Apple’s “second-party” LG accessories will debut another Home feature: Proximity Control. As with HomePod, tapping or bringing iPhone near the accessory shows a hint in the Dynamic Island. An “Open Controls” button opens the accessory’s controls. Cameras and doorbells show a camera viewer.

An iPhone without a Dynamic Island or an iPad will show a 30-second notification instead. You can disable this behavior in the Home app after setup. You’ll also see feedback in the Dynamic Island as iPhone launches setup when you first tap the accessory to pair it.

Behind the scenes, the accessory writes an “apple-deviceid” in the Matter payload stored on its NFC tag that helps iOS identify it when tapped. It also broadcasts a Bluetooth Low Energy advert for Apple Proximity Control.

• Never: Suppresses proximity controls.​ • Ask to Launch: ​Shows Dynamic Island hint or notification, which deep links the control card. • Launch Automatically: Shows control card.​

In the current implementation, the enabled state is equivalent to Ask to Launch. Home’s helper text reads: “Show controls when you bring your iPhone near your [accessory].” The feature is still in active development across beta releases, so the final behavior may change.
