Ich moechte gerne die graphische Darstellung der Temperatur aendern. Wie wechsel ich von C auf F?

Thanks in advance.

I am working on the firmware at the moment, maybe I can add this

Danke fuer's update!
Ich bin ueberrascht, dass ich der erste bin, der dieses bemerkt.
Alle Touch user in den USA/Britain sollten sich eigendlich melden.

your German sounds to good for google translate - where did you learn German?

Well, I am German. However, I do live in the States now and enjoying German products. :)
On a side note: I do not know why the country in the registrations shows Afghanistan. :confused:
I guess, I have to check my profile.
