I get 0 to all values

[alexmuntean]

Initially I got can't divide by zero errors and then I modified the code a little bit so that it doesn't fail and I got all 3 values 0. (if the divisor is 0 leave result 0 - that's what I did)
My config was exactly as in the example.
My target temp was 25 and it was heating my home to 26 in about 4-5 hours and then again... it was a process of 24h-30h where it learned but the result was always 0.

Is this still working? did I do something wrong?
