The sensor display has been split into four areas representing each tyre; front left tyre (top left), front right tyre (top right), rear left tyre (bottom left), and rear right tyre (bottom right).
For each tyre, available information includes a visual heat block temperature representation, live temperature, and maximum temperature achieved.
You will also see the current vehicle speed and the VMAX speed displayed in the middle of the sensor display.
The VMAX value is saved and will be displayed again next time the unit is powered on. Reset the VMAX value to the current speed value by tapping the Reset button in the footer.
Each sensor measures 16 temperature points across the tyre surface, displayed as heat blocks on the main screen.
The heat blocks change colour based on temperature, blending between blue, green, yellow, and red, where blue represents the lowest temperatures and red represents the highest temperatures.
If the heat blocks appear greyed out, VBOX Touch is not detecting a CAN connection.
You can see a live temperature value in numerical form for each sensor displayed on the Sensor Display. Each displayed temperature value is an average of the 4 most central temperature channels for that particular sensor.
If the sensor does not receive a temperature reading, '--' will be displayed.
The app will store the highest measured temperature from each sensor and display them on the Sensor Display.
Until the app receives a temperature reading, you will see "--" displayed in its place.
The app will remember the max temperature values after a power cycle, but you can reset them by tapping the Reset button in the footer of the Sensor Display.
NOTE
Maximum temperature values are displayed in grey to distinguish them from live readings.

The four LEDs at the top of the unit provide visual feedback based on the current operation of the VBOX Touch
The LEDs are mapped to the sensors and indicate if one or more tyres are overheating.
Each LED corresponds to a tyre position: RL (rear left), FL (front left), FR (front right), and RR (rear right).
If any temperature sensor records a value above the configured Overheat Temperature (set in the Temperature Settings), the corresponding LED illuminates red.
The LED remains red until the temperature on that tyre has stayed below the overheat threshold for at least 1 second.

The Tyre Temperature App provides a real-time visual overview of tyre temperature data from the connected Tyre Temperature Sensors.
During operation, use the heat blocks to monitor temperature distribution across each tyre. The colour range from blue (cool) to red (hot) allows you to quickly identify uneven heating or potential overheat conditions.
The LED indicators provide immediate visual feedback for key events, such as overheat warnings and screenshot captures.
Ensure that the displayed sensor positions (FL, FR, RL, RR) match the physical installation on the vehicle, as incorrect configuration may result in misleading data.
The satellite icon indicates GNSS status and should show a valid lock before relying on logged data or time synchronisation.
The Tyre Temperature App logs a standard .vbo data file containing all standard GPS parameters, along with 16 CAN parameters from each sensor (64 in total).
