Score: 72/100
Wyze Palm Lock
Score: 85/100Rankings

The Wyze Palm Lock is a biometric smart door lock that utilizes palm vein recognition technology for contactless entry, replacing standard single-cylinder deadbolts. It offers multiple unlock methods including PIN codes, mobile app control, voice assistants, and a physical key backup, while featuring a dual-battery system for reliability. The device is positioned as a biometric-first device representing a shift toward ultra-personalized, biometric-first home security.

The August Home Smart Lock 2nd Generation is a retrofit smart lock that fits on the interior side of most single-cylinder deadbolts, preserving the existing key while adding app-based control. It requires a separate Wi-Fi bridge for remote access, which is a notable trade-off for users wanting immediate out-of-the-box connectivity. It is best suited for Apple HomeKit users and renters who want a non-destructive smart lock upgrade.
