Hei,
Have any of you done this project?
I’m having some issues compiling this sketch for the Wemos D1 Mini.
Not even the example card is working:
“Error compiling for board NodeMCU 1.0 (ESP-12E Module).”
“Error compiling for board LOLIN(WEMOS) D1 R2 & mini.”
Seems to compile just fine for me:
(however, I’m using PlatformIO and not the Arduino IDE)
What are the specific errors that you’re getting?
Arduino: 1.8.9 (Windows 7), Board: “LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Disabled, All SSL ciphers (most compatible), 4M (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 921600”
Build options changed, rebuilding all

This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.
I think this is the problem: you have two versions of ESP8266WiFi installed, and they might be conflicting. Remove the first one (in C:\Users\ajn\Documents\Arduino\libraries\) and try again.
