August Smart Lock 2nd Gen Silver
Score: 72/100
Ultraloq Bolt
Score: 90/100Rankings
The ULTRALOQ Bolt Fingerprint WiFi Smart Deadbolt is a Matter-over-Thread smart lock featuring 8-in-1 keyless entry and robust ANSI Grade 1 security. Its main limitation is the 2.4 GHz WiFi restriction and lack of Micro-USB backup power. It is best suited for Apple Home users seeking native Siri integration and multi-ecosystem homes.
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.
