1 year ago Hi, it is not implemented yet but basically possible if you want it. The first test is to use the testscript and adapt the request string according your X1 mini modbus protokoll. https://github.com/tobiasfaust/SolaxModbusGateway/tree/master/examples/test_RS485_SolaxMini_ESP32
Modbus protokol is here: https://raw.githubusercontent.com/syssi/esphome-modbus-solax-x1/main/docs/SolaxPower%20Single%20Phase%20External%20Communication%20Protocol%20-%20X1%20Series%20V1.8.pdf
A good start could be to request the device info with String: 0xAA 0x55 0x01 0x00 0x00 SolaxMiniAddress 0x11 0x03 0x00
Header, Source, Destination, ControlCode, FunctionCode, DataLangth, Checksum (will add automatically in test sketch)
After it works successfully (you get an valid answer to your request) its easy to add it.
Alternative solutions for you are there:

Does anyone has implemented the SolaX Mini inverters? I have an old one (without display, only LEDs) and a newer one with the status display. And... What has to be configured in the menu to communicate with the ESP? Does the SolaXModbusGateway simulates a meter? This is the only thing I could enter in the menu. I would like to implement these inverters in my Venus OS (Victron Energy) as AC inverters.
