dashboard

Live telemetry dashboard for the Voltaris electric vehicle, reading the vehicle bus over UART on a Raspberry Pi.

---

What this does

Reads the vehicle telemetry stream over the Raspberry Pi UART and serves a live web dashboard. Built with Dash, Plotly and Bootstrap components.

Four channels are tracked and plotted, each on a rolling window of the last 100 samples:

Channel	Meaning
battery_voltage	Pack voltage
battery_soc	State of charge
motor_temp	Motor temperature
power_consumption	Instantaneous power draw

A background thread owns the serial port and pushes into thread-safe deques, so a slow browser never stalls the reader.

Wiring

The defaults in dashboard.py are the Raspberry Pi hardware UART:

SERIAL_PORT = '/dev/ttyAMA0'
BAUD_RATE   = 115200
MAX_POINTS  = 100

Change SERIAL_PORT if you are on a USB adapter — that is usually /dev/ttyUSB0 on Linux or a COM port on Windows.

Running

pip install -r requirements.txt
python dashboard.py

Then open the address Dash prints, by default http://127.0.0.1:8050.

adc_plot.py is a smaller companion script for looking at raw ADC values without the dashboard around them, which is the faster way to tell whether a sensor or the parser is at fault.

Part of

The Voltaris electric vehicle project. The unit that produces this telemetry is in AKS.
