## What is Jeff 2.0?

With Jeff 2.0 you get the possibility to receive telemetry data from the current F1 game. 

You can see the weather forecast for the current weekend much more accurately than in the game itself.

You can also view information about the times, battery status and reference status of your competitors in the ranking list. 

The live dashboard displays all data in a large and clear format so that you can keep an overview in the cockpit even during the session
