eufy Smart Lock E31
Score: 85/100Rankings

The eufy Security Smart Lock E31 is a versatile, hub-free smart deadbolt featuring Matter compatibility and fingerprint recognition. It offers excellent ecosystem integration with Apple Home, Google, and Alexa, along with a long-lasting 14-month battery life. However, it lacks Apple HomeKey support and relies on 2.4GHz Wi-Fi, which may be a limitation for some users.

The LockStar S110BBL-F is a feature-rich keyless deadbolt offering multiple entry methods including fingerprint, FOBs, and keypad. Its standout reliability comes from the sensor-based auto-lock and fast fingerprint scanner, though remote access is hindered by the need for an optional gateway. It is best suited for families and rental properties that prioritize local convenience and physical backups over immediate remote connectivity.
