1. What is TeslaFi?
TeslaFi is a web-based analytics tool that connects to your Tesla via the official API to log, track, and visualise everything your car does, from charging sessions and energy efficiency to trip history and software updates.
2. Is TeslaFi safe?
Yes, TeslaFi uses the official Tesla API and your login is never shared directly. You generate a secure token to connect your car, the same way many other apps do.
3. Does TeslaFi work in the UK?
Absolutely. TeslaFi works with UK Tesla accounts, vehicles, chargers and energy tariffs. It’s particularly useful for mileage tracking, home charging logs, and tax reporting.

TeslaFi records:
- Trips and driving behaviour
- Charging sessions and locations
- Battery health and degradation
- Software updates
- Temperature impact on efficiency
- Sleep and idle state losses
5. Can TeslaFi damage my Tesla?
No. It reads data via Tesla’s own secure API and cannot send dangerous commands or damage the vehicle in any way.
6. How does TeslaFi compare to the official app?
TeslaFi offers:
- Historical data and exportable reports
- Custom tagging and filtering of trips

The official app is great for real-time controls, but lacks history, graphs, or long-term tracking.

Why I Prioritize Deeper Tesla Analytics
Owning a Tesla day to day taught me quickly that the default app is good for core controls but limited for historical analysis. Once you start doing regular long trips and home charging planning, deeper data becomes genuinely useful for spotting trends and improving decisions. In my case, that includes watching charging behaviour, efficiency changes, and practical patterns that affect real running costs. That ownership reality is why this TeslaFi FAQ exists in plain language. It is designed to answer the exact questions drivers ask when deciding whether a dedicated analytics tool is worth adding on top of the standard Tesla experience.
