Sifely S Fingerprint Smart Lock with Handle

The Sifely S smart lock combines fingerprint, keypad, Bluetooth app, RFID fob, and mechanical-key access in a handle-style lock. Its standard model uses local Bluetooth, while remote internet control and voice features require a separately sold Wi-Fi Gateway. The listing reports mixed feedback on fingerprint recognition and reliability, so consider that alongside its flexible access options.
