Trip tracking, charging costs and service reminders for Tesla

Everything your car does, with the cost next to it.

A tour of Viametry, from the daily overview to the logbook your accountant receives.

Overview

A calm start to every day.

See where your car is, how much range it has and what needs your attention soon.

  • Inspection, insurance and tyre reminders
  • Unusual battery, charging or tyre readings
  • Everything else stays out of the way

Trips

Every drive, grouped into trips.

Single drives become trips with their distance, energy and cost, ready to name, classify and export.

  • Round trips grouped automatically
  • Cost per trip and per kilometre
  • Export to CSV or Excel

Charging

Know what every kWh cost.

Superchargers come with Tesla's bill and home charging is priced from your tariff. A public charger gets its price once you save one for that place or enter the amount from your bill; until then it is listed as still to price.

  • Home, public and Supercharger side by side
  • Your home tariff, including night rates
  • Monthly trend of energy and cost

Metrics

Your driving, in patterns.

When you drive, what the cold costs and where your energy comes from. Insights, not scores.

  • Rhythm by weekday and hour
  • Efficiency by temperature and speed
  • Your year at a glance

Petrol comparison

What the same driving would have cost.

Choose a comparable petrol car and Viametry prices your kilometres at each week's pump price for your country.

  • 59 reference cars
  • Weekly prices from the European Commission
  • Your real charging bills, not estimates

Logbook

A logbook your accountant can work with.

For business cars: every drive with its purpose, driver and classification, checked against your country's rules.

  • Business and private kept apart
  • Six country profiles
  • Change history in every export

How it works in practice

From drive to trip

Once the virtual key is on the car, your Tesla sends its live data while you drive. Viametry turns each drive into a record with start, destination, distance, energy and time, and joins drives into trips: out to a client and back home becomes one round trip.

A sleeping or offline car sends its data later, so a drive can appear a few minutes after you park.

A worked example

Say your charging over the past weeks cost on average €0.21 for each kWh the car used, charging losses included. A 62 km round trip that used 11.4 kWh then cost €2.39, about €0.04 per kilometre.

Charge more at home on a night tariff and the average falls; the next trips show it. The cost always comes from what your charging actually cost, not from a fixed price.

Where the charging prices come from

  • Supercharger: Tesla's own bill, read from your charging history.
  • Home: the energy the car took in, priced with your tariff, night rates included. You enter the tariff once.
  • Public chargers: the price you save for that place (once, then automatic there) or the amount from the receipt. Until then the charge is listed as still to price.
  • A charge far above your usual price per kWh is flagged, so a wrong price stands out.

What you still do

  • Add the virtual key once, next to the car (about a minute).
  • Enter your home tariff, and a price for the public chargers you use.
  • Enter the dates for inspection, insurance and tyres you want to be reminded of.

Limits

  • Viametry only reads. It cannot unlock, start, drive or change anything in the car.
  • Drives, trips and maps need the virtual key. Some older cars cannot send live data to apps; charging, battery and software information still work there.
  • Works with Tesla Model 3, Model Y, Model S and Model X.
  • The petrol comparison is a comparison at weekly pump prices, not a bill.
