Home Assistant integration for Vaillant heat pumps via direct ebusd TCP — no MQTT, no cloud.
- Drop-in replacement for mypyllant API integration — same entities, no cloud
- Direct TCP connection to ebusd — zero MQTT setup required
- Dynamically discovers available circuits and registers on connect
- Generates native Home Assistant entities for sensors, controls, climate, water heating, calendars, and dates
- Climate entities with quick veto and away mode (calendar-based scheduling) — one thermostat and flow-temperature-range per discovered heating zone on multi-zone systems
- Cooling control — read and write the manual cooling period ("cool until [date]") via the climate COOL mode and dedicated datetime entities
- Water heater entities with DHW boost and temperature control
- Read & write any register via HA services (vaillant_ebus.read_parameter, vaillant_ebus.write_parameter)
- Custom registers via --enabledefine (e.g. room humidity, manual cooling dates)
- YAML overrides for entity metadata (names, icons, units)
