I think, you have to modify different issues in the code:
How to programming with KC868-A8 - Smart Home Automation | KinCony
See sample codes for using ethernet, reading inputs and writing outputs.
I guess, Matthias is using W5500 Ethernet Chip. All IO’s are directly wired to the esp, in your case via i2C …
For my ratecontroller I planning to use a A8 board, which I have ordered recently!
In the Kincony A16 forum, you can find all example codes:

edit:
a little confusion which liberary is used, it’s definitely part of arduino_esp32:

Did the board arrive, did you manage to configure it?
It takes another two weeks to get the board shipped by ali. I prepared some code for testing it as platform board for SK21’s rate controller.
You can help to configure the section control file for this board so that it can be connected to the computer with a Lan cable, control 8 output relays, for section control. No programming knowledge myself.
I will have a look into this code too …
