How It Could Work
Wire a 1–2 kg load cell through an HX711 to an ESP32-S3 (T-Display-S3 makes a nice UI). Firmware zeros the scale, detects the dose, starts a timer when weight rises again (pour), and publishes weight + brew time over MQTT/ESPHome. Optional BLE advertising for a phone widget. 3D-printed platform under portafilter or dripper.
