ESP8266 is not supported yet, only ESP32 boards

Can you provide a link to your board, I will buy one to make the library compatible

I bought my ESP8266 NodeMCU board on Wish.com. here's the link to my board: https://dl.wish.com/3iBSs
I'd really love if you made this excellent library compatible with ESP8266 boards

I thought it's supported because I saw it in the ESP32 Boards Supported part.

Can you provide a link to your board, I will buy one to make the library compatible

yes sure, you can find it in Aliexpress, this one Link
