THEMA:

Installing correctly, confirming in Applications.
Kapazatat used as wha input and Motorspan as V input, I think it's correct.
No reaction in OneCapacity window on DS16
Reset and test again and the app give ERROR as status - see screenshots.
(reset is not a momentary switch, it's a 2 ways one) What happen if reset switch is to "reset" when you start motor(for example) ?
Not lucky me or ?

Value used Motorspan in Volt
Kapazitat in A
from an old log to show that both value are exact ! ( 5S in this case)

Please post setup-screen from OneCapacity?

here it is. True sensor is in Ah on the screen mhA..............

Same with 4.27 and 4.28 - DS16 -

There was a stupid error by my side, could you please try this and let me know.

The settings are zero after reboot since app have crashed.
