How to create a VW TP2.0 sensor to read VW TP2.0 parameters:
You need to know 3 elements: unit, group number, number of the desired parameter in the group (from 1 to 4).
In the sensor editor (Settings – Sensors – Create new (+) or click on an existing custom one):
1) Choose Decode scheme: VW TP2.0 Group Item.
2) Fill 6 fields: Name, Shor name, Unit, Group, Item (1-4) and Units.
3) And tap “Apply“.
App would fill other fields automatically.
Example: DSG DQ200 fluid temperature: unit 02, group 11, item 1.
