Forecast pricing interval used

[harmendp]

HEllo,

I'm making good progress in setting up HAEO for my usecase. I do have a question though.
I'm using the Entsoe integration for energy prices. I had to create a help to transform the attributes to the correct format and that seems to work well now.

However, forecasting seems to use, for any interval, the price at the end of the interval in stead of the current one at the beginning of the interval. You can see this when there is a price peak. The forecast oscillates utill the peak reaches the 'current' value.

Entsoe has 15min intervals. Let's say there is a peak in 30min from now. Then the power forecast will show a peak in 45mins.
Once this peak approaches, the forecast shifts towards now, but always one interval to far. So it seems the optimization engine, uses the price point at the end of the interval and not the one at the beginning. Not sure if I'm clear :-)

Is this the intended behaviour, or a setting I can change somewhere?

Thanks!
