Aqara Smart Lock U200 (UK Kit) — Matter over Thread Retrofit
Matter-over-Thread retrofit lock for Euro, UK oval and Scandi cylinders. Fingerprint, NFC, PIN, Home Key, mechanical-key fallback.
3.9 / 5
★★★★★ ★★★★★ Recommended with caveats
Strengths
- Native Matter over Thread - pairs with Apple Home, Google Home, Alexa, SmartThings and Home Assistant without an Aqara hub
- Retrofit-from-inside design leaves the exterior of the door unchanged, helpful in rented and leasehold UK properties
- USB-C rechargeable Li-ion pack rated for around six months between charges, with an AA-battery adapter fallback
Watch outs
- Not compatible with traditional British five-lever mortice locks - fits Euro profile, UK oval and Scandi cylinders only
- Body is bulky (152.5 mm tall, 60 mm deep) and can foul handles or interior trim on outward-opening doors
- Reports of unit-to-unit variance - some owners receive locks that struggle to drive the cylinder consistently
£195.98
