BrewZilla Gen4 Temperature Control and Programming Tips and Tricks
The BrewZilla Gen4 has a list of features that make it unique from other All-In-One brew units. Those are covered here: https://www.homebrewfinds.com/hands-on-review-brewzilla/. But there are some significant functions and features that need a deeper look to fully understand them. In this write-up, I will focus on temperature control as well as programming tips to automate your brew day.
Temperature
When I first got the BrewZilla Gen 4 with the Bluetooth temperature probe, I didn’t understand it. I thought it just gave me the option to use either the temperature sensor in the base of the unit (like most other AIO units), or the Bluetooth as a wireless probe sitting in the grain bed. But that’s not it. It uses both sensors SIMULTANEOUSLY. No mass market controller does that- AIO or otherwise. To get that kind of functionality you’re talking a custom-built controller running some of the advanced brew control software.

Kegland’s implementation of dual-probe control is very simple and straightforward in the BrewZilla. To best understand how this works, you need to think of your system in its recirculation loop. The wort drains down from the grain bed to the bottom, gets heated by the elements in the base, then gets sucked into the pump to get dumped on top of the grain again. The Bluetooth probe sits in the middle of the grain bed, and base sensor sits in the small volume of wort getting heated by the elements. When you’re at a steady target temperature, both of these probes should read about the same, as you ideally have uniform temperature throughout your system.
