Does Apple Home need a hub?

No, not to get started, and yes, for the things most people buy smart accessories to do. That split is the honest answer, and it is worth getting exactly right, because the wrong version of it sends you to the shops for a box you may not need yet.

The box in question is a home hub, which in Apple's world means a HomePod, HomePod mini or Apple TV 4K. On the box or in an older forum post you will often see the same thing called a HomeKit hub; same device, older name. What it is for is the part Apple's own pages muddle.

What works with no hub

If you have an iPhone running iOS 18 or later, you can add Matter accessories to the Home app, and control them, with no hub in the house. That is Apple's own statement. On an iPhone 15 Pro or later, Thread accessories can be controlled without a hub too, and any HomeKit accessory you have already paired can be controlled locally the way it always could.

Apple never publishes the hubless list in one place, but assembled from its pages a hubless household keeps: adding and locally controlling Matter accessories, local control of paired HomeKit accessories, manually triggered scenes, and Siri on the phone for accessories on your network.

That is a real configuration, not a crippled one. If all you want is to tap your phone at home and have the lights respond, you can stop reading and spend the hub money on another accessory.

What a hubless home gives up

The right column is why our own product pages treat a hub as part of a working Apple Home setup. Not because your accessory will fail without one; it will pair and work. Because nearly everything people actually buy a smart accessory for, the schedule that runs while you sleep, the notification when the door opens, the camera clip from the school run, sits in that column.

Two rows need their sources stated. For Thread accessories, Apple says it plainly: to use automations, get notifications or remotely control Thread-based accessories, you need a Thread-enabled home hub or a compatible third-party Thread border router. For automations across every accessory type, Apple states that automations require an Apple TV or HomePod acting as a home hub; that sentence lives in a footnote on Apple's Home page, so we pass it on as Apple's claim rather than asserting it, and we plan a home as if it is true.

Apple disagrees with itself here

Multiple hubs, and who controls them

A home can have more than one hub. Apple elects the active one automatically, and you can turn off Automatic Selection in the Home app and choose a preferred hub yourself. Only the home's owner can add a hub, or any HomePod or Apple TV, to the home; invited users cannot, even those allowed to edit accessories.

Apple does not publish how the automatic election chooses between hubs, or what happens when the active hub drops off the network, so we will not guess here.

If you decide you want one

Which device to buy is its own question, with a twist worth knowing about before you pay: the hub list and the Thread border router list are not the same list. The short version is that the HomePod mini at A$199 is the cheapest device that does both jobs, and the A$299 Apple TV 4K (3rd generation) Wi-Fi model, often recommended as the cheap way in, routes no Thread at all; only the Wi-Fi + Ethernet variant does.
