Perhaps you have it on the wrong dashboard tab?

There is no LED in the nodes installed with node-red-dashboard so can you please confirm  
What dashboard have you installed?  
What LED contrib node are you using?

A screencapture of the dashboard showing the nodes which do work would be useful, also an export of the LED node and the nodes which connect to it.

Confirm what message you are sending into the LED node.

Is there a reason why you are using dashboard-evi rather than the "official" dashboard nodes node-red-dashboard?

The github pages for dashboard-evi seem to have disappeared, not a good sign.

I am not an expert:

That doesn't look _right_.

Why are you _complicating_ things?

Out of nothing but curiosity:

What are the other payloads you send into the other (working) LED nodes?

(You should post the actual code and not cropped screen shots - it makes it easier for all)

So you are saying you have a `function` node with:

```auto
var msg0 = {payload:msg.payload[0]};
return [msg0];

```

So `msg.payload[0]` is the important part - yes?

Again: I am not an expert, but that looks structurally bad. (wrong)  
But that's only what I think and if you say it works elsewhere.... Who am I to say otherwise?

Have you CONFIRMED (via a `debug` node) what is being SENT?  
(NOT what you THINK is being sent)

That doesn't show me the output of the `debug` node so doesn't _prove_ anything.

And - thinking about it - are you SURE the LED node is configured correctly also?

(Oh, the `debug` node will have to show COMPLETE MESSAGE BODY also. Not the default!)

</div>

How can I when I don't know how you have the `LED node` configured?

Basically you need to show _us_ the payloads (sorry: Complete message) being sent INTO the `LED` node and how that node is configured.
