Welcome!
Depending on what you do, the device handlers (especially custom ones) you use, and some SmartApps, Classic may be more appropriate for your use case. New new app will probably work for you, but I think Classic may work better for you.
I used those at one time, but not like what you want to do with them. I can’t recall if anyone has done that either. I’ll search the Community a little later tonight to see what I can find.
My advice is to be patient, especially with the differences between the new app and Classic, and which one to use to get your hub set up. We’re all here to help.
I’m also a boater, so I’m curious to see what you come up with!
