i think you can connect the "Switch Terminal Board" to your raspberry pi USB-RS232 adapter. every time when you press the button, will have a command output to RS232, your home assistant can read the serial port message then make automation for which relay ON/OFF. just don't connect "Switch Terminal Board" with your KC868-H16B directly.
Unfortunately, my HA is running on a Windows VM. I'll see if i can map the host serial to the VM and try to read it. Thanks for the hint.
