@RHCPNG As @toggledbits notes, I've found myself bouncing around a bit. I've settled on what I call Shared Rules - those that impact all things potentially, at a base level. Wx stuff, HVAC stuff, etc.
I kinda branch out from there. Interior lighting, Outdoor lighting, Presence, etc. Sorta using "topics" and then rulesets under them.
I'm also linked to our local community center via site-to-site VPN and am using my home MSR instance to control the Hubitat C7 over there for lighting and outdoor fans 🙂
