SmartAccess works seamlessly with a single SAM module and also supports installations with multiple modules. When several modules are installed near each other, the system automatically coordinates their behavior to ensure reliable and predictable operation.
When Are Modules Grouped?
SmartAccess automatically groups modules when their geofence areas would overlap by less than 100m. In this case, the modules share a common geofence and certain features are managed jointly.
If the distance between modules is greater, they operate independently.
Parallel vs Grouped Modules
| Scenario | Behavior |
|---|---|
| Parallel Modules | Modules operate independently. Geofence settings may be limited to prevent overlapping geofence areas. |
| Grouped Modules | Modules are automatically combined into a SmartAccess Group and share a common geofence. |
SmartAccess automatically selects the appropriate behavior based on the distance between modules.
Parallel Modules
In this scenario, multiple SmartAccess Modules are located near each other but remain far enough apart to operate independently.
To prevent overlapping geofence areas, SmartAccess may automatically limit certain geofence settings. These safeguards ensure reliable detection and prevent unintended triggers when multiple modules are nearby.
When modules operate in parallel:
- Each module uses its own geofence
- The geofence radius may be limited or fixed by the system
- Manual adjustment of the geofence radius may be restricted or disabled
This behavior is applied automatically when a geofence overlap of less than 100m can be avoided.
Limited Geofence Radius Adjustment
When another SmartAccess Module is nearby, SmartAccess limits the adjustable geofence radius to prevent overlapping geofence areas.
You can still adjust the geofence radius, but only within a restricted range (for example 400m instead of 500m).
Geofence Radius Fixed by System
When SmartAccess Modules are very close to each other, SmartAccess automatically sets the geofence radius to the minimum safe size (200m) to prevent overlap.
In this case, the geofence radius cannot be adjusted, and the control is hidden in the app.
Why Is the Geofence Radius Locked or Limited?
If the geofence radius slider is hidden or limited, another nearby SmartAccess Module has been detected.
To prevent overlapping detection areas, SmartAccess may automatically limit or lock the geofence radius. This ensures reliable detection and prevents unintended unlocking.
This safety limit cannot be overridden.
Grouped Modules
If SmartAccess Modules are installed very close to each other and a geofence overlap of less than 100 m cannot be avoided, SmartAccess automatically combines them into a SmartAccess Group.
In this setup, certain settings and behaviors are shared across all modules in the group.
- Shared geofence – All doors in the group use a single common geofence.
- Notifications – You receive one notification for the entire group instead of separate notifications for each door.
- Keyless features – KeylessGo and AutoUnlock should be enabled for only one door within the group.
This automatic grouping ensures predictable behavior and prevents devices from switching between nearby geofences.
Shared Geofence
The geofence areas of all doors in the SmartAccess Group are combined into a single shared geofence.
The size of this shared geofence is automatically determined by the system to ensure reliable detection and cannot be edited.
Notifications
When entering the shared geofence of a SmartAccess Group, you receive one group notification instead of multiple notifications for each door.
If geofence notifications are enabled or disabled for one module, the setting automatically applies to all modules in the SmartAccess Group.
KeylessGo & AutoUnlock
Use KeylessGo or AutoUnlock for only one door within a SmartAccess Group.
For security reasons, keyless entry is limited to a single door per group. Once KeylessGo or AutoUnlock unlocks one door, keyless entry for the other doors in the group is cancelled.
To keep control over which door unlocks automatically, enable KeylessGo or AutoUnlock on only one door in the SmartAccess Group.
Note: Unsupported Configurations
The following configurations are currently not supported and may not work as expected.
Time-Limited Access Profiles
Using keyless features in a SmartAccess Group together with time-limited access profiles (for example, a cleaner with access only on specific days) is not supported.
Generic Locks (Without Door Status)
For reliable multi-module safety logic, SmartAccess requires door status information (open/closed). Generic locks without door status feedback cannot provide the same level of protection against conflicting signals in multi-user environments.
