The August Home Smart Lock Pro + Connect Hub is a versatile retrofit lock with extensive smart home compatibility, including Z-Wave and HomeKit. It offers easy installation and robust automation features but relies on a separate bridge and AA batteries. It is ideal for smart home enthusiasts with diverse ecosystems.

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.
