Well, my first fermentation is under way with the Huzzah BrewPiLess. So far so good, except that my 25˚F ramp over 18 hours seems to be faster than the beer can adjust. Is there any way to allow a greater delta between the chamber temperature and the beer temp? It isn't really a big deal though, as this is an understandably ridiculous ramp.
What I see in you screenshot is that you switch to beer profile starting at 70F from fridge constant mode set to 25F.
When the beer profile started, it set the temperature to 70F. This is expected. If you want slow ramping, you should use beer profile like this.
Start from 65F ( 25F is your fridge temperature, not beer temperature).
Ramp to 70F in X day. You just specify the time you want, and the beer profile will calculate the increment and increase the temperature automatically.
