Describe the problem you have/What new integration you would like

Please describe your use case for this integration and alternatives you've tried:

Additional context

Hi all, I see EspHome have this 2 new super usefull integration: Daly BMS and PipSolar PV Inverter. As many new PipSolar and other brands have a Rs485/can port to communicate directly to Bms, to get accurate SOC % and Volt data to properly manage Litio battery charging. I wonder if is possible to implement this function.using the Lib protocol or others. It would be the "Cherry on the cake. Actually Inverter use his battery voltage to Stop charging/discharging the battery...and this is no accurate.

Thank you

I believe the difference in battery voltage is OK: image Also, I think the daly bms SOC is almost just as bad as the inverter SOC. Daly shows 100% when my battery is probably closer to 80%. But nevertheless it would be nice to have this feature.
