Overview
Controlling a front door from an app, a keypad or a key is the job of this zinc deadbolt. It connects over Wi-Fi and Bluetooth, supports auto lock and auto unlock, and ships with a door sensor.
A direct network link removes the need for a separate hub, and the door sensor reports whether the door is open or shut. The limitation is that the listing gives no keypad code count, no door thickness range and no battery life.
Who it's for
Apartments, rentals and home offices that want remote access suit this lock. Anyone with a non-standard door should check the fit first.
Pros and cons
- Door sensor included
- Auto-lock and auto unlock
- Keypad and key backup
- Works with Alexa and Google
- Door thickness range not listed
- Battery life absent
- Code capacity not stated
- Zinc body only
Performance notes
The lock talks to the app over Bluetooth for near control and over Wi-Fi for remote control. Auto-lock re-secures the door after a delay and the sensor reports its position. Battery life and code count are not listed.
