Viametry

Viametry is a trip logbook and running-costs app for Tesla Model 3, Model Y, Model S and Model X, used by private owners and by companies with drivers in Europe. It reads the data the car already records, through Tesla's official interface, with read-only access to the car.

With this connector, Claude can:

• Answer questions about your trips, charging sessions and costs, such as what charging cost last month or how many kilometres you drove for business.
• Summarise a month: distance by business and private use, energy used, and charging cost by kind of charger.
• Check a business car's logbook for gaps: drives not yet marked business or private, business trips without a purpose, missing starts or ends, and the checks your country's tax office asks for.
• Do the paperwork, if you allow it: mark trips business or private, fill in purposes, notes, drivers and cost centres, add charging costs and prices, name places, and add expenses and service records.

You decide what Claude may do. When you connect, Viametry asks which cars Claude may see and whether it may only read or also make changes. Claude can never sign off the logbook, lock trips, approve or pay expenses, delete anything or change settings, and filed trips cannot be changed. It never sees a VIN or exact coordinates. Every request is listed in the account history, and you can withdraw access in Viametry at any time.

You need a Viametry account with a car connected. Logbook tools are for business cars.
