SMA Sensor - does the sensor work with a Battery Inventor Sunny Island?

Configuration
1

I have an STP9000 and a Sunny Island 6000 with Batteries to store the Power. I can’t get the SMA Sensor to read the values from the battery inventor. Connection to speedwire seems to work but can’t get to reading the key values.

Did you ever get it yo work?
I have tried a few ways including modbus but no luck.

No, never. I gave up…
