SwitchBot Lock Ultra Review: Why I Replaced My Aqara U200 (Face Recognition + Home Assistant)

I’ve been using the Aqara U200 smart lock for a while and I was mostly happy with it… until one issue kept coming back: auto-lock wasn’t reliable. Sometimes the door simply stayed unlocked. I “fixed” this using Home Assistant automations to check lock status and correct it — but honestly, that shouldn’t be necessary for a premium smart lock.

So when SwitchBot sent me the SwitchBot Lock Ultra (plus the Keypad Vision), I was especially curious about two things:

Would auto-lock finally work flawlessly?
Would facial recognition be fast and secure?

Spoiler: I’m no longer using the U200.

What’s in the Box?

The Lock Ultra package includes a surprisingly complete set:

SwitchBot Lock Ultra (feels sturdy and premium)
Hub Mini (included by default)
Rechargeable main battery (no AA battery hassle)
Built-in backup battery (charge the main battery while the lock keeps working!)
Standard keypad with fingerprint scanner and NFC card support
Multiple adapters and accessories for compatibility with many lock types
USB-C cable, mounting hardware, extra fitting parts

I also received the SwitchBot Keypad Vision, which is the “star” accessory in this setup:

Professional, solid build
USB-C rechargeable battery
Facial recognition + keypad functionality
Includes everything needed for mounting on your door frame

Installation: Easy (With One Real-World Catch)

SwitchBot makes installation approachable, even if you’re not very technical. Insert the battery, follow the app steps, and the lock is operational quickly.

That said, I ran into a classic European-door reality check:

✅ The lock fit my cylinder
❌ But my key was too thick and too long

I ended up filing down the key head so the lock could mount correctly. I was worried I’d need to replace multiple locks in my house, but after some tinkering, it worked.

Important: If your door uses keys on both sides, make sure your lock supports unlocking from outside even when a key is inserted on the inside.

Door open/close detection is done with a small magnet on the door frame, which takes about a minute to install.

Keypad Vision Facial Recognition Test (Cardboard Ed Moment)

Once installed, it was time for the big test: facial recognition.

You can configure:

Sensitivity
Recognition distance (up to 3 meters)

And yes… I tested whether the lock could be fooled using a photo.
Result: It only unlocks when I’m physically standing in front of the door, and recognition is fast.

Other unlock methods:

PIN code
Fingerprint
NFC card
App unlock
Manual unlock from inside (knob or button)

There’s also a useful security option: you can disable the inside button, which matters if your lock is near a mail slot (where someone could potentially reach in).

Features and Options

The Lock Ultra includes several helpful options:

Auto-lock when the door closes (works flawlessly in my testing)
Adjustable rotation speed (3 levels)
Quiet mode that’s usable at night without waking anyone
Can be used like a doorbell feature… but there’s a catch:

Home Assistant limitation

Right now, I don’t see the doorbell trigger exposed in Home Assistant, meaning I can’t build my own HA automations around it. That’s a missed opportunity.

Home Assistant Integration (Cloud, Matter, or Bluetooth)

You can integrate the Lock Ultra in multiple ways:

SwitchBot Cloud integration (easy, but cloud-dependent)
Matter (requires a SwitchBot Hub — Hub 2 works, Hub Mini is included)
Bluetooth (for a more local approach)

It also works with:

Google Home
Amazon Alexa
Apple HomeKit (via hub)

SwitchBot Lock Ultra vs Aqara U200

Here’s where the SwitchBot Lock Ultra won me over:

What I liked more than the U200

Auto-lock reliability (my #1 reason for switching)
Smooth operation and consistent performance
Rechargeable Keypad Vision (no constant battery swapping)
Setup felt stable and “finished” from day one

What I still want improved

More Home Assistant sensors/triggers, especially doorbell events
More automation hooks for advanced features

Final Verdict

I’m a fan — and so are my kids. They love walking up and having the door unlock via facial recognition.

My wife? She still prefers using a key from the outside.
Luckily, that’s still possible.

If SwitchBot adds more Home Assistant-visible triggers (especially the doorbell), this could become one of the best smart lock setups for Home Assistant users.
