This is my first post on the forum, so please bear with me
I run legacy Brewpi on 3 arduino uno’s : 2 freezers and a mash tun. The freezers work perfectly to manage fermentation and I must say that Brewpi is in my humble opinion absolutely brilliant.
I’m aware that the legacy software was not designed to manage a mash profile, but rather to manage ambient temp in order to achieve a desired beer temp. Having said that I’ve been getting away with using the fridge constant mode for my mash tun, although I get an overshoot of a few degrees during mashing.
My question is whether I can adjust the heating overshoot estimator in advanced settings to try and reduce the overshoot. Obviously PID settings are irrelevant here. I have no mathematical brain, so have no idea how to approach it. If I reduce the overshoot factor, will it improve overshoot or make it worse? Also, is there any point to that, as the algorithm adjusts it automatically anyway? Should I just run the mash tun for a few hours and allow the software to improve its overshoot estimation?
