Tesla Fleet Driver Monitoring: Alerts Across Every Tesla You Own

If you own more than one Tesla, Tesla fleet driver monitoring in the everyday sense means one thing: seeing how each of your cars is driven when it isn’t you at the wheel — with timely alerts across every vehicle on your account. Instead of waiting for a scratch to appear or an insurance letter to arrive, you get an alert when a car speeds, brakes hard, or goes out after hours. It connects through Tesla’s official Fleet API, so there’s nothing for the people driving your cars to install and no dongle to plug in.

Sentry Driver gives you that visibility without touching how the car drives. It is a monitoring and alerting tool — it never caps speed, limits acceleration, or restricts the vehicle in any way. You get the information; the driver keeps driving.

Why Owners of Several Teslas Want Visibility

When a car is yours but someone else is behind the wheel — a family member, a friend, a renter on a car-sharing platform, a valet — accountability gets blurry. A speeding ticket, a hard-braking near-miss, or a late-night trip can sit invisible for weeks until paperwork catches up. By then the chance to talk about it, or to document what happened, is gone.

Real-time visibility changes that in three ways:

• Safety - You know about risky driving while it’s happening, not only after an incident.
• Accountability - Trip history shows how a given car was driven, so there’s a clearer record if a rental or loan is disputed.
• Protecting your cars - Knowing how your vehicles are used lets you act on problems early, whether that’s a conversation or a decision not to lend again.

The goal is visibility, not control. Sentry Driver shows you what’s going on so you can have a better conversation about safe driving — it doesn’t take the decision out of the driver’s hands.

What You Get Alerted To

Sentry Driver watches the data Tesla streams from each car and turns it into timely alerts for the things that matter:

• Speeding - An alert when a driver exceeds your set threshold.
• Hard braking - A signal of aggressive or distracted driving.
• Accidents - Timely notification if Sentry Driver detects a possible collision or impact.
• Curfew / after-hours use - Know when a car is driven late at night or outside the hours you agreed.
• Geofence / zone violations - Get alerted when a car leaves an area it should stay in, or enters one it shouldn’t.

On top of the live alerts, you get weekly driving summaries for each vehicle, so patterns across your cars are easy to spot over time. For more on this use case, see our multiple Teslas and company car pages.

Monitoring Multiple Cars from One App

Sentry Driver supports multiple vehicles, so all your supported Model 3, Y, S, X, and Cybertruck vehicles can live in one app. Add each car once through Tesla’s Fleet API and you manage them all from a single account.

Owner detection is what makes this work cleanly. Sentry Driver uses Bluetooth to recognize when your phone is present in a car. When your phone is not detected during a monitored drive — for example, a renter picking up one of your cars — monitoring kicks in automatically and the alerts flow to you. There’s no key handoff, no profile to switch, and nothing for the driver to do.

No Hardware, Nothing for Drivers to Install

Most vehicle-tracking tools ask you to plug an OBD-II dongle into every vehicle. Teslas don’t expose a standard OBD-II port, so those trackers need an adapter to work at all — and someone has to physically install one in each car. Phone-based trackers have the opposite problem: every driver has to install and carry an app, and the moment they leave the phone behind, you’re blind.

Sentry Driver skips both. Because it reads directly from Tesla’s official Fleet API over a secure OAuth connection, there is:

• No hardware - nothing to buy, ship, or fit to each car.
• Nothing for drivers to install - the app lives only on your phone.
• No stored Tesla password - you connect through Tesla’s own login; we never see or keep your password, only the access token Tesla issues.

That makes adding a new vehicle a two-minute job rather than a garage appointment.

Tell the people who drive your cars

Let anyone who drives your car know it’s monitored — our terms require it. Being upfront keeps the focus where it belongs: on safety and on looking after your cars, not surveillance. Sentry Driver is sold to individuals for their own vehicles; if a car belongs to an employer, you need their authorisation and are responsible for the laws that apply. (This isn’t legal advice.)
