Growatt Mod Inverter - SDM630 Smartmeter values over RS485

Hello togehter,

I habe 2 Growatt Mod inverters. One Inverter is connectet to a SDM630 smartmeter for battery charging. It works well.

I want now to get the real time values from the smartmeter in my HA, for correct power counting (growatt shine app can´t do this), but I didn´t find the correct entity.

Does someone have an idea which value i need?

I use:
sensor.growatt_haus_grid_export_power
→ See export power, but at the moment i only import.

sensor.growatt_haus_grid_import_power
→ See zero import, but its not true.

I hope I can read out the smartmeter values with the mod inverters and save the money for an additional shelly after the grid meter.

Edit:
I use HACS with growatt modbus addon.

Thank you very much.
