The `vallox` integration lets you control any Vallox ventilation unit that is supported by the [vallox_websocket_api](https://github.com/yozik04/vallox_websocket_api) (follow the link for a list of supported units).

The **fan** platform of this integration allows you to turn on/off the complete unit via the toggle switch, control fan speed and select a ventilation profile.

The **sensor** platform exposes a number of relevant metrics like fan speed, various air temperatures, and humidity.

The **switch** platform allows locking heat recovery bypass.

The **number** platform allows to control supply air temperatures.

## Profile Switching

For convenient switching of ventilation profiles in the GUI, just click on the `Vallox` fan entity to get a drop-down menu to select from. Alternatively, the service `fan/set_preset_mode` can be used.

The four standard Vallox profiles are supported:

- `At Home`
- `Away`
- `Boost`
- `Fireplace`
