Which devices qualify as a home hub in Apple’s Home app

Apple’s Home app gains an AI feature in iOS 27 that only works if a household already owns a specific piece of hardware Apple calls a home hub. Apple names exactly three devices that qualify: HomePod (2nd generation), HomePod mini, and Apple TV 4K.

The requirement appears in Apple’s own iOS 27 feature list, published around the same September 9 event that introduced iPhone 18 Pro and iPhone Duo without touching either HomePod or Apple TV hardware. iOS 27 itself arrives September 14, and this Home app change ships attached to hardware Apple already sells rather than anything new.

Key facts

What actually needs a hub, and what does not

Apple’s own materials draw a line inside the Home app that is easy to miss. Activity summaries, a feature that combines related activity notifications into a single update, carries no stated hardware requirement in Apple’s documentation. The second feature, which lets the Home app describe what happened in a stretch of HomeKit Secure Video footage before a viewer watches it, and search clips with a plain-language question, is the one tied explicitly to a home hub, an iCloud+ subscription, and an Apple Intelligence-enabled device, all three at once. Apple’s language also limits the video side to cameras that can already stream and record in 4K.

The three qualifying devices, and what Apple currently publishes about them

Apple’s own product pages describe two of the three hub devices in some detail, and effectively nothing about the third. HomePod mini runs Apple’s S5 chip and comes in five finishes: white, yellow, orange, blue, and midnight. Apple TV 4K runs an A15 Bionic chip, sold in 64GB Wi-Fi and 128GB Wi-Fi plus Ethernet configurations. Neither page carries a new colour, a new chip, or a new date tied to this year’s announcements; both are the same product pages that existed before September 9. HomePod (2nd generation) fares worse in the record available here: it is named as a qualifying hub in the iOS 27 feature list, and nowhere else in the material reviewed does its chip, price, or current colour lineup appear.

How much iCloud+ buys you

A home hub is only half the requirement. iCloud+ is the other half, and Apple ties the size of that subscription directly to how many HomeKit Secure Video cameras a household can run at once. Apple’s published tiers start at $0.99 a month for 50GB, which covers one camera, and step up from there.

Every tier at 2TB a month or above removes the camera limit entirely, according to Apple’s own iCloud+ pricing page. Apple has not published a version of the clip-description feature that works without a paid iCloud+ plan attached to it.

The camera Apple does not name

What Apple has not published is which cameras qualify. Its own language describes only “supported cameras” capable of streaming and recording in 4K, without listing a single model, brand, or generation. A household checking whether an existing HomeKit camera will gain clip descriptions and natural-language search has nothing more specific than that phrase to go on.

What Apple has not said

Apple has not published current specs, a price, or a colour lineup for HomePod (2nd generation) in the material reviewed here, despite naming it as a qualifying hub. It has not published a list of which HomeKit cameras count as “supported,” has not attached a refresh date to HomePod mini or Apple TV 4K, and has not said whether a future update will loosen the iCloud+ requirement for smaller households. Activity summaries carries no published hardware requirement at all, a contrast Apple has not explained.

As of September 12, iOS 27 is two days from its September 14 release, and every device named in this requirement is one Apple already sells. Whether Apple adds a named camera list, new hub hardware, or a lighter iCloud+ tier alongside it is not something the company has said.
