Apple Home adds new smart lock with auto-unlock that’s hands-free
Schlage is launching the Sense Pro smart lock on June 29 for $399, introducing Ultra Wideband (UWB) technology to the Apple Home ecosystem. According to a company press release, the lock uses “Schlage Converge” technology to calculate a user’s speed, trajectory, and motion to enable precise, hands-free unlocking as they reach the door.
Why is Ultra Wideband replacing Bluetooth for smart locks?
Ultra Wideband (UWB) provides spatial awareness that traditional Bluetooth and GPS geofencing lack. While previous smart locks relied on proximity—often unlocking while the user was still in the driveway or failing to trigger entirely—UWB uses time-of-flight measurements to determine exact distance and direction.
Schlage states that its new Converge technology understands “intent to enter.” By analyzing how a person moves toward the door, the lock avoids accidental triggers. This solves a long-standing security flaw in Bluetooth-based proximity locks, which could be tricked by a signal-boosting attack or trigger simply because a user walked past the house.
How does the Schlage Sense Pro compare to the Aqara U400?
The Sense Pro enters a small market of UWB-enabled Apple Home locks. Currently, its primary competitor is the Aqara U400. The two devices differ significantly in pricing and targeted user experience.
| Feature | Schlage Sense Pro | Aqara U400 |
|---|---|---|
| Price | $399 | $269 |
| Primary Tech | UWB (Schlage Converge) | UWB |
| Connectivity | Matter over Thread | Apple Home/Aqara |
The $130 price premium for the Schlage model reflects its integration of Matter over Thread and Aliro compatibility, standards designed to make smart home hardware work across different brands without proprietary hubs.
What happens next for home automation standards?
The adoption of Matter over Thread in the Sense Pro marks a shift away from the “walled garden” approach. According to industry specifications, Thread is a low-power mesh networking protocol that reduces latency and removes the need for a central bridge for every device. This means the lock communicates directly with other Thread-enabled devices in the home.
Furthermore, Schlage’s inclusion of Aliro compatibility suggests a future where your car key or phone can unlock your house, office, and gym using a single unified standard. This mirrors the transition the automotive industry made toward digital keys, moving the logic from the lock itself to the encrypted token on the user’s device.
Will battery life suffer with UWB and Thread?
Higher precision usually requires more power, but Schlage claims the Sense Pro will maintain up to six months of battery life. This is largely due to Thread’s efficiency compared to traditional Wi-Fi, which drains batteries quickly by maintaining a constant, high-power connection to a router.
For users transitioning from older Bluetooth locks, the main difference won’t be the battery longevity, but the reliability of the “auto-unlock” feature. By using UWB to calculate trajectory, the lock remains in a low-power state until it detects a specific movement pattern indicating the user is actually approaching the door.
Frequently Asked Questions
Does the Schlage Sense Pro require a hub?
Because it supports Matter over Thread, it requires a Thread Border Router (like a HomePod mini or Apple TV 4K) to connect to the wider network, but it doesn’t need a brand-specific Schlage hub.
Is UWB more secure than Bluetooth?
Yes. According to technical documentation on UWB, the technology is resistant to “relay attacks” because it measures the actual time it takes for a signal to travel, making it nearly impossible to spoof a user’s location from a distance.
When can I buy the Sense Pro?
The lock is scheduled for release on June 29.
