Smart lock comparisons: WELOCK and Aqara models

Various smart lock models from WELOCK and Aqara offer different solutions for home automation and keyless entry.

WELOCK provides three primary models: the ToucA51, which offers basic access via fingerprint, PIN, RFID, or Bluetooth; the ToucA51 Pro, which adds the ability to generate temporary access codes for guests or short-term rentals; and the U81, which includes a mechanical backup key. The ToucA51 series can be integrated with Wi-Fi via a separate gateway for remote unlocking and voice assistant compatibility.

Aqar offers the Smart Lock U200 Lite, a budget-friendly option designed to fit onto existing cylinders without requiring a full hardware replacement. While it lacks a keypad and fingerprint reader found in its full-sized counterpart, it supports Matter over Thread for smart home integration. The device is noted for its ease of installation and ability to retain the use of traditional keys, though it is noted for having a noisy motor.
