Is this a Wi-Fi-enabled smart lock?

No. It utilizes the Matter over Thread networking protocol and requires a compatible Matter-and-Thread-enabled hub for network integration. Note: Each hub works only with its own app. Example: Apple Home Key requires the Home app and Apple hubs.

Why can't my U300 pair with the app (non-Aqara app)?

Check the following: • Use a Matter-over-Thread hub; • Enable IPv6 on your Wi-Fi; • Phone and hub on the same Wi-Fi; • Bluetooth turned on; • Lock within 5 m of the hub with no obstruction; • Press the Set button before pairing;

Can the handle of the Aqara U300 be reversed?

Yes, the handle can be reversed. Please watch our instructional video carefully before attempting, as incorrect installation may cause a loose handle or affect certain functions.

How do I know if this will fit my door?

The lock fits doors with a 2 3/8" or 2 3/4" (60–70mm) backset, 1 3/8"–2 11/64" (35–55mm) thickness, and a 2 1/8" (54mm) hole. If your door has two boreholes (typically for separate deadbolt and handle), a deadbolt-style lock may be more suitable.

Can the Aqara U300 be used on outdoor doors?

We do not recommend exposing the product directly to rain or snow. If used outdoors, it must be installed under a covered entrance (e.g., a porch or awning).
