I have now had fun creating a BrewPi for lagering. Previously, there was an STC-1000 which has worked well. The Lagering Freezer became the guinnee pig in order to test the unit before using the BrewPi on a new brew. The project begins with the instructions from "HOWTO - Make a BrewPi Fermentation Controller For Cheap".
