Hey there, not a Lovelace setup, but I tried to create a mobile app version with 3D model which you can actually use it for fully navigating around and control your stuffs from 3D interface 
Some more screenshots here:
I added more detailed information at 3D App for Home Assistant - Unity, RestAPI, MQTT post as I cannot make it long in this thread. This is my hobby project, but really excited to see it can integrated with HomeAssistant!!
Could you give me what you think about this? Thanks guy!
