Start by removing the dashboard from the equation.

Make sure you can do what you want using the inject node first.

Thanks for the replay.I've solved programmatically using the browse function in the async array of the opc-ua library.

Any feedback about that?.  
I'm also looking how to send the endpoint and base node-id to node-red and then browse the next level, or browse the whole tree.

Do you know how to do that?.  
Thank you in advance.
