The Geofencing section allows administrators to create, view, and manage virtual boundaries—called geofences—within the Trio platform. These fences help you monitor device movement, understand where devices are located, and build location-aware workflows across your organization.
Use this page to view all existing geofences, create new ones, and assign device groups for monitoring.
Geofencing overview
The Geofencing tab shows a list of all configured fences. If no fences exist yet, the page will display an empty state with an option to add your first geofence.
What this page includes
A searchable list of all geofences
Options to sort fences by name
Key details such as radius, assigned device groups, and in/out counts
Quick access to each fence’s map view
A button to Add fence
This page gives you a complete overview of how your geofencing environment is structured.
Geofence list view
When fences exist, they appear in a table format. Each row gives you a summary of the fence and its associated activity.
Displayed information
Fence ID/Name
Description
Radius
Device groups
Inside the fence (number of devices currently located inside)
Outside the fence
Map (quick link to open the fence in map view)
How to use
Search for a fence by name using the search bar.
Sort the list using the Name filter.
Select any fence to open its details page or “View map” for a visual preview.
This view is useful when managing large numbers of geofences across multiple locations.
Grid view
Trio also offers a card-style grid view for geofences, showing a visual preview of each fence on a map.
What the cards show
Fence name and description
A map preview with the radius drawn
Radius measurement
Assigned device groups
Total devices linked to the fence
Quick actions menu
This view is ideal for visually comparing location boundaries at a glance.
Map view
Selecting View map opens a dedicated map for the selected fence.
Here, you can view the exact positioning and radius of the fence, along with details about associated device groups and assignment status.
Information shown
Fence name and description
Exact address and coordinates
Device group count
Device count
Radius
Created by (user)
This view gives you a geographic context of the fence and helps verify correct placement.
Geofence details
Selecting a fence opens the Details page.
This page contains two tabs: Device group and History.
Device group tab
Shows all device groups linked to the geofence.
If none exist, you will see an empty state prompting you to assign groups.
History tab
(Your screenshots show this only as a tab placeholder; no content shown—but I can create content if you want.)
Assign device groups
Selecting Assign device group lets you assign the fence to specific device groups.
This determines which devices will be monitored for being inside or outside the fence.
Available controls
Search device groups
Sort by name
Filter by ownership or platform
View last updated timestamps
Assign multiple groups at once
Once assigned, devices in that group will appear in the “Inside” or “Outside” counts on the geofence list.
When to use geofencing
Use geofences when your organization needs to:
Monitor device movement across physical locations
Track entry and exit from offices, warehouses, or service areas
Understand where specific fleets are operating
Combine location activity with policies or alerts
Improve oversight for field teams or distributed workforces
Next steps
After setting up geofences, you can:
Review device locations in Last location
Track geofence transitions in Fencing history
Configure alerts for entry/exit events
Adjust fences or assign additional device groups
