OLUMAT B28 Smart Lock with Handle
This smart lock is for the homeowner who juggles family schedules and occasional guests. It's perfect for letting in a dog walker while you're at work or granting access to a visiting relative without sharing a physical key.
While many focus on home security, this lock offers true convenience for daily life. You can create a one-time code for a contractor that expires after they leave, ensuring no lingering access. The fingerprint scanner works reliably even with wet hands from groceries, letting you in without fumbling.
Installation is straightforward with a screwdriver, fitting most standard U.S. doors. Pair it with the optional Wi-Fi gateway for remote control via the app, making it an Alexa compatible smart lock for hands-free management. You get real-time logs and peace of mind without ongoing fees.
Features
- Remote control via Wi-Fi gateway for lock/unlock, code setup, and access logs
- Easy installation in minutes with a Philips screwdriver, no drilling or wiring
- Ideal for homeowners and rental hosts like Airbnb, with remote passcode generation
- Free app use forever, 30-day money-back guarantee, 1-year warranty, lifetime support
