Node-Red's serialport module is outdated. How do you update it?

You probably won’t see anything about that combination because the interface between NodeRed and OH is pretty well defined. For the most part the two are completely separate. There is very little you can do to NodeRed that will cause problems with OH.

So take a backup and do whatever the instructions tell you to do to upgrade that part of NodeRed.

Obviously, take a backup first.
