thanks for the tips and your patience with this noob ... i'm zeroing in on a solution, using the following:

1. itoa(rgbLed.redMappedValue,str,10);
or
2. String(rgbLed.redMappedValue).c_str();
client.publish("OsoyooDataF", str);

line 1 gives me 255 which is the range of the RGB LED from the setup;

analogWriteRange(255);

Line 2 gives me a blank field, still encouraging though because we are at least publishing something....

still tinkering with this, but logging out for now, can you offer me any more hint s?

if at all, version 2 should look like

client.publish("OsoyooDataF", String(rgbLed.redMappedValue).c_str());

step in the right direction, i'm getting an output, but it's the range value of 255 rather than the actual mapped value, almost there

as I don't now where in your sketch this line ended up, it can be everything.
Most likely the client.publish is happening at the wrong time/place where/when the wanted value is not (yet) / no longer stored in the published variable.
Do a serial.print at the same location and check if the variable holds the expected value.
