As the Matter standard continues to mature, smart locks are becoming one of the most discussed device categories. Among different deployment options, Matter over Wi-Fi smart locks remain a practical and widely adopted solution for many projects.
This guide explains what Matter over Wi-Fi smart locks are, how they work, where they fit best, and how they compare to other Matter networking options in real projects.
What Is a Matter over Wi-Fi Smart Lock?
-
Uses Matter as the application protocol
-
Uses Wi-Fi as the underlying network layer
In simple terms:
-
Matter defines how the lock communicates and behaves
-
Wi-Fi defines how the data is transmitted
The smart lock connects directly to an existing Wi-Fi network, without using a Thread mesh or Border Router.
Understanding Matter’s Role in Wi-Fi Smart Locks
Matter itself is not a wireless protocol. It is an IP-based interoperability standard designed to unify smart home devices.
When Matter runs over Wi-Fi:
-
The lock receives a direct IP address
-
Communication uses standard IP networking
-
Devices can interact locally and across ecosystems
This makes Matter over Wi-Fi a familiar and accessible architecture for many installers and system integrators.
How Matter over Wi-Fi Smart Locks Work
A typical Matter over Wi-Fi smart lock system includes:
-
A Wi-Fi–enabled smart lock
-
A standard home or building Wi-Fi router
-
One or more Matter controllers (apps, hubs, or platforms)
Communication Flow
-
The smart lock connects to the Wi-Fi router
-
Matter commands are sent over the local IP network
-
Optional cloud services enable remote access
Because Wi-Fi is already widely deployed, this setup often requires no additional hardware.
Key Advantages of Matter over Wi-Fi Smart Locks
-
Simple Deployment
Wi-Fi networks already exist in most homes and buildings.
This reduces installation time and complexity.
For many projects:
-
No mesh planning is required
-
No Thread Border Router is needed
-
Setup is familiar to installers
-
Direct IP Connectivity
Wi-Fi provides direct IP access.
This allows:
-
High bandwidth communication
-
Faster firmware updates
-
Easy diagnostics and monitoring
This is especially useful during development, testing, and maintenance.
-
Strong Compatibility with Existing Infrastructure
Many buildings already rely on Wi-Fi for:
-
Cameras
-
Intercoms
-
Access control systems
-
Building management platforms
Matter over Wi-Fi smart locks integrate naturally into these environments.
Limitations of Matter over Wi-Fi for Smart Locks
While Wi-Fi is convenient, it also has trade-offs—especially for smart locks.
-
Higher Power Consumption
Wi-Fi typically consumes more power than low-energy networks.
For battery-powered smart locks, this can result in:
-
Shorter battery life
-
More frequent battery replacement
-
Higher long-term maintenance cost
-
Network Congestion Risks
Wi-Fi networks often carry many devices:
-
Phones
-
TVs
-
Cameras
-
Laptops
-
Guests
In busy environments, this may affect:
-
Response time
-
Stability during peak usage
-
Reliability in large deployments
-
Router Dependency
Wi-Fi smart locks rely heavily on router quality and placement.
Poor router configuration can cause:
-
Signal loss
-
Intermittent connectivity
-
Reduced user experience
Matter over Wi-Fi vs Matter over Thread (Brief Overview)
While both options support Matter, their design goals differ.
-
Matter over Wi-Fi prioritizes ease of deployment
-
Matter over Thread prioritizes low power and long-term stability
For battery-powered smart locks, Thread is often preferred.
For fast deployment and powered environments, Wi-Fi remains a valid choice.
Best Use Cases for Matter over Wi-Fi Smart Locks
Matter over Wi-Fi smart locks are well-suited for:
Residential Homes
-
Strong Wi-Fi coverage
-
Moderate daily usage
-
Preference for a simple setup
Apartments and Rental Properties
-
Centralized Wi-Fi infrastructure
-
Easier onboarding for tenants
-
Reduced hardware complexity
Commercial and Office Buildings
-
Stable power availability
-
Existing network management teams
-
Integration with other IP-based systems
Prototyping and Early-Stage Products
-
Faster development cycles
-
Easier debugging
-
Simple certification paths
Security Considerations
Matter enforces strong security regardless of network type.
Matter over Wi-Fi smart locks use:
-
Secure device commissioning
-
Encrypted communication
-
Authentication and authorization mechanisms
However, network-level security still depends on:
-
Router configuration
-
Wi-Fi password management
-
Network segmentation practices
OEM and Manufacturing Perspective
From an OEM standpoint, Matter over Wi-Fi smart locks offer:
Advantages
-
Faster product development
-
Easier testing and certification
-
Lower entry barrier for new products
Challenges
-
Power optimization requirements
-
Battery performance expectations
-
Long-term maintenance planning
Manufacturers like YonAnn typically offer Matter over Wi-Fi as one option within a broader Matter product strategy, allowing customers to choose based on project needs.
Is Matter over Wi-Fi Future-Proof?
Matter over Wi-Fi will continue to exist and evolve.
It benefits from:
-
Global Wi-Fi availability
-
Mature hardware ecosystem
-
Ongoing Matter updates
However, for battery-powered smart locks, the industry trend is gradually moving toward lower-power Matter networking options.
In future projects, Wi-Fi and Thread are likely to co-exist, rather than replace each other.
Conclusion
Matter over Wi-Fi smart locks offer:
-
Simple deployment
-
Strong compatibility
-
Direct IP connectivity
They are best suited for:
-
Powered environments
-
Projects with existing Wi-Fi infrastructure
-
Fast deployment requirements
For battery-critical and long-term smart lock projects, other Matter networking options may offer advantages. But Matter over Wi-Fi remains a practical and important part of the Matter ecosystem in 2026 and beyond.
