I have installed the ui\_LED on one machine and it works. I send it either a `true` and the LED goes GREEN.

Sending a `~true` and it turns RED.

This is on NR 0.19.4

I installed the node on another machine running NR 0.19.5.

I can't see the LED on the dashboard.

I'll try other things, but I'm stuck on what to do.

2.9.8

I've been trying for 20+ minutes to update it.  
From the web page it just doesn't work.

Trying from the CLI. Same.

From the CLI in the .node-red directory:  
`npm install node-red-dashboard`

NO LUCK! ☹

This is what I see:

```auto
pi@TimePi:~/.node-red $ npm install node-red-dashboard

  run `npm audit fix` to fix them, or `npm audit` for details

```

Back to "that old problem", I fear.

This is also a bit of other info which may be helpful.

Well, for the last hour I can not update the dashboard from 2.9.8 to the latest.  
The other machines have 2.13.x

The gui doesn't appear on the dashboard.

So I am trying to update from the CLI.

Still not working.

It completes, gives the reply as shown.

```auto
pi@TimePi:~/.node-red $ npm install node-red-dashboard
npm WARN node-red-project@0.0.1 No repository field.
npm WARN node-red-project@0.0.1 No license field.

found 6 low severity vulnerabilities
  run `npm audit fix` to fix them, or `npm audit` for details

```

I reboot (not really happy doing it, but....)

Same version of the dashboard. 2.9.8

So, what do I do now to get it updated?

I am trying, but it is just confusing me.

The program gives me messages saying things are not up to date.  
I am told to not worry about them.

So.....

Stuck.  
😖

Some how it has now updated.

The dashboard is now up to date and the LED is now showing.

Spoke too soon.

The LED appears, but sending `true` or `false` the LED doesn't change colour.

Which version of the Node-RED dashboard have you installed, and do you see any errors in the console log of your browser (where the dashboard is running)?

</div>

The Node-RED is running on my computer. I installed it through CMD based on this link:  
[https://nodered.org/docs/getting-started/windows?fbclid=IwAR13v5z748blFi2tM4cJ7VxlG5ugjOcl4MDXY0tPBL7IuK3l2lj77eIxb0E](https://nodered.org/docs/getting-started/windows?fbclid=IwAR13v5z748blFi2tM4cJ7VxlG5ugjOcl4MDXY0tPBL7IuK3l2lj77eIxb0E)

The dashboard is running on my web browser (google). Dashboard Version 2.22.1.

I see the error here:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/f/0/f065d182170d9ea188a1fbb23fbc7e6212ced7dd.png)

I have 5 days (~10hours) of Node-RED experience, so perhaps I am missing some basic thing.

Hi Pesel,  
could it be that you have mixed up two questions? Think your screenshot is about the mp3 [discussion](https://discourse.nodered.org/t/playing-mp3-audio/8188/18), not about ui\_led? Or am I mistaken?

No. In the same project I have 2 issue (: I connected a Siemens 1200 PLC to the system and I connected a LED and a switch to that. I can see in the node-RED if I switch on the PLC and I can also switch the LED in the node-RED. But I have no visualization on the dashboard for the LED. I found this ui\_LED node, which is exactly for this purpose, but it doesn't want to work. I can not see it on the dashboard.

Can you export the nodes you have shown grouped (assuming they are the ones that are not working for you) and paste them here. See [this post](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506) for how to do that.

Also open the Developer Console in the browser (how to do that depends on the browser, probably in Tools \> Developer or something similar), refresh the page and see if any errors are shown.

Possibly a browser caching issue.

Hi All.

Sorry to revive this archived item. My UI-LED isn't working at all... not even showing up grey in the dash.

Here is a copy of the node-red-log after restart:

I have done numerous things to try to resolve it; up to and including restarting with a fresh rpi install (changed order of palette module installs, rebooting between every additional palette module install.

Here is a copy of the log after trying to change properties and deploying them:

```

I don't know what else to do!

Node-red installed from the script just today.

Note: I did update a different rpi4 last Friday due to a failed SSD; had no issues whatsoever bringing that system back online. I uploaded a .json file to my browser after burning new system onto new ssd. I try the same thing today to create a new system for a new customer and the LEDs for the dash aren't working.

Any help will be appreciated.

Show us the log from the node-red start.

Hi Colin.

Thanks for the reply.

Here is the log directly after booting up:

```

It's basically the same as after a restart, I hope it can help diagnose the issue.

Stop node red and start it again in a terminal  
`node-red-stop`  
`node-red-start`  
And post the full output.

Here it is... it's long. It looks like an error or set of errors for every instance of the UI-LED I have.

```auto
Start Node-RED

Once Node-RED has started, point a browser at http://192.168.0.37:1880
On Pi Node-RED works better with the Firefox or Chrome browser

Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

To find more nodes and example flows - go to http://flows.nodered.org

Starting as a systemd service.
