Smart locks for properties with unreliable WiFi
Last updated: December 11, 2025
Use case
You manage short-term rental properties where WiFi connectivity is unreliable or frequently goes down. You need smart locks that can continue functioning and allowing guest access even when the local WiFi network is unavailable.
Challenge
Most smart locks rely on WiFi connectivity to communicate with cloud services and receive access codes. When WiFi goes down, these locks may lose the ability to receive new codes, update existing codes, send notifications, or respond to remote commands.
Recommended solutions
Option 1: Salto KS with cellular connectivity
Best for: Properties where you need real-time remote code management even when WiFi is down
Key benefits
Independent of local WiFi - Communicates directly with Salto's cloud services via cellular networks (4G/LTE)
Continuous operation - Receive new codes, process updates, report activity, and respond to remote commands even during WiFi outages
Reduced support burden - No need to troubleshoot WiFi issues or coordinate with ISPs
Reliable for remote properties - Works in rural areas or locations with inconsistent internet service
Considerations
Requires adequate cellular signal strength at the property
Higher upfront cost and cellular subscription fee
Slightly faster battery drain compared to WiFi-only models
Option 2: Offline-capable locks (Igloohome, Lockly)
Best for: Properties where codes can be generated in advance and don't need to be modified after creation
Key benefits
No internet dependency - Access codes work regardless of network status
Generate codes anytime - Create codes even when property WiFi is down
Lower cost - No cellular subscription fees or additional hardware required
Works anywhere - Perfect for remote properties with no reliable WiFi or cellular coverage
Considerations
Codes cannot be changed - Once generated, codes cannot be modified or revoked remotely
Limited real-time monitoring - Activity logs sync when connectivity is restored
No remote firmware updates or setting changes during WiFi outages
