The batch was frozen solid.
Set a low limit on the beer probe. Below your floor, cooling goes off and an alert tells you which vessel needs attention.
Four fermenters. One controller.
Every fermenter on one controller. Keep the lager from freezing.
Heat, cool or glycol. Profiles advance by themselves, even when the garage Wi-Fi drops.
LOCAL Profile runs on the controller.

Concept
Control Freak Brew, brought to you by Control Freak
Sound familiar?
Less checking. More knowing.
The probe was taped to the side.
Put the probe in a thermowell to read the beer. If it comes unplugged, that vessel’s outputs go off instead of running flat out. Set a calibration offset in the app.
Still cold crashing by hand?
Save a recipe with pitch, ramp, rest and cold crash. The steps advance by themselves, even while you are away.
How it works
One plan for every batch.
Connect your vessels
Plug fridges, heat wraps or glycol pumps into the Power Hub. Put a thermowell probe in each fermenter.
Choose a saved recipe
Set the targets and timing for each vessel. Heat and cool never run at once; compressor rest keeps the fridge from short cycling.
See what happened
Every batch is logged on the controller. Check the graph instead of opening the fridge to find out what happened. Export CSV when you want your records.
What makes it different
A controller per fridge stops stacking up.
Four fermenters together
See every target, profile step and output in one place. There is also a step up for glycol cellars with more tanks.
Too far from the router?
Plug in a cable if the Wi-Fi does not reach. Profiles run on the controller, so garage Wi-Fi dropping changes nothing.
Cooling on and not getting colder
Get an alert when cooling is on but the temperature is not falling. Choose push, text, email or alarm. Phone alerts need internet.
What’s included
One kit. Four fermenters.
4thermowell probes
- Controller with Home Assistant built in
- Power Hub with 8 switched outlets
- 4 thermowell probes
- Up to 4 fermenters with heat and cool, or glycol pumps
- Saved recipes, automatic profiles and batch logs
Use your own fermentation fridges, heat wraps, fermenters and glycol equipment. Concept: design, contents, and features may change.
Home Assistant
Your cellar, part of your home.
Home Assistant built in. No subscription. See your brewery alongside the rest of your smart home, with control on your home network.
Keep the profile close to the beer.
Profiles and safety rules run on the controller. An internet outage does not stop them. Alerts reach you by push, text, email or alarm; phone alerts need internet.
Honest limits
Fermentation control has boundaries.
- No hot side. It does not run kettles, burners or heating elements.
- Nothing keeps a fridge cold in a power cut.
- It cannot tell when a relay inside your fridge’s own thermostat is stuck in the on position.
- Supported Wi-Fi hydrometers only. Not every hydrometer is supported.
