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 DESLOC B200 is a WiFi-enabled smart deadbolt lock offering keyless entry via fingerprint, PIN codes, app, eKeys, IC cards, and mechanical keys. It features rapid 0.3-second fingerprint recognition, customizable auto-lock, and IP54 weather resistance, with optional remote access and voice control through a separate G2 Gateway. While it offers high user capacity and long battery life, the need for an additional gateway for remote features is a significant trade-off.
