Hello everyone,
Last week I finished my solar system with a DIY LiFePo4 battery and Daly BMS. I tried to connect BMS by RS485 protocol with USB to RS485 converter through the serial port. First I installed the driver of the serial interface to Cerbo GX with SSH as root. The driver is working correctly, but the received data from BMS is the opposite of the real measured current. That means the Smart Shunt showed a charging process while BMS on RS485 showed discharging. This is the same in discharging process as well. The smart BMS app and the touch screen show the correct current flowing. There is some kind of logical issue, but I don't know how to repair it. Could somebody tell me what is going on with BMS?
