Read data from SmartMeter

I’m curious, is there anyone who come to the same idea as me.
I have FV and obviously there is Smartmeter between grid and an inverter.
I can access the meter data connecting to the inverter. But once inverter is disabled (for whatever reasons) I lost measurement.

The idea is to use data published by the Smartmeter in HA without the inverter in the middle.
In my case, SmartMeter sends data to Inverter using Modbus over RS485. Do you think it’s possible to get those data directly to HA too?

If you find some info about registers it would be easier…
