OwnTracks App Integration (for iOS only)
The Additional Marker and Remove Marker features are specifically designed for use with the OwnTracks app on iOS.
How It Works
In the example above:
- When marker
2200d7520007is detected, the system will:- Automatically add activity marker:
2200d7570301 - Automatically remove activity marker:
2200d152004a
- Automatically add activity marker:
A Community Alias is required for this functionality to work correctly.
This setup is especially useful in commercial buildings, where multiple Activity Markers may be installed to provide more accurate indoor location tracking.
For example, OwnTracks can manage multiple Activity Markers to reflect the user’s movement between floors:
- As the user approaches the building, the Ground Floor Activity Marker is automatically inserted.
- Once the Ground Floor Activity Marker is detected, the system adds the First Floor Activity Marker.
- When the First Floor Activity Marker is detected, the Ground Floor Activity Marker is removed to ensure the location display reflects the user’s current position accurately.
This allows dynamic marker management based on user location or proximity events, enhancing automation in field deployments or community setups.

- You will be prompted to choose an SMS notification setting:
- Press 1 to enable SMS notifications
- Press 9 to disable SMS notifications
Your marker will then be successfully linked to the mobile number with your selected SMS preference.
QR Code
Clicking the QR Code button will display the QR Code associated with the generated Activity Marker.
This QR Code can be:
- Scanned to trigger or detect the marker
- Shared with others for quick access or logging
- Printed for physical placement at a location
The URL generated for each marker can be used to program NFC tags.
In the example above, the URL is: https://88.io/2200d7520007
This URL represents the Public Marker and can be embedded into any compatible NFC tag.
When the Public Marker is scanned via:
- NFC tag
- QR code
- Direct URL
a location pin for that marker will be placed on: https://control.aunsw.88.io
This provides real-time visibility and logging of the scan event.
