Structural analysis of the Sifely S1 confirms a Grade 3 consumer build with a 500 DPI capacitive fingerprint scanner. The motor drive consists of a high-torque DC micro-motor and a standard nylon clutch mechanism. This hardware is natively Bluetooth Low Energy (BLE) and requires the Sifely G2 Gateway for protocol translation to Wi-Fi for remote access and third-party integration.
Technical documentation indicates the device can store up to 200 fingerprints locally and generate time-sensitive offline passcodes. Material specifications list an IP54 rating, and the design includes a hidden key cylinder for mechanical override. Operational insight suggests that mechanical binding in the strike plate is a primary cause of nylon gear stripping and motor failure over time.
The eufy Smart Lock C33 provides an alternative for those seeking a lock with integrated Wi-Fi and higher-grade motor components.
This lock is a specialized unit within the smart keypad and biometric entry classification.
