Hi,  
have placed this LED but it's not displaying on dashboard, not red, green or grey.  
The boolean status changes in debug windows seems ok.

But the layout editor shows the group and the led inside:

I could not reproduce the issue. Running same version of Node-Red, dashboard an contrib-node.

What is the browser your are using to run the dashboard ? Did you try on another browser ? See any error in devtool console ?

Have test it under Windows 10 with Firefox, Chrome and Edge. LED is not displayed.  
In devtool console no errors, only warnings.

Here is my flow:

Imported the flow but replaced the s7 contrib node by an inject node.

It works.

LED is now displayed.

Solution: Update to json-c-0.11-4.el7\_0.x86\_64 solved the problem.

Thanks for your support.

I have the same issue. I'm using the official nodered docker image.  
Could it be, that json is not up to date in the image?

Thanks in advance

Hey @tiby007,  
Please don't ask the same question in multiple discussions! Because that makes it very hard for people to keep track of all questions...
