We’ve looked at doing this, and know that’s it’s doable. It’s basically making the stick act like a secondary controller to ST, which gets all of the z-wave devices downloaded to it. There is one significant problem however, and that is the who’s-on-first problem. It appears that the way you’ve done this leaves the stick as a secondary controller to ST. Have you determined that it all works in Hubitat if you turn off the ST hub? If both hubs are on, then either can control those devices, and when doing so, the other hub will not know that has happened, leading to out-of-synch problems for automations.
