What happened?

Since a while I have the feeling that on a nearly flat price day the system not calculate for the customer and today is such a day.

When did it happen?

It looks like this is caused by the "blaming the wrong consumption on the grid" that the system uses right now. There was less solar than expected and the system charged the difference from the grid. Once again, we are aware of this and will come with a good solution. Until then, there is not much to do about it.

Can you try again with running version 0.0.14 with firmware 3.30~7 (or above when released)? This adds extra strategies for not blaming the wrong forecasts on the grid all of the time.

Closing this issue. Please re-open a new issue if the problem persists.
