Same here. Even I am in specific time on higher % then scheduled „Targeted Soc“ system is against logic feeding the battery from grid.

It seems there is less PV than forecasted so DESS plans to use the grid to meet the target SOC. So this is not a bug. The forecasts will become more accurate once the system runs longer. At the moment your system only reported the data for a week.

@dirkjanfaber mhm might be but the main problem seems that the wheather is not like it is reported. It's cloudy and rainy but the system says sunny:

The weather widget on the dashboard comes from a weather API, not solcast and no interdependence with DESS. So there is no linkage between those two. But we are looking into why that widget was not matching reality on your system.
