do you have set some IFTTT? maybe you can factory reset the board. there is a "factry reset" button in KCS webpage. click it then test again.

no, I did not install it, I do not know what IFTTT is. I'm new to this, this is my first experience using HA and ESP Home. So if you can tell me in more detail what I should do. thanks

you can download KCS v3 firmware to test a long time , whether work well. here is KCS v3 online guide: https://www.kincony.com/how-to-use-kcsv3-firmware-esp32-board.html

OK, I'll try.

The framework uses type: arduino

Currently I have a board set up and in use over wifi. It uses type: esp_idf. 
I want to change to ethernet. Do I have to change the type to arduino? 

Thanks!

RE: KC868-A16 ethernet work with home assistant by ESPHome configure - admin - 02-22-2026

ardunio or esp_idf all support use by ethernet. you can use any platform.

That's awesome, thanks!

So, just to confirm. If delete the wifi section and add this to my current working .yaml then the ethernet should be working without any problems, right?

Code:
# Example configuration entry
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk:
    pin: GPIO17
    mode: CLK_OUT
  phy_addr: 0


RE: KC868-A16 ethernet work with home assistant by ESPHome configure - admin - 02-23-2026

yes, it's right.

So, I'm about to replace the wifi section of the KC868-A16 to this:
Code:
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0
But chatgpt is arguing that it isn't the correct configuration for the board. It says I should use this config:
Code:
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO0_IN
  phy_addr: 1
  power_pin: GPIO5


RE: KC868-A16 ethernet work with home assistant by ESPHome configure - admin - 03-18-2026

A16 ethernet config yaml should be:
Code:
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk:
    pin: GPIO17
    mode: CLK_OUT
  phy_addr: 0
