I agree with Kirk. I really like the feature as it allows us to organize connected devices for quick viewing of status. We just need more device types or the ability to create custom device types. This is especially true in a smart connected home.
I would need a custom type Bridge for the Home category. Lots of devices with bridges (e.g. Phillips Hue, Lutron Caseta, Ring Doorbells, August Smart Locks, Arlo Cameras. Would take out so many birds with a Bridge category for Home.
