Summary

The Aqara U200 retrofit smart door lock (https://www.amazon.com/Aqara-Fingerprint-Included-Rechargeable-SmartThings/dp/B0D1C75J4F) offers fast, hub-free connectivity with all modern access methods. This is currently the most versatile lock with respect to physical installation - able to be installed on a variety of different kinds of doors/locks.

Breakdown

• Installation should take less than 5 minutes for most locks/doors.
• The lock comes in a variety of colors to match your home’s decor (white, silver, dark gray, and wood).
• Small profile relative to other retrofit smart locks on the market.
• Supports key cards, pin codes, proximity via NFC, proximity via Apple Homekey, and control via the Aqara app.
• Uses a gyroscope to detect door opened/closed status
• Includes “silent mode” to prevent lock/unlock motor from making too much noise
• No additional hub is required for most Aqara U200 functionality. However, the Aqara M3 Hub (https://www.amazon.com/Aqara-Automation-Controller-Bluetooth-SmartThings/dp/B0CWLHSKYC) is highly recommended to support all use cases (Airbnb, etc).
• Supports integration with Alexa (via Amazon Echo), Apple Homekit (via HomePod Mini), or Google Home (via Google Nest Hub).
