From the README

Home Assistant integration for ETA heating systems (pellet, wood, and combined boilers). It reads sensors, states and counters from your ETA unit, and lets you switch and set writable parameters — all discovered automatically over the local ETA REST API, no cloud required.
Automatic discovery of every available endpoint on your ETA unit — with live values shown during setup so you can pick the ones you want.
Sensors for all numeric values (temperatures, pressures, power, flow, counters, …).
State sensors for text states (e.g. Ready, Heating).
Switches for on/off parameters, detected language-independently.
Writable parameters as number entities for setpoints (°C, kg, %, …).
Schedules as time entities (API v1.2+).
Error monitoring: a binary sensor for active errors, the active-error count, the latest error message, plus error events for automations.
Services to write values directly to the unit (details).
Stable entity identities: entity ids stay stable across firmware updates, terminal language changes and IP changes.
Energy Dashboard ready (details).
