| timeZone | The time zone the hour definitions of the things below refer to. Default is `CET`, as it corresponds to the aWATTar API. It is strongly recommended not to change this. However, if you do so, be aware that the prices delivered by the API will not cover a whole calendar day in this timezone. **Advanced** |
| country | The country prices should be received for. Use `DE` for Germany or `AT` for Austria. `DE` is the default. |
Note: The prices include already the 3% and 1.5 €cent per kWh fees for the aWATTar service.

The prices thing does not need any configuration.
