Good catch @guidoleijten ... Yep... a closer look at the function shows greater than num.dec and less than num.dec which leaves all exact num.dec to fall through as N

This explains the occasional glitch I have been seeing... one I had attributed to browser refresh or something interrupting the 10 minute update cycle I use.

A simple tweak changing the rest of the < symbols to <= corrected that.

As was in the initial beginning of the function

"New and Improved... Now with 99% more = "

let degreesToCardinal = function(deg){
  if (deg>11.25 && deg<=33.75){return "NNE";}
  else if (deg>33.75 && deg<=56.25){return "NE";}
  else if (deg>56.25 && deg<=78.75){return "ENE";}
  else if (deg>78.75 && deg<=101.25){return "E";}
  else if (deg>101.25 && deg<=123.75){return "ESE";}
  else if (deg>123.75 && deg<=146.25){return "SE";}
  else if (deg>146.25 && deg<=168.75){return "SSE";}
  else if (deg>168.75 && deg<=191.25){return "S";}
  else if (deg>191.25 && deg<=213.75){return "SSW";}
  else if (deg>213.75 && deg<=236.25){return "SW";}
  else if (deg>236.25 && deg<=258.75){return "WSW";}
  else if (deg>258.75 && deg<=281.25){return "W";}
  else if (deg>281.25 && deg<=303.75){return "WNW";}
  else if (deg>303.75 && deg<=326.25){return "NW";}
  else if (deg>326.25 && deg<=348.75){return "NNW";}
  else {return "N";}
}

With a bit Math may be simpler

function degToCompass(num) {
    var val = Math.floor((num / 22.5) + 0.5);
    var arr = ["N", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW"];
    return arr[(val % 16)];
}

Great minds think alike..

@Steve-Mcl

Or a simple function node containing...

const dir = ["N", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW", "N" ]
msg.payload = dir[Math.round((msg.payload % 360) / 22.5)];
return msg;

Yes, unfortunately Math and I do not compute So I tend to just grab what I can find and shoehorn it into my code

Eventually I tweak my stuff as I get a better understanding of the improvements offered. Thanks
