It has 66 installs sharing analytics, works locally and was last updated October 23, 2026. ebusd Vaillant is a custom integration that connects Vaillant heating and hot water systems to Home Assistant through ebusd and MQTT. It runs locally and is set up in the UI with a device name and the MQTT topic prefix that ebusd publishes to. Entities are discovered as ebusd publishes its topics, so no manual entity configuration is needed. It provides climate controls for heating zones with HVAC mode, temperature control, holiday schedules and a quick veto boost, plus a water heater for hot water operation mode and temperatures. A water pressure sensor is included, and Boost and Away preset modes are available. Options cover default away and quick veto durations, the number of zones, startup discovery of devices, and whether only zones reporting a temperature get climate entities. It needs an eBUS adapter, an ebusd instance and the MQTT integration. Automatic summary of the README and code of signalkraft/ebusd-vaillant-component.

No vendor cloud in between. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### ebusd Vaillant - **Device name**: Name shown in entity labels, e.g. "Vaillant" produces "Vaillant Zone 1" - **MQTT topic prefix**: The root topic ebusd publishes to (default: ebusd) ### After setup - **Default away mode duration (days)**: Number of days the away mode lasts when activated (default: 7) - **Default quick veto duration (hours)**: Number of hours the quick veto lasts when triggered (default: 3) - **Number of zones**: Limits how many zone entities are created (default: 4) - **Discover devices on startup**: Tries to request typical MQTT topic names to be able to show values immediately on startup. If disabled, entities become available as MQTT values are published (default: on) - **Only zones with a temperature reading**: When enabled (default), only create climate entities for zones that report a current temperature. When disabled, create entities for all zones up to the configured maximum.
