Aqara U400 Lock

I installed the Aqara U400 because I wanted true frictionless entry, and the UWB approach-to-unlock absolutely delivers. It’s loaded with options (keypad, fingerprint, NFC, Apple Home Key) and it’s future-leaning with Matter over Thread for fast local control. Just keep in mind some advanced features still require the Aqara app since Matter is still maturing.

Pros

+UWB hands-free unlock is instant and accurate
+Matter over Thread enables fast local control and automations
+Multiple unlock methods: key, keypad, fingerprint, NFC, Apple Home Key
+Rechargeable battery pack (no disposable batteries)

Cons

-Some advanced features (like fingerprint management) aren’t exposed over Matter
-May require a Thread border router for full Thread/Matter benefits
