The adapter is this one: https://adapter.ebusd.eu/v5/ See also https://adapter.ebusd.eu/v5/steps.html

It's all self-installed. The #openhab host also runs #ebusd (https://github.com/john30/ebusd), and the values are sent to openhab as #mqtt messages.

There's a large amount of data. We got the adapter in July (I can see from my above message) and immediately started importing and charting the first values. Then came vacation time and now the start of the school year. But I think when it gets colder, there will be more interest in the other values.  

There's still a lot to explore. We got the #heatpump in the spring and except for some tests it has only been used for heating water so far. I have the temperature of the various liquids: inside and outside circuits, incoming, outgoing, the water temperature, and of course the outside air temperature. Then there's lots of status values and status texts, error codes of course, and there should be energy values as well (all the things you can see on the built-in display of the heatpump). There's statistics like runtime in minutes for the various functions (heating, cooling, de-icing, ...).

We also have the inside and the outside elements of the heat pump hooked up to shellys in the electric cabinet so we can see how much electricity they use directly and in more detail.
