[Feature Request] Migration path to the new SmartThings App (?)
**Is your feature request related to a problem? Please describe.**

This has been coming for a while now, but it looks like Samsung is finally pulling the plug on the SmartThings Classic app, and therefore its Marketplace which this plugin relies upon.

Quoting recent communication from Samsung:
> SmartThings Classic will be discontinued on October 14, at which point you will be unable to use or access the application.
