August Smart Lock Wi-Fi Silver
Score: 76/100
Aqara Smart Lock U100
Score: 75/100Rankings

The August Wi-Fi Smart Lock (Silver) adds built-in Wi-Fi, DoorSense and voice-assistant control while preserving the original deadbolt. It lacks auto-lock and detailed battery-life information. Best for users who want a simple retrofit with remote access and don't need advanced automation.

The Aqara Smart Lock U100 delivers high-accuracy fingerprint unlocking, Apple HomeKey compatibility, and IP65-rated weather resistance via Bluetooth, Zigbee, and NFC. It requires an Aqara hub for full smart-home functionality and is relatively heavy, which can complicate installation. Suited for users invested in the Apple ecosystem and needing strong outdoor durability.

Professional reviewers commend the U100 for its precise fingerprint sensor, Apple HomeKey compatibility, solid auto-lock functionality, and impressive eight-month battery life. They also note the lock's robust zinc construction, IP65-rated outer panel, and reliable Zigbee performance when used with an Aqara hub, while calling out the need for a hub for full feature access and the non-weather-proof inner panel.
Everyday users generally praise the lock's versatility, long battery life, and weather-resistant outer housing, especially valuing the multiple unlock options and local data security. Recurring complaints focus on the requirement of an extra hub for advanced smart-home features, the inner panel's lack of weatherproofing, and the relatively heavy weight during installation.
“HomeKit News praises the U100 for its fingerprint sensor, Apple HomeKey support, auto-locking, and 8-month battery life, noting solid Zigbee 3.0 performance with an optional Aqara hub and IP65 outer panel for weather resistance.”
