Hi guys,

Like your ideas on a good and secure automation in home assistant using the U200 lock.

Hi and welcome to the forum.

You can use the U200 in conjunction with a camera, such as a G5 Pro or a doorbell camera like a G410 at the entrance. Then configure facial recognition in the Aqara Home app as a Matter signal and add the doorbell or camera as a Matter bridge in Home Assistant.

Home Assistant, in combination with the Home Assistant Companion app for iOS or Android, can detect your location (presence at home). You can then combine both in an automation: If a face is recognized and a person is present, unlock the door.

Since 2D facial recognition is less secure, this approach increases security because your smartphone must also be near your home. Additionally, the door only opens when you are standing directly in front of the door (camera).

I don’t have a smart lock, but this blueprint for Aqara locks and voice assistant announcements seems pretty good:

github.com/zodyking/Locks-Contact-Sensors-Presence-Sensors-Blueprint-Pack

locks.yaml

main

blueprint:
  name: "Aqara: Locks"
  description: |-
    ![Aqara](https://raw.githubusercontent.com/zodyking/Locks-Contact-Sensors-Presence-Sensors-Blueprint-Pack/refs/heads/main/locks.png)

    Locks-only automation with optional spoken announcements, a “still unlocked” reminder loop,
    optional actions on lock/unlock, and time-based auto-lock. Built for reliability and clear speech.

    What it does
    • Speaks LOCKED/UNLOCKED (only after real, confirmed state changes).
    • Optional reminder: repeats a message every X seconds while the lock is UNLOCKED
      until it’s locked (stops immediately when fixed).
    • Optional actions: turn on entities when the lock UNLOCKS; turn off entities when the lock LOCKS.
    • Time-based auto-lock: re-lock after X seconds whenever the lock becomes UNLOCKED.
    • All speech is queued (mode: queued, max: 2) with a small TTS pre-roll to prevent clipped words.

    Setup
    1) Select the lock.
    2) (Optional) Pick announcement mode (None or Lock).
    3) (Optional) Pick reminder mode (None or Unlocked) and interval.
