Aqara Smart Lock U400 vs Schlage Arrive

Ultra-wideband unlocking that senses your iPhone as you approach is the standout trick on the smart lock winning this comparison, the Aqara Smart Lock U400, which also leads on connectivity, integrations and its unlock system against the Schlage Arrive. It adds Bluetooth, a Thread border router connection, UWB and NFC, reaches Apple HomeKit, Home Assistant and Matter natively (Google Home and Alexa need an Aqara Hub), and backs its touchscreen keypad, fingerprint reader, NFC and Apple Home Key with one-time, periodic and anti-peep guest passwords. The Schlage Arrive is the simpler, more established alternative: a push-button US deadbolt with only 2.4 GHz Wi-Fi and no Thread, Matter or biometric entry, trading cutting-edge tech for a design many buyers already know. Both keep a physical key as backup, though only the Aqara Smart Lock U400 adds a USB-C emergency power port and a published IP65 weather rating. Apple Home households chasing the newest hands-free unlock experience should go with the Aqara Smart Lock U400, while buyers who want a proven, straightforward push-button deadbolt without extra hubs should stick with the Schlage Arrive.
