What happens when more than one gateway detects the same smart tag?

  • Updated

When you are using ON!Track, Smart tags may sometimes be detected by more than one gateway at the same time. This is normal behaviour and usually occurs when the tag is within the Bluetooth range of multiple gateways.

How detection works

Each Smart tag is assigned to a specific gateway. However, if the tag is physically close to another gateway, that gateway may also detect it.

For example: Smart Tag 1 is assigned to Gateway A. Because the tag is near Gateway B, Gateway B can also detect the same tag.

How This Appears in ON!Track

To ensure accurate tracking and transparency, ON!Track displays the tag differently in each gateway’s inventory:

 

 

The tag will appear in the two inventories as follows:

 

Gateway A - Smart tag 1 Expected and Found

 

Gateway B - Smart tag 1 Unexpected


This behaviour ensures that the assigned gateway remains the primary source of truth, while still providing visibility when a tag is detected by nearby gateways.

When a tag is detected by a gateway that is not assigned to the asset's current location, ON!Track may automatically transfer the asset to that location if all required conditions are met. If any condition is not met, the asset is added to the Suggested Transfers list instead.
 

Why an automated transfer may not happen

For an automatic transfer to work, the asset must be detected by only one gateway at a time. If the same asset is detected by two or more gateways at the same time, ON!Track cannot determine which location the asset should be transferred to. 
 
As a result, the automatic transfer is not performed.

Instead, the asset is added to the Suggested Transfers list for manual confirmation.

What you may notice

  • The asset stays in the Suggested Transfers list longer than expected.
  • An automatic transfer does not happen, even though the feature is enabled.
  • The asset may remain in the list after one of the gateways is no longer nearby.

What to do

  • Go to Alerts > Suggested Transfers.
  • Find the asset in the list.
  • Check the suggested destination.
  • Confirm the transfer manually.

Note: This most often happens during loading or unloading when two vans, or two locations with gateways, are parked close together. After the transfer is confirmed, the asset is moved to the correct location and removed from the list.line 2.png
