We have designed KC868-A8 new board update for KC868-A4. Now add ethenret RJ45 port, relay up to 8 channel and place the IIC extend port on the PCB board. You can integrate to home assistant by ESPHome easily. use Ethenret cable will more stable than WiFi.
KC868-A8 smart controller , many hardware resource for you to use, you can write any code by Arduino IDE to ESP32 wifi/bluetooth/ethernet module. We will supply demo code for different samples. Everyone can modify and change the code for your own smart home automation system project.
