Smart battery loading

[ArneGollin1987]

Hi,
First off, great project! However I was hoping for a smart battery logic for surplus charging the battery during the day.
Something like:
Charge the battery ASAP to 30 or 40% via solar surplus.
Charge another 40% during peak solar, because my inverter can do 20 kw peak plus battery charging so it can reach 22kw peak production.
Charge the rest using solar forecast minus house consumption forecast so that the battery is full at the end of the day.

As it is now my 21kWh battery is full at 11:30 a.m. and is sitting at 100% for hours.

Since my export price is fixed, I don't care about charging during high/low spot market price, I just want my battery to live longer, and produce as much energy as possible.

Thanks in advance :-)
I could also help refining the logic and testing.

P.S. in the documentation it is written that I could swap the forecast integration from solacast to meteo, but I cannot find a setting to do so. It is fixed. The only way I can switch it is to deactivate solcast and forecast.solar , but I am using all three to make a comparison which one is most accurate for my location. So far meteo has several benefits, first highest time resolution forecast for tomorrow, so far best curve match of tomorrow's forecast to the actual production, and accurate total production forecast out of the box.

Cheers,
A.

Hi @ArneGollin1987, thanks — two good points here, and I logged both.

Smart surplus charging (charge to a buffer ASAP, top up during peak, then pace the rest off solar-minus-consumption forecast so you hit 100% at end of day): great idea, noted for the maintainer as enhancement #820. Your offer to help refine and test is very welcome.

Forecast source: you're right, and it's a real bug — filed as #819. SEM auto-detects in a fixed order (Solcast → Forecast.Solar → Open-Meteo) with no UI override, so with all three installed it always picks Solcast; deactivating the others is the only workaround today. The docs promised a manual setting that doesn't actually exist for the solar forecast (the "Forecast entity" field is the price forecast for dynamic tariffs). Both fixes are now in the maintainer's queue.

Thanks for the fast reply. And nicely summarized for the maintainer! 😀
