I've just got my first FHT80b-II controller and a bit disappointed to see it only shows the temperature the room is currently set to - not the actual current temperature of the room.

I haven't got the USB stick yet, is it possible to view the current room temperature via FHEM (or similar) (i.e. the controller reports this, but just doesn't display it) or is there no way to get the current room temperature and only know if a room is heating or not heating?
