The Device Health app in Trackunit Manager helps you monitor and troubleshoot device connectivity issues.
It gives you visibility into your devices’ health, highlights connectivity problems, and recommends actions to resolve them.
Navigating Device Health

When you open the app, you’ll see the following tabs:
Overview: Shows how well your assets are connected and highlights devices that need attention
Devices: Lists all devices with their key data and filter options
Data Feeds: Shows the data feeds currently connected to your account
