BMV712 jumps from 80 to 100%

My BMV 712 shows e.g. 80%, this is realitic after using coffee machine and hair dryer in the morning. After sun raise, solar starts charing, early in the morning certainly just with a few watts.

If I close the app an reopen it a few minutes later, the BMV shows 100% although solar is charging.
This misbehaviour happened now a few times.

Jumping from 80 to 100% is quite bad, I need to know my remaining capacity more exactly....

Has anyone an idea, what wents wrong?

Thanks and best regards

Dirk

Have you followed any of the steps in the BMV manual that guides you about editing the necessary settings to make sure the sync is accurate?
