Huawei inverters use a dongle as bridge to accept modbus tcp requests and map them to modbus rtu. With this more than one inverter can be connected to the dongle.
When wanting to read registers from one or the other inverter, the unit ID is needed to identify the correct inverter.
Please add support for that, many thanks in advance.

Device Address is 2.
If I look at the packets in wireshark I see:
Unit Identifier 1
Unit Identifier does not change if I change the device_address in the config.
Any tips?
Error is:
ValueError: Failed to read 1 holding table registers starting from 32107: Modbus Error: [Input/Output] No Response received from the remote unit/Unable to decode response
