• In order for IFTTT to access your ESP8266, you need to open a port to the outside world.
• Your WLED app will tell you what the internal IP address is for your ESP8266.
• Choose a none standard port for the outside (ie. 20015, 32265 etc) and port 80 on the internal port.
• Please refer to your routers instructions on setting up port forwarding.
• *It is not recommended to use the default port 80 open to the outside world*

*Note: IFTTT will prompt you to link your Google Account and give permissions for IFTTT*

• Sign up with IFTTT on IFTTT.com
• Click Create in the top right corner.
• Click "If This (Add)" with black background.
• Search for "Google Assistant" and click "Google Assistant"
• Click "Say a simple phrase" with black background.

• Under "What do you want to say?"
  • Enter the command you would say after "OK, Google..."
    Example: Enter "Turn on the moon" if your phrase was "OK, Google. Turn on the moon."
    
    
• Under "What's another way to say it? (optional)”
  • Enter a second command you would say after "OK, Google...”
    Example: Enter "moon on" if your phrase was "OK, Google. Moon on."
    
    
• Under "And another way? (optional)”

  [External IP Address]:[Port]/win&T=1&A=128&R=255&G=255&B=255
  • Just keep appending your GET string with &{parameter}={value}

Set [External IP Address] as your external ipv4 (ie 12.34.56.789)
Set [Port] number from Port Forwarding step after semicolon (ie :28956)
add /win after the port (ie :28956/win)
&T=1 || T means Toggle || 0(off), 1(on), 2(toggle on/off)
&A=128 || A means Brightness || value 0-255 (128 = 50% brightness)
