6 harmony hubs, something like 50 activities each of which are virtual devices in smartthings. Lots of virtual switches that I used as restrictions for automations (like my lights come on based on motion in the kitchen unless Time to eat is on, then the lights just stay on), I have momentary button tiles i use to run routines, I use the smart app called Trendsetter that groups multiple devices together and makes just one device, virtual switches or buttons that I use to tie things into habitat, virtual switches that turn on based on my teams playing that turn LED strips certain colors. There's probably more, but those are what I've got off the top of my head
