DESS being too optimistic about PV generation hours

@dfaber

Hello,

In recent days, I’ve noticed that DESS is overly optimistic about PV generation hours. As shown in the screenshots, actual production starts around 07:00, but DESS forecasts it from 05:00. Would it be possible to add a configuration option to adjust the PV production timeframe?

Is your location in VRM correct?

Yes, location is correct.

Did you notice that the forecast functions were only available to a limited extent for a few days? And that’s with decreasing day lengths? I imagine it might take a few days to settle down again.

Hope so, but do not believe. I’m turning off DESS now until real sunshine.
