Energy Dashboard self-consumed solar power calculation

Hello,

I’ve set up successsfully HA and the Energy Dashboard. The single values itself look reasonable, but the calculated amount of self-consumed solarpower seems not to be reasonable. If you have a look at the screenshot there is quite a lot of solar power assigned to the power grid (purple bar) instead of the house (orange bar within the blue one). It’s a cloudy weather and the heat pump is continously consuming approx. 1kW and therefore I would expect that almost 100% of the solar power is consumed. Could it be a calculation issue due to the fact that the values from the different energy meters are send asynchronously to HA. Has anyone an idea how I can find the root cause that I can try to find a work around?

Thank you,
Armin
