@pinguino excuse me, my name is Raúl y I write from Spain. I´m searching how to read AC consumition and other informatións like you.
I have a Solplanet AIS 6000H - S2 and I only have a meter port (to read meter SDM230), a Wifi Stick port (to transmit information to the aiswei Cloud) and a CAM BUS port...(Battery)
¿Have you get this information?

¿Have you read this to try get/put data from/to inverter using the API https://www.vegt.dev/blog/link-your-solar-inverter-to-home-assistant-using-modbus-serial?
Thank you very much.
