brewce: Brewing Beer with Zephyr, Android and Thingsboard
summary
A homebrew automation rig is built and shown working: a reverse engineered induction cooker plus a remote thermocouple probe and a pump controller, all controlled over Zephyr RTOS and BLE from an Android app. Firmware and PCB details are published, MQTT telemetry feeds a ThingsBoard dashboard, PID values are usable but not tuned, several prototypes destroyed during hacking, and the final setup runs mashing profiles end-to-end.
