Brautomat

ESP32

Brautomat is a brewing controller for ESP32 D1 mini systems. It automates mash rests and timing, supports boil phases including hop additions, and can run infusion-style mash processes with minimal manual intervention.

Note: This guide is continuously improved. Many examples use GGM IDS. Since version 1.48, relay-based setups are supported as well. Only manual mode is exclusive to GGM IDS2.

Guide status: release line main (version 1.60). Local development builds may differ.
