Smart bmv only showing voltage, current and power is 0

e4b48e95-d380-4360-92f1-888351c3c537.pngI am having difficulties getting the current and power to show, I am in able to get my batteries charged. Or show that they are. To my understanding I have everything wired correctly. Here is the diagram I sent off of and here it is wired up.

If it is wired ad shown in the diagram it should work.

Please check the wiring again, if everything is correct contact the seller from whom you bought the SmartShunt.

Yes everything is wired just like that, I’ve checked it at least 3 times.

Is it set for the 500A/50mV shunt?

Are you using the aux input? If so, for what?

If everything appears to be in order, I would disconnect the load side of the shunt and conduct a zero current calibration.

What is the aux for? On the shunt? And how do you perform a zero current calibration test
