

If not breaking change, should be added to 0.109.X

@Quentame I'd class it as a bugfix to fix the missing units on disk space used.

Ok, changing
