Leaked code ties unpowered pairing setup on Apple's LG devices to HomeKit
Apple's co-developed LG home devices will show iPhone controls in the Dynamic Island on a tap, leaker pdfu found in iOS 27 code. MacRumors reported a HomeKit-only setup that starts before power is on, so Apple's software handles the first step of installing an LG lock.
The Product Desk
What happened
- Bloomberg first reported the LG-branded range this week, listing a thermostat, a deadbolt lock and several security cameras among products Apple reportedly co-developed.
- MacRumors contributor Aaron Perris spotted the Dynamic Island references in iOS code earlier this week, before pdfu detailed how the feature works.
- On iPads and on iPhones without a Dynamic Island, the shortcut appears as a notification that stays on screen for 30 seconds.
- Bloomberg says Apple likely won't release the accessories for at least a few more months, though they could appear at next week's Welcome home event.
Why it matters
- What it limits constraint Homes on another Matter controller can still pair the LG hardware after power-on, but only HomeKit households get the tap-before-power setup.
- Who's exposed exposure Network credentials land in the lock's secure element on the first tap, before the device runs, so a security review has to cover the NFC chip as well as the app.
- What it sets up precedent If it ships as found, LG's applet swap is a working template for putting Apple-only setup and controls inside another brand's Matter hardware.

The person fitting one of these LG deadbolts may not need to wait for it to switch on. MacRumors, reporting pdfu's findings, says an iPhone tapped against the unpowered accessory sends the phone's pairing identity and the home's network credentials over NFC into the device's secure element [9]. Once it has power, the accessory joins Wi-Fi or Thread and a home hub finishes Matter setup [9]. Firmware for the lock and the thermostat identifies that secure element as an NXP SE051H [16].
iOS 27 already supports the standard Matter version of NFC setup [14]. LG's hardware does not use it. Pdfu says LG replaces the secure element's Matter NFC applet with a HomeKit applet, so the before-power route works only with HomeKit [14]. Conventional Matter pairing is still available once the accessory is powered on [15].
Control works the same way. Each accessory writes an "apple-deviceid" into the Matter payload stored on its NFC tag so iOS can identify it on a tap, and it broadcasts a Bluetooth Low Energy advert for Apple Proximity Control [8]. So the payload uses Matter's format but carries an Apple identifier [8]. Pdfu compares the tap behavior to HomePod's [5]. 9to5Mac described Proximity Control as a clear example of a feature that will be unique to what it called second-party accessories [17].
Early iOS 27 code let controls open the instant a phone came near, with a Launch Automatically setting next to Never and Ask to Launch [7]. By iOS 27.2 the three options had become an on/off toggle. On is now equivalent to Ask to Launch, which shows a Dynamic Island hint or notification that the user taps to reach the control card [7]. The Home app also lets people switch the feature off after setup [12].
How users respond to the prompt is not yet known. Bloomberg says the accessories likely won't be released for at least a few more months, so there is no retention or usage data [11]. Pdfu wrote: "The feature is still in active development across beta releases, so the final behavior may change." [10]
For an operator buying these for homes or rental units, the decision turns on which controller runs the site and whether the device gets set up before or after it has power. Only a HomeKit site setting up before power gets the tap-to-provision route [9][14]. After power, a HomeKit home still gets Dynamic Island feedback on the first tap and the Proximity Control shortcut later [6][1]. On another Matter controller, the device waits for power either way and pairs the conventional way [15].
What to watch
- Whether Apple shows the before-power tap setup at the Welcome home event; a demo would confirm the HomeKit applet made it into shipping firmware.
- Whether the release build keeps Ask to Launch as the enabled state for Proximity Control or brings back Launch Automatically.
- Whether the before-power route opens to standard Matter NFC, or other brands ship the same HomeKit applet in their own hardware.

Leaker pdfu says Apple's 'second-party' home accessories co-developed with LG will support a 'Proximity Control' feature: tapping or bringing an iPhone near one shows a Dynamic Island notification with an 'Open Controls' button for accessories like thermostats, and a camera viewer for cameras and doorbells.

Bloomberg revealed the upcoming LG-branded accessory range earlier this week; the lineup reportedly includes a thermostat, temperature sensor, deadbolt lock, wired video doorbell and several security cameras, and Apple apparently co-developed the accessories.

Bloomberg first reported Apple's collaboration with LG earlier this week, detailing smart home products including a thermostat, deadbolt lock, indoor security camera, outdoor security camera and flood light camera.

MacRumors contributor Aaron Perris identified the Dynamic Island references earlier this week.

As with HomePod, tapping or bringing an iPhone near the accessory shows a hint in the Dynamic Island.
- [6]
Tapping a device for the first time will produce Dynamic Island feedback as setup begins.
- [7]
The feature has appeared in code since iOS 27.0. Earlier versions offered three options (Never, Ask to Launch, Launch Automatically) instead of the on/off toggle in iOS 27.2; in the current implementation the enabled state is equivalent to Ask to Launch, which shows a Dynamic Island hint or notification that deep links the control card.
- [8]
The accessory writes an 'apple-deviceid' in the Matter payload stored on its NFC tag that helps iOS identify it when tapped, and broadcasts a Bluetooth Low Energy advert for Apple Proximity Control.
- [9]
Pairing can start while an accessory is unpowered: an iPhone transfers its pairing identity and network credentials into the accessory's secure element using NFC, and when the device receives power it connects to Wi-Fi or Thread so a home hub can finish Matter setup.
- [10]
The feature is still in active development across beta releases, so the final behavior may change.
- [11]
According to Bloomberg, Apple likely won't release these accessories 'for at least a few more months'; they could still be shown at next week's 'Welcome home' Apple event.
- [12]
A setting in the Home app will let users switch proximity controls off after configuring the accessory.
- [13]
On iPads and iPhones without a Dynamic Island, the proximity interaction uses a notification that remains visible for 30 seconds.
- [14]
Pdfu says the unpowered setup method will be exclusive to HomeKit; LG replaces the secure element's Matter NFC applet with a HomeKit applet, even though iOS 27 also supports standard Matter NFC.
- [15]
Conventional Matter pairing will remain available once the accessories are powered on.
- [16]
Firmware for the LG lock and thermostat identifies an NXP SE051H Secure Element.

9to5Mac wrote that Proximity Control is 'a clear example of a feature that will be unique to these so-called "second-party" accessories.'
