adding KC868-HA RS485 zo HA or ESPHome

[dragos]

i suggest you let 1 gang switch work with F8 using HAv2 directly, just without home assistant, because it will stable, even if home assistant broken, your switch panel also can work. because the esp32 work locally.
so download KCS v3 firmware to F8, then enable RS485 work by "MODBUS-HA" option, will be easiest way.

HomeAssistant in that house handles a lot more, not only this ESPHOME from F8. I need HA in the picture, it's very important.

Also ESPHOME on F8 is necessary because it also collects other sensors on RS485, not only the HAv2 (although right now, it only has HAv2 into rs485).

I agree that esp32 locally is a better option, but not in this project.

I've attached the yaml file we have on esphome.
