August Home vs Sifely Lock Comparison
Installation style
The August Home Smart Lock Pro is designed to attach directly to the interior side of your existing deadbolt. This means you keep your current keys and exterior hardware intact. The Sifely Fingerprint Smart Lock replaces your entire door handle and deadbolt assembly. It includes a new handle and fits most standard doors without extra drilling. If you prefer not to change your exterior door hardware, the August model is the better fit. If you want a complete hardware refresh with a new handle, the Sifely unit provides that.
Access methods
You unlock the August Home lock using the app, auto-lock features, or your existing physical key. It does not list fingerprint or keypad options in its specs. The Sifely lock offers five distinct ways to enter: fingerprint, keypad, app, FOB, or key. This variety is helpful for families with children or elderly users who may struggle with small keys. The Sifely approach provides more physical entry options, while the August Home relies on digital commands and your traditional key.
Connectivity type
The August Home Smart Lock Pro includes a built-in Connect Hub for Wi-Fi connectivity. This allows you to monitor and control the lock from anywhere without needing an extra device. The Sifely lock uses Bluetooth as its primary connection method. It requires an optional Sifely WiFi Gateway to enable remote access from outside your home range. If you want immediate remote control without buying separate hardware, the August Home model has the advantage. The Sifely unit may require an additional purchase for full remote features.
Smart home compatibility
Both smart locks support integration with major voice assistants. The August Home model works with Alexa and Google Assistant. The Sifely lock also supports Alexa and Google Assistant for voice control. However, the Sifely lock requires the WiFi Gateway to enable these voice commands and remote app features. The August Home lock includes the necessary Wi-Fi hub in the box for this functionality. Both offer similar smart home ecosystems, but the August Home includes the required connectivity hardware while Sifely may not.
Physical dimensions
The August Home lock is a compact unit measuring 2.22 inches wide, 3.4 inches high, and 3.4 inches long. It weighs 13.9 ounces. The Sifely lock is a full handle assembly with a knob size. It measures 3 inches wide, 1.12 inches high, and 7 inches long. It weighs 6 pounds due to the included metal handle. The August Home is much lighter and takes up less space on your door. The Sifely unit is heavier and replaces the entire door hardware structure.
