With the introduction of the new operating system generation around iOS 16 and iPadOS 16, there will probably be a major change. According to previous information, the iPad will no longer be able to be used as a HomeKit control center with the introduction of matter. Only the HomePod as well as the Apple TV should fulfill this task, reports heise.
However, there is still some hope. So far, the decision at Apple does not seem to be final. Despite the exclusion of the iPad as a control center, there is still a selection button in beta 1 of iPadOS 16 that allows the device to be used as a home hub. So there might still be hope that the tablet can be used as a Home Hub, but then without matter support.
