Pellet Pulse is an ESP32-based data bridge for Ökofen pellet heating systems. It retrieves live data from the heater's internal HTTP interface and publishes it for use in smart home automation, energy tracking, and more. The system is designed to be standalone, Wi-Fi enabled, and easily configurable via a built-in web interface.
- 🔌 Connects to Ökofen pellet heating systems via HTTP
- 📊 Parses heating metrics like temperature, power, energy, and storage levels
- ☁️ Sends data to a configurable HTTP endpoint (e.g. HeatGeniusAI, Supabase, Airtable, Node-RED etc.)
- 🌐 Web interface for:
- Configuring IP, port, password, and polling interval (Your Ökofen heater)
- Configuring, endpoint, API key and format
- Viewing live status
- 📶 ESP32 firmware with OTA update support
- 💾 Persistent configuration via LittleFS
