Hello,
I have bought an 32 Input board. I would link the input to my Homeassistant as a Door Contact maybe.
But the manuall is all in China.
Can anyone help me? Maybe a member who had also the same board.
I had the Modul in my network with an local IP adress.
Example: Read 32-way DI, module address = 1:
Modbus TCP format: Hexadecimal
Host sends: 00 00 00 00 00 00 06 01 02 00 00 00 20
Slave Answer: 00 00 00 00 00 00 07 01 02 04 03 FF 01 02
Message Details:

03 indicates: DI-0, DI-1 high level ON, other low level OFF
The FF from low to high represents the input state of the DI8-DI15
FF means: DI-8–DI-15 All High Level ON
01 From low to high represents the input state of the DI16-DI123
