Default calibration for ampmeter coming with OpenEVSE box is $SA 220 0. Which is perfect for normal / high charge current.
But when using solat diver, lower charge current are completely of by 0.25A and I need to set $SA 190 0 to calibrate.
Here is a comparison with a Shelly EM which was confirmed being accurate:
is there a way to set a sort of factor so that 190 is used for lower current and then 220 ?
Right now, in Home Assistant I am using an automation that is setting the right calibration value depending if I am using AUTO mode with solar divert (which means low charge currents) or Manual mode (which mean high charge current)
