This is my situation as well right now with a couple roofs and I use multiple Wyze products everywhere here but so far I’ve managed. I would though like to be able to create a “Group” in the app that isn’t device specific and can contain a mixture of “Device Groups” within.
Nesting? Is that the correct terminology? Lol. If some form of generic Nesting was an option then various parcels/buildings aren’t an issue. Neither is various anything actually. Then we can even break the Wyze gear down into Rooms as example and have different Device Groups in that Room/Building/Parcel/Shed/Lanai/gazebo/whatever. That’s what I would appreciate if they can get to it sometime…
I wonder if that’s in the Wishlist or Roadmap category? Just saw that was a thing here. 
I’ll have to check. Just started becoming more entrenched in the Wyze gear…
