Teslita
Free of charge

Every trip. Every home-charging kWh. Signed, exportable, audit-ready.

Teslita turns your car's own telemetry into the two documents your accountant actually asks for — automatically, continuously, with a signature any reviewer can verify.

Ready in two minutes No dongle or extra app Cryptographically signed

Two documents. Continuously generated.

You don't build them. You don't remember to update them. The car does it.

Home-charging statement

Get reimbursed for the electricity your car uses at home

Every kWh your Tesla takes at home — date, time, duration, energy added, and derived cost. Location verified by GPS at the moment of charging, so the statement proves the electricity went into this car at this address.

  • Per-session detail, not rounded monthly totals
  • Cost derived from your actual kWh price
  • Signed PDF export with hash-chained audit trail

Driving log

A trip log that writes itself

Teslita captures every trip your Tesla makes from the car's own gear, GPS and odometer signals. Start and end address, route, kilometres, timestamp — automatic. You classify each trip as business, private or commute with one tap.

  • Every trip, no forgotten entries
  • Continuous odometer chain — no gaps
  • Signed monthly export with a verifiable PDF signature

Built to survive a review

A log is only useful if whoever reviews it trusts it. Teslita is designed so your accountant, employer or tax auditor can verify the document on their own.

Hash-chained edit log

Every change to a trip or charging session is linked by cryptographic hash to the one before it. A tampered entry breaks the chain.

Signed PDF exports

Every report is signed with an X.509 certificate. Verifiable in any standard PDF reader — no special software required.

Immutable source data

The car streams raw odometer, GPS and gear signals as events. Reports are rebuilt from those events, not from editable totals.

Common questions

Will my accountant accept this?
The exported PDF contains the four data points any mileage-logbook standard expects: date, start/end address, odometer, classification. Signed so your accountant can verify in any PDF reader that nothing has been altered.
Why is Teslita free?
Side project, low server costs, no paid tier, no ads, no data resale. If that ever changes, you hear about it first — and any account is fully exportable at any time.
Do I need to install anything?
No dongle, no OBD adapter, no app. Teslita uses Tesla's official Fleet Telemetry; you approve a virtual key in the Tesla app once.
Can I export if I stop using Teslita?
Yes — full JSON bundle plus all PDF reports. No lock-in.
Is Teslita affiliated with Tesla?
No — independent service using Tesla's official Fleet Telemetry API with your authorisation.
