I did some experiment with LOLIN D1 mini pro ESP8266, RGB led matrix and RGBW led
artnet thru wifi
I'm happy to share :

// Please include ArtnetWiFi.h to use Artnet on the platform
// which can use both WiFi and Ethernet
#include <ArtnetWiFi.h>
// this is also valid for other platforms which can use only WiFi
// #include <Artnet.h>
