Great so now you can communicate between NR and espeasy! Now you need to learn about how ESPeasy works. I'd suggest you go read [https://www.letscontrolit.com/wiki/index.php/Tutorial\_Rules](https://www.letscontrolit.com/wiki/index.php/Tutorial_Rules)

BTW there are a couple neopixel commands and in all cases `r` is the red value, `g` is the green value and `b` is the blue value:

`NeoPixel,n,r,g,b` where `n` is the NeoPixel number,  
`NeoPixelAll,r,g,b`  
`NeoPixelLine,s,e,r,g,b` where `s` if the starting LED and `e` is the ending LED

One note on NeoPixelAll: if you have a 12 neopixel strip or circle you can not say NeoPixelAll,10,3,25,0,0 - the end has to be great than the start so in thin case you would need two commands `NeoPixelAll,1,3,25,0,0` and `NeoPixelAll,10,12,25,0,0'
