Very interesting to see there is a request for this since 2015. It’s now 2020, and I just want to let you know that we are a team that working on a companion app for SmartThings, which we call ThingsTwin dashboard. It’s based on 3D interface and it based on your own unique floor plan. You can see more information in this thread [ALPHA] ThingsTwin 3D App: Brand New Way to Play with Your Home - View and Control from 3D Floor Plan or just visit our home at thingstwin.com
Thanks & have fun, fellows!
