List of Supported Vehicle State Capabilities⚓︎

The table below shows you the complete list of vehicle state capabilities currently supported by the INVERS OneAPI. We are constantly adding additional capabilities as telematics units and their protocols or APIs become more mature and add new features.


You can find more details about data types and value ranges of each vehicle state property in our API reference (e.g., response of “latest vehicle state”).

Please note that each of the vehicles in your OneAPI fleet has its own list of supported vehicle state capabilities, which usually is a subset of the complete list you can find here. This is due to the different form-factors and vehicle types, but also varies depending on the telematics unit built into the vehicle. Even when using the same telematics unit in all of your vehicles, the capabilities can vary from one vehicle to another based on differences in the vehicle brand and model.
