With features like remote locking via app, anti-peep passcodes, and easy DIY installation, it offers flexible access control that adapts to your lifestyle—whether you’re at home, away on vacation, or hosting guests.

Built for homeowners, renters, and property managers alike, the Yamiry Smart Knob eliminates the hassle of lost keys, forgotten duplicates, or unauthorized access. It provides full visibility and control over who enters your space and when, giving you confidence in your home’s security. The lock supports multiple user levels, time-limited codes, and instant notifications, making it an ideal solution for dynamic living situations. From streamlining tenant transitions to granting temporary access to delivery personnel or housekeepers, this smart lock enhances both safety and efficiency.

Key Features

• Unlock and Lock with App: Take full control of your door from anywhere using the dedicated mobile app. Simply connect to Wi-Fi and remotely lock or unlock your front door, ensuring you never have to worry about whether you left it open. This feature is especially useful when you’re running late, expecting deliveries, or want to grant access before arriving home.
• Grant Passcode Remotely: Share temporary or permanent access codes directly through the app—no need to hand over physical keys. Whether it’s a guest, cleaner, repair technician, or family member, you can instantly send a unique code that expires after a set time or after a single use. This eliminates the risk of lost keys and gives you precise control over who can enter and when.
• View Access Logs: Stay informed with detailed, real-time activity logs that record every entry. See exactly who accessed your door and at what time, which helps monitor household activity, track service visits, or investigate unusual access patterns. These logs are accessible through the app and can be reviewed at any time for added accountability.
• User Management: Assign different access levels and permissions to multiple users, making it simple to manage household members, roommates, or frequent visitors. You can create individual profiles, adjust privileges, and revoke access instantly if needed—ideal for shared living spaces or multi-family units.
• Rental Management: Simplify property management with built-in tools for tenant onboarding and offboarding. Generate time-limited passcodes that automatically expire, reducing the need for physical key exchanges. Landlords can monitor occupancy, grant access during move-in/move-out, and maintain security without constant coordination.
• Anti-Peep Passcode: Protect your privacy during code entry by adding random numbers before or after your actual password. This prevents shoulder surfing and shields your credentials from being observed, even in busy or public areas. The system recognizes only your true code while ignoring the surrounding digits, ensuring security without sacrificing convenience.
