I'd like to set up a slider or three sliders RGB.. and have an MQTT MSG sent in the form
LED=R,G,B to topic NODE-ESP......
I'm struggling... even to get a msg sent to a topic of my choosing.
Anyone have any experience with MQTT and this.....

I've figured out how to get a colour picker working very nicely.
What I've not figured out is how to send out an MQTT msg.
How do I configure a MQTT_DEVICE to send out the state of a dummy variable as a message with a particular topic?
