@BTheSmartHomeNoob Right now, hands‑free (UWB) unlocking on the U400 is tied specifically to Apple Home Keys, and that setup requires an Apple Thread-enabled Home Hub (Thread Border Router) in your Home—there isn’t anything in the current behavior/docs that suggests it can be done “hubless” on iPhone/Apple Watch via a generic Matter hub. To pair U400 with Apple Home in the first place, an Apple Home Hub with Matter support + Thread Border Router is required.
For the UWB part specifically: UWB hands‑free is enabled as part of Apple Home Key Express Mode (“Unlock on Approach”) during Apple Home setup (and can be toggled later in the iOS Wallet key settings). And the U400’s third‑party feature list also frames “UWB unlock” as something you get when you have a 2‑in‑1 Matter Controller + Thread Border Router in the ecosystem.
So… will a future software update remove the Apple hub requirement for iPhone hands‑free?
Based on the reference info we have here: there’s no confirmed path that would let iPhone/Apple Watch do Apple Home Key UWB hands‑free unlock without an Apple Thread Home Hub. The “hands‑free with iPhone/Apple Watch” experience you’re aiming for is an Apple Home Keys feature, and Apple’s architecture still expects a Thread-capable home hub for Matter/Thread accessories.
Practical takeaway for your setup
- If your Apple TV model doesn’t provide Thread, the most reliable way to get iPhone/Apple Watch hands‑free (UWB) with Apple Home Key is still: add a supported Thread home hub (e.g., HomePod mini / HomePod / supported Apple TV model with Thread).
- Using a Matter-compatible hub alone (non-Apple) may cover other remote/control features, but it doesn’t replace Apple Home Key’s requirements for UWB hands‑free on iOS.
