Material analysis of the Sifely Smart Lock identifies a high-torque DC motor designed for 2-1/8 inch deadbolt bores. FCC ID 2ATY4-S1 filings reveal a Texas Instruments Bluetooth Low Energy (BLE) System-on-Chip (SoC), which prioritizes power efficiency over mesh network integration. Biometric verification is handled via a 508 DPI capacitive scanner, though performance metrics show throughput degradation in environments with high moisture or extreme low temperatures.
Technical specifications indicate that fingerprint data is stored locally on the device rather than in cloud databases. Remote management, including Alexa and Google Home integration, is dependent on the Sifely G2 Gateway to bridge the 2.4GHz gap. The hardware includes a physical key override and a micro-USB port for emergency power input. Long-term reliability reports suggest that oil-rubbed bronze finishes may experience pitting when exposed to high-salinity coastal air.
For users who prefer a lock with native Wi-Fi integration and no requirement for an external bridge, the eufy C33 offers a more integrated network stack.
This unit is a component of the biometric deadbolt hardware group.
