I want to add the node-red-contrib-opcua to the palette. I actually installed it with npm, but I can't find it in node red.

Then I tried to install it directly through the mange palette, that didn't work either.

To install with NPM, you need to

- install to the userDir folder
  - usually `.node-red` but check the logs to be certain (look for the node-red entry that states `userDir`)

- restart node-red
- refresh browser

Additionally, you have installed as `root` - why?  
what user runs node-red?

Lastly, I see this is an iot2000 box - I suspect the node-js and node-red version will probably be to old.
