Does the iPhone 18 Pro shortage affect your smart home?

No: the reported iPhone 18 Pro memory shortage should not block an Apple Home setup. As of August 25, 2026, the shortage is a Reported supply/timing issue; iPhone 18 Pro smart-home specifications are Unverified because Apple has not officially announced the phone; Thread support on the iPhone 18 Pro is Expected, not confirmed; and the Apple Home hub requirement is Confirmed in Apple's documentation. If your plan depends on automations, remote access, notifications, HomeKit Secure Video, sharing, or dependable Thread infrastructure, the purchase to verify or make first is an Apple TV 4K or HomePod-class home hub, not a scarce new iPhone.

An iPhone remains important, but it has a different job. It is the device you use to configure and control Home, add accessories, and perform local Matter or Thread pairing where supported. A home hub is the always-on household anchor that keeps services working when your phone leaves the house.

The Apple Home hardware map

Apple's current Home architecture separates the controller from the hub. Apple documents a home hub as necessary for remote access, automations, HomeKit Secure Video, and sharing a home with other people. Under the newer architecture, an iPad no longer qualifies as a home hub. [1]

That distinction matters during a purchase decision. A phone can be the screen in your hand without being the device that continues running the household after you take it to work. If a camera notification, scheduled light scene, or remote lock command must operate while no resident's iPhone is present, the system needs the hub path.

Thread adds another layer. Apple lists the iPhone 15 Pro, iPhone 15 Pro Max, and later models running iOS 18 as Thread-enabled for local pairing. Apple also notes that some battery-powered Thread accessories require a manufacturer firmware update before they can pair directly with a Thread-enabled iPhone. Automations, notifications, and remote control of Thread devices require a Thread-enabled hub or compatible border router. [2]

iOS 18 made hubless Matter setup more practical: compatible iPhones can add Wi-Fi Matter devices, while Thread-device support begins with the iPhone 15 Pro or newer. A hub is still recommended for automations and remote control. [3][4] In other words, local pairing support is not the same thing as a complete always-on Apple Home installation.

What the shortage actually changes

The reason buyers are asking is not imaginary. A report published August 5 said TSMC was holding approximately $1 billion of A20 Pro wafers while waiting for DRAM, with Apple reportedly sourcing memory mainly from Micron, SK Hynix, and Samsung. Those supply-chain details are reported by Culpium and are not independently verified here. [6]

Subsequent reporting described a narrower availability risk: Apple and its assemblers were expected to meet initial demand, but online order waits could lengthen and retail stock could dry up afterward. Another analysis said launch-day orders should be fulfilled without a launch delay, while follow-on delivery times could become longer because the memory is co-packaged at the wafer level and cannot simply be added later. [7][8]

That supports a timing concern for the phone. It does not support a missing Apple Home capability. Apple has not announced the iPhone 18 Pro as of this date, so its final memory configuration, Thread implementation, price, and availability remain Unverified. Reports also differ on possible pricing, with figures around $1,399 and $1,499 discussed, alongside larger increase rumors. There is no reliable wait-time number.

The wider memory market may add cost pressure. Digitimes, citing Morgan Stanley, reported that Apple had locked DRAM only through the first quarter of 2026 and that sequential memory prices had risen by more than 50 percent. IDC estimated memory at roughly 10 to 15 percent of a flagship phone's bill of materials in a scenario-based analysis. These figures describe supply and cost exposure, not a forecast of the iPhone 18 Pro's final retail price. [10][11]

Reported launch timing is similarly provisional. MacRumors cited expectations for an event around September 9, pre-orders around September 12, and sales around September 18; none of those dates had been announced by Apple on August 25. [12] Another report said the fall lineup would focus demand on the Pro, Pro Max, and Ultra models, with no base iPhone 18 or Air 2 shipping in the same window. [9]

Choose according to the Apple Home job

If you are starting from nothing before a move or renovation, secure the hub first. An Apple TV 4K or qualifying HomePod gives the home a persistent control point; your current compatible iPhone can then commission accessories and manage the setup. Check the exact Apple TV model when Thread border-router support matters, since that capability is model-dependent. The guide on which Apple TV 4K model works as a smart-home hub is the relevant verification before ordering.

If you are adding Matter or Thread accessories to an existing home, first identify the phone and hub already in the chain. An iPhone 15 Pro or newer on iOS 18 can cover the supported local Thread-pairing role. That may be enough to get an accessory into the Home app, but it does not replace a qualifying hub for remote control, automations, notifications, or shared access.

If remote access and automations are the reason you are building Apple Home, a new phone cannot substitute for the hub. The same applies to HomeKit Secure Video and a household where multiple people need access. Verify the hub in the Home app and confirm that it is signed into the intended Apple account before diagnosing the phone's availability as the problem.

The upgrade case is narrower. Moving from an older iPhone can make sense for general performance, software support, or a phone feature you specifically need. It is not necessary merely to unlock the Apple Home behavior already available on an iPhone 15 Pro or newer running iOS 18. The reported iPhone 17 lineup's Thread support reinforces that the newer generation is expected to continue the same direction, but it does not turn the reported iPhone 18 Pro into a required component. [5]

For a phone you already own, the practical decision is simple: keep it if it meets the iOS and accessory requirements, and spend the budget on missing hub hardware. For a phone you intended to buy anyway, the shortage affects when and where you may obtain it, not whether your Apple Home project can begin.

What to do before ordering

• Confirm that the iPhone used for setup is an iPhone 15 Pro or newer if your accessories require direct Thread pairing, and update it to iOS 18 or later.
• Confirm that the accessory supports Matter or Apple Home and check whether a battery-powered Thread device needs a manufacturer's firmware update.
• Buy or verify an Apple TV 4K or HomePod-class hub if you need automations, remote access, notifications, HomeKit Secure Video, sharing, or reliable Thread operation.
• Do not count an iPad as the home hub under the current Apple Home architecture.
• Treat every iPhone 18 Pro specification, price, and launch date as unconfirmed until Apple publishes it.

For the hub role itself, see Can the iPhone 18 Pro Max be your smart home hub? as a companion verification. The Apple TV 4K hands-on guide covers the dated Thread and hub details, while Apple TV 4K: buy now or wait addresses the purchase timing question directly.

The dated recommendation is unchanged: do not delay an Apple Home setup, or panic-buy an iPhone 18 Pro, because of the reported memory shortage. If you already have an iPhone 15 Pro or newer, you have the key local pairing capability Apple added in iOS 18. Put the availability-sensitive decision on the hub: verify or buy the Apple TV 4K or HomePod path that will keep the home running after the phone is out of your hand.
