KC868-HA RS485 Button Adapter Released

[tatu]

1. I want six entities to Home Assistant (with ESPHome) wich can turn on/off KC868-HA D1-D6-outputs    --->This i think can do.
2. And six entities that will show input K1-K6 state    --->  in home asisstant can't show K1-K6 state for "ON/OFF",  only can get a message from key is pressed, i don't know do you understand me?

2. Messages will be fine, I can convert them to actions what I need. Can you assist how to add this to ESPHome?
