Serial port selected dynamically from the dashboard?

For the moment you have to select it in advance in the editor, it would be convenient to be able to display the same choice from the dashboard and store this value in a global variable for example.

Hello, I also need this feature, do you find any solutions how to do it?

Hi, no idea how to do this and my post did not find any help.
Maybe we should ask the person who wrote this node?

Possibly because a quick search of the forum reveals that it is not possible at runtime. There are some work arounds involving env variables and restarting node-red but no dynamic runtime possibilities at this time.

I agree, the information should be loaded before the start of NR
