KC868-M16v2 configure yaml for ESPhome

[sanketgroup]

whether use STATIC or DHCP according to esphome yaml file.
if you don't know what is esphome, check here: https://esphome.io/index.html

attached is the screenshot. 
From HA's ESPHome, I clicked Prepare for first use.

It does install but then since there is no wifi antenna, it cannot connect to wifi network.

I plugged CAT6 but then I am not sure what to do next?

Do I have to put those 3 files on Home Assistant before clicking " Prepare for first use" ?
