Last time I checked that wasn't officially supported...and obviously a pretty big resource hog (yep, there is a tradeoff). Plus separate servers and stuff.
Honestly though...if you really want to start writing rules that are getting complicated...just start writing groovy...in some ways...it's actually easier/faster than RM4.0. It's also editable so there aren't all these clicks and drops downs and stuff.
leave RM4.0 for the rules that fit it. Plus once you start writing your own apps, it's copy paste quick to take code from a previous project. It's not that hard. In fact...A thread or spot with some good basic apps to get people started would't be a half bad idea. The staff at HE show examples all the time...like this one:
I used to start an MQTT driver for my garage door...sometimes it just takes a little help to get started.
