Not that Miele finally put their 3rd party API into public Beta, it could be worth creating a component for it.
In general, all devices that are added to the [email protected] app, can be used with the API.
The API is documented here: http://developer.miele.com
Are there any more people interested in creating a component for the miele API? I’ve started playing around a bit but currently struggle as the connection from my Miele devices to the Miele cloud is fairly instable (still investigating in that).
