Need help connecting FoxESS H3 12.0E

Hi all,
I struggle connecting my Fox H3 inverter to HA.
So far I connected a Waveshare RS485 to ETH Modbus adapter an did the setting as shown here: config RS485
I can access the Web-GUI from the Waveshare via LAN. Also I checked the Device-ID from the H3.
I’m not sure how to connect the H3 with the Waveshare because I didn’t find any information about this. So I connected Pin 1 to RS485A and Pin 2 to RS485B.

But the connection in the FoxESS-Modbus integration shows an error…

Maybe someone can help me to get this running.
thanks so far

Got it working now. But energy dashboard shown only 0 values.
OK, needs a while everything is fine now.
