Daly BMS - Current values are not displayed in the app or in the PC software

[smitie]

Hi everyone,
I bought a Daly BMS 4S, 12V, 200A, common port, BT and UART Interface through aliexpress. Unfortunately, neither the app nor the PC (Sinowealth) shows the current and therefore no power. Everything else works fine in my opinion. After 4 weeks of support from the manufacturer I got the answer "... I think the bms is working and can't tell there is a problem"!
Does anyone of you have any idea why this could be?

I've got the 300a and have been having a play with it the last couple of weeks.
In the sinowealth under the calibrate tab down the bottom, what values do you have for working current and zero current?

Thanks for your answer, but I sold the bms on ebay today.

I have the 4S 12V 100A and had the same problem.

Solved the problem by doing calibrate 'zero amps' first and then calibrate with a known amperage like 5 amps.
Use positive values for charging and negative for discharge.

When the bms hits OverVoltage or UnderVoltage, I had to repeat the calibration.

When the bms hits OverVoltage or UnderVoltage, I had to repeat the calibration.

Tried to repeat this OV and UV condition, but now the current display stays OK.

Current needs to be over 2.5 amps for it to display with my bms.

Thanks, I hadn't hooked mine up to a PC yet, but correctly calibrating will give me incentive to do so.
