I think the main use case is avoiding non-open source alternatives.
If you want something that actually offers more capability then something like node-red is probably more useful, it allows scripting all kinds of custom behaviour over many different protocols. (although even then it's rare to find a real use for it, besides having fun hacking things together, though they make it easy to build your own UI for stuff, which is neat)
