Changes in the configuration yaml still necessary?

[Gilly79]

At first, thank you for the great Integration !!!

1. I still had an old integration and this was still based on changes in yaml. If I see this correctly, I do not have to enter anything there to retrieve the data or?

2. Data I could retrieve and this described probably always the current month. To generate a consumption for a billing period I have to save the values myself and add up?

3. Is there any way to get the older data at ISTA? In the online portal I see data from last year?

PS. Is it allowed to write in German here or only in English?
