Instructions
Find the following nodes in the Node-RED palette:
Link in & Link out
dashboard button → User application
function
Vertex action
Vertex cluster
Template
2. Each button in the app is assigned to a specific function setting a given color. In function nodes (Red, Green, Blue, etc.) the variable color is created and we assign the color.payload with the appropriate color configuration. For Red button it should look like this:
3. RGB conversion function outputs properly rescaled RGB values corresponding with the placement of your mouse cursor on the circle color picker.
Copy and paste the code below:
var color = {};
var red = Math.abs((msg.payload.r-1));
var green = Math.abs((msg.payload.g-1));
var blue = Math.abs((msg.payload.b-1));
color.payload = {"ch0":red,"ch1":green,"ch2":blue};
return color;4. Configure vertex action nodes as shown below:
First vertex action node is responsible for setting the RGB led brightness. Enter a value that suits you best.
The second action node translates the RGB value for the appropriate Vertex controller command.
5. Import the Template node attached below. It will prevent from accidental zooming or exiting the app.

6. Link all nodes together. Then select Deploy and test your flow.
