Can not enter minus temperatures by typing the minus sign first. Need to enter the number first and put the minus sign in front of the number afterwards
The temperature can not be set under zero celsius, but living in Scandinavia this would be big improvement.
I just tried and it actually works, however you first have to enter the number and then go before the number and add the "-". So this is actually a bug when you start with the "-" that it replaces it by default value. We will check.
