About This Project

A project for predicting pellet consumption in a furnace to optimize its settings and minimize operating costs.

Hardware

  • ESP32 (PlatformIO/Arduino)
  • 3× DS18B20 temperature sensors (OneWire/Dallas)
  • Distance sensor (tank level measurement)

Features

  • Readings every ~6 s, median over a 60-second window → pushed to Firebase every minute
  • ESP32 web server (ESPAsyncWebServer) — local data preview
  • WhatsApp alerts via HTTP API
  • Automatic WiFi reconnect
  • Dedicated FreeRTOS task for Firebase

Frontend

Static HTML + JS + CSS page (data/) querying Firebase or the local web server. Data visualization implemented in Python.
