This project contains the schematics, code and 3D models for a coffee scale based on an ESP32.
- OTA updates via WiFi
- Recipe-based brewing
- Auto averaging of weight values: more values are used to determine weight when weight is relatively constant
- Brew timer
- USB-C charging
- Interchangeable Load Cell
- 3D-printable case
- Bluetooth and Wi-Fi connectivity
The scale can be used to brew coffee using a step-by-step recipe. The recipe is stored on the scale, and can be adjusted while brewing.
Possible adjustments include:
- Changing the amount of coffee
- Changing the brew ratio
- Other adjustments based on the chosen recipe
