Beginner questions on IF expressions and wildcard usage in function node

The local storage is great and I might tackle it in version 2, but right now it is more versatile to listen to the sources live and process on the fly.

I will try your unsubscribe/subscribe chain again. I am just surprised I would need to split it into to mqtt nodes.

When I tried the getSubscriptions action I got an error message in the debugger (sorry, not at home, cannot post) and the debug node behind the mqtt node did not show any output.
