EVE Degree is recently being selling on apple store here. The only things which attracted me is the large temperature display. Its homekit compatibility is not as important right now because both of the heater and the dehumidifier requires manual power up.
The size of EVE Degree is a lot smaller than EVE motion. It is even smaller than the HUE motion device.
I need to figure out how can I auto triggering both the heater and dehumidifier in order to make the EVE Degree a bit useful.
Right now it is just a temperature reader until I found the solution.
EVE Degree is expensive, though.
