There are lots of great smart locks out there. But one of the best models that iPhone owners should consider buying right now Aqara U400Which provides hands-free unlocking when you get close enough. It has Apple’s U1 ultra-wideband chip integrated into it to authenticate you and unlock the door hands-free, so all you have to do is open the door when you get home. This smart lock is discounted for the first time during the Big Spring Sale, priced at $229.49 (originally $269.99) at Amazon.
As our reviewer Jennifer Pattison Tuohy said in her hands-on experience with the U400, hands-free unlocking is nothing new – but it’s the most reliable implementation we’ve tried so far. Apple’s Home Key relies on a mix of Bluetooth and UWB to connect and authenticate, and you don’t need any additional apps.
In addition to using the Home key, you can unlock the U400 with a code on its touchscreen keypad, via a registered fingerprint, or with a regular ol’ key. This is a miter-over-thread lock, and it works with the smart home ecosystem of your choice. All you’ll need is a Thread border router (recent Apple TV models, the second-generation HomePod, and the HomePod mini are some examples of border routers at varying prices) so that your devices can communicate entirely over Thread instead of Wi-Fi, saving the doorbell’s battery.
