HomeKit Accessory Grouping
Apple has also refined some of the organizational and grouping options for HomeKit accessories. You’ll find the new options in the Home app on your iOS device, as long as it’s running iOS 13.2.
Essentially, you can now group HomeKit devices with multiple functions as a single tile. You can also ungroup them to show their specific functions in individual tiles. It’s worth noting that, as of iOS 13, the single tile option is the default.
