Error reading Register from Sungrow Wallbox #28

Hello,

I am trying to read data from the Sungrow wallbox via Modbus.

The query:

modbus 192.168.179.9:502 -s 2 21203
Parsed 0 registers definitions from 1 files
21203: 1 0x1

also provides a correct result.

If I use the -r option, however, I always get an error message: "struct.error" or "AssertionError".
I have already tested all options.
The return value is "0" or "1".

Thank you and best regards
Hubertus
