?? Nuki: Smart Locks, Access Codes, and Unlocking APIs

?? Introduction

In recent years, the ?? home and business security sector has seen significant growth in the use of ??? smart locks. Among the many options available, Nuki stands out for its easy installation, flexible usage, and integration with various digital ecosystems.

This article will cover:

• ? What Nuki is and how it works.
• ? Managing access codes.
• ?? Unlocking APIs for automation.
• ??? Strategies to enhance security and access tracking.

?? What is Nuki and How Does It Work?

Nuki is a ?? smart lock system designed to be installed on existing locks without replacing them.

? Key Features of Nuki:

• ?? Automatic locking and unlocking via Bluetooth, Wi-Fi, or mobile app.
• ??? Smart Home integration (Alexa, Google Assistant, HomeKit, IFTTT).
• ?? Remote access management via the app and APIs.
• ? Real-time access logs to track entries.
• ?? PIN codes & biometric access via external keypads.

These features make Nuki a perfect solution for homes, offices, and rentals.

?? Access Codes: How Do They Work?

Nuki allows access management via custom PIN codes, which can be used with the Nuki Keypad.

?? Types of Supported Codes:

1. ?? Permanent Codes: No expiration, ideal for homeowners or full-time users.
2. ? Temporary Codes: Valid for specific time frames (guests, service personnel).
3. ?? One-Time Codes: Expire after a single use, great for one-time access.

??? Managing Codes via API

Nuki’s API allows you to create, update, and revoke access codes dynamically.

Example API request to create a new code:

PUT https://api.nuki.io/smartlock/auth
{
  "name": "Guest 1",
  "type": 13,
  "code": "123456",
  "smartlockIds": ["xxxxx"],
  "allowedFromDate": "2024-12-20T13:00:00.000Z",
  "allowedUntilDate": "2027-12-25T11:00:00.000Z",
  "allowedWeekDays": 127
}        

This request assigns the PIN code "123456", valid from December 20, 2024, to December 25, 2027.

?? Nuki API: Automation and Remote Control

The Nuki API allows you to automate and control smart locks via ? REST HTTP commands.

? Key API Features:

• ?? Remote unlocking & locking
• ?? User & permission management
• ?? Access log retrieval
• ??? Device configuration

Example API request to unlock a door:

curl -X POST "https://api.nuki.io/smartlock/xxxxx/action/unlock" \
     -H "Authorization: Bearer YOUR_API_TOKEN" \
     -H "Content-Type: application/json"        

This unlocks the door linked to the smart lock ID xxxxx.

Example API response:

{
  "success": true,
  "action": "unlock",
  "smartlockId": "xxxxx"
}        

??? Security and Access Tracking Strategies

?? 1. Custom API Tokens

Each API request requires a token. Using a single token for all operations reduces traceability. A better solution is to generate unique API tokens per user, ensuring that every access is logged.

?? 2. Regular PIN Rotation

To boost security, it’s advisable to:

• Use ? short-term codes that expire quickly.
• Set ?? one-time codes for temporary access.
• Assign unique codes for every user.

?? 3. Mobile App Authentication

To avoid PIN code misuse, a safer alternative is authentication via mobile app, reducing the risk of intercepted codes.

?? Conclusion

Nuki is a versatile and secure solution for access management. With its APIs, you can automate unlocking, manage PIN codes, and track entries in real time.

?? Key Takeaways:

• ?? Access codes can be permanent, temporary, or one-time use.
• ?? Nuki’s API enables automation & remote control.
• ??? Security measures like PIN rotation and user-based API tokens increase safety.

With proper implementation, Nuki enhances both convenience & security for homes, offices, and rentals.
