HomeKit’s Home app on iOS
HomeKit is giving users more choice about what controls the smart home network in iOS 18, by selecting what device acts as the active Home Hub.
HomeKit prefers to have a Home Hub, a device designated as the main point of contact on the network for all other hardware. A home could have multiple devices that can act as the Home Hub, but you couldn’t previously designate one as the primary device for the task.
In practice, this meant that the assignment rotated, sometimes to a device on the periphery of your network.
For users, the option to select a Preferred Home Hub can be useful. For example, they can set newer devices as the designated Home Hub instead of older hardware.
