2026 verdict

Aqara Smart Lock U400 wins on weather resistance, connectivity, integrations, unlock methods and password features. Its outer panel is rated IP65 versus IP53, it speaks Bluetooth, Thread, UWB and NFC, reaches Apple HomeKit, Home Assistant and Matter (plus Google and Alexa via an Aqara hub), and offers fingerprint, keypad, NFC, Apple Home Key and hands-free UWB entry with one-time and periodic passwords. Wyze Auto-Lock Bolt v2 answers with a far lower price, a higher owner rating and about 8 months of AA battery life versus 6 per charge, plus its crowd-pleasing half-second AI fingerprint reader and simple Wi-Fi app control, though it has no HomeKit, Matter, NFC or Thread. Both auto-lock and use anti-peep keypads. As a smart home lock, the Aqara Smart Lock U400 plays in another league; as cheap dependable fingerprint entry, the Wyze endures.
