Brautomat32 is a powerful brewing and fermentation controller based on the ESP32. Its focus is not simple heater switching, but precise and repeatable control of complete brewing and fermentation processes.
Brautomat32 uses its own PID controller, InnuAPID, developed specifically for home brewing systems. Instead of crude on/off switching, it applies adaptive temperature control that makes mash, boil, and fermentation exceptionally precise, stable, and repeatable.
Brautomat32 is a versatile control platform for different heating and actuator concepts. Supported hardware includes GGM IDS induction cooktops, relay-controlled heating systems, and webhook-based actuators.
Operation happens directly in the browser and is designed for PC, tablet, and smartphone. An optional Nextion touch display can also be added.
Before every release, the firmware is tested automatically and in depth against real equipment. Build, flash, web interface, process flows, restore, and browser regressions are fixed parts of the release test workflows.
- Adaptive PID control with AutoTune
- Mash plan management with automatic temperature and timing flow
- Fermenter mode
- Actuator control and PWM outputs
- Temperature charting
- Backup and restore
- Firmware and web update
- Multilingual user interface
Brautomat32 is not designed as a simple temperature switch. The goal is a controller that runs processes cleanly, delivers repeatable results, and remains open to different hardware concepts.
Brautomat32 supports, among other things:
- up to three kettle channels
- Mash
- Boil/MLT
- HLT/Sparge
- DS18B20 sensors
- PT100x sensors via MAX31865
- Agitators, pumps, and additional actuators
- Fermenter operation with heating and cooling paths

Brautomat runs in current browsers on PC, tablet, and smartphone.
Brautomat32 supports almost any number of languages.
Brautomat offers three display views:
- Overview - shows all configured kettles
- Mash view - shows process data of kettle 1
- Manual control (GGM IDS2) - direct power control
Note: Display support is optional. Supported devices are Nextion ITEAD HMI 3.5" (Basic/Enhanced/Discovery series).
After updating from version 1.59 or older, AutoTune must be run once again.
