Add valve level to history/logbook of climate entity

Hey, when I click on the details on my radiator valve entities (of type climate) I can see the data curves: target temp, current temp and heating.

While I wasn’t able to observe any data for the latter, the other two work fine for my homematic IP setup.

Though, I really would like to the see valve level, which is reported as attribute as well as the two temperatures. Is this possible?

And for my understanding, where are the three attributes defined which are shown by default in the graph?

Thanks a lot
