I've been looking into fermentation temperature control and came across BrewPi. Even though I live in Southern California, I'd like to be able to keep some brews at optimal temperature -- the house does get somewhat cold during the winter. Relatively, at least ;)
Can I use the this BrewPi setup with a Fermwrap without a fermentation chamber? I can probably put it into a small room where heat loss will be minimal. I already have a kegerator, so having another similar contraption isn't feasible right now in terms of space or appearance.
