Receiving telematics messages from hundreds of GPS tracker types by multiple manufacturers and
giving them to you in an easily manageable format is the primary goal of the flespi telematics
hub. What PVM does is unscrambles each message according to the protocol specification, applies
universal parameter naming, and saves the message in a JSON format.
The common naming scheme enables aggregate data processing across protocols, while the
ubiquitous JSON format makes it straightforward to access the data from any target application.
The same is true for the opposite direction - you can send commands to devices and they will
automatically convert into the proper format for the receiving device.
