Diagnostics Hub.
A targeted add-on for mixed fleets — deployed only on the vehicles that benefit from it.

Deeper engine data on the vehicles where the standard connection doesn't tell the whole story.
The Diagnostics Hub expands what the Samsara Vehicle Gateway can read from the vehicle, capturing additional diagnostics for specific makes, models, and years. It connects to the Vehicle Gateway and adds support for further diagnostic protocols along with additional USB and auxiliary input capacity. Vidmatics confirms compatibility against your vehicle list before anything is ordered, so you only deploy it where it adds data.
