The Brautomat is a brewing controller for the ESP8266 and ESP32 D1 mini. The Brautomat offers an intuitive, easy-to-use control system.
Note: With version 1.50 all Brautomat versions (Brautomat (ESP8266), Brautomat32 (ESP32 IDF4) and Brautomat32pIO (ESP32 IDF5)) are published in the Brautomat32 repository.
The Brautomat can be operated on an ESP32 or an ESP8266. The ESP32 with the Brautomat32pIO firmware is recommended.
For compatibility reasons, a Brautomat32 version based on ESP32-IDF4 also exists for the ESP32.

The Brautomat is operated via web browser. You can use your tablet, smartphone or pc.
Brautomat offers three different displays:
- Overview
- Mash tun
- Manual control cooking
Note: the display is an optional extension. Only Nextion ITEAD HMI 3.5" Touchdisplays are supported.
Brautomat32 supports (almost) any number of languages. Each language has its own language file. The language files in JSON format are stored in the folder data/language.
Support this project and translate Brautomat into a new language or correct existing language files!
A board for the Arduino ESP controller is available. In addition to the screw terminal blocks for the GPIOs, the board also offers a separate connection for the induction hob and three connections for temperature sensors. The Gerber file is stored in the Gehaeuse folder. The board 2.1 can be operated with both the ESP8266 and the ESP32.
The ESP32 D1 offers a pinout suitable for the ESP8266 (GPIO D0 to D8). The pin assignment shown is based on the ESP32 D1 Mini NodeMCU module from AZ-Delivery
