pylontech and daly smart bms different soc #1027

Describe the problem

Hello,

We have a pylontech 9.6kw battery and a DIY with 9.6kw and daly bms

Both batteries are summarized using the “Battery Aggregator” from @pulquero

Final charging voltage is 51.80V and trickle voltage is then 50.60V

This means that the pylontech has a soc of 93% and the Daly has 99.1%

is discharged up to 30% (ESS) so pylontech is around 24-25% and the daly is at 35-36%

So we have a difference of about 10% in the lower SOC range

In the serial driver we set the Soc calculation to true but we didn't notice any difference.

what can we do?

Reading the notes when opening a new issue would help :-)

Please also read the changelog.

Anyway, what are you hoping to achieve with the SOC calculation?
