Every Tesla you own.
One live dashboard.
WattLoft streams your car second by second — battery, charging, climate, location, the lot — and keeps every drive, every charge and your battery's real health, forever. Create an account, connect your Tesla, and it's everywhere you are: web, iPhone, Mac, Apple Watch and Homey.
Free during early access · works with every Tesla · nothing to install
Everything the car knows, kept.
Tesla's app shows you the moment; WattLoft keeps the history and does something with it.
Live telemetry
The car streams straight to your dashboard — battery, temperatures, tire pressures, location — second by second, over 150 fields deep.
Drives & charges
Every trip with its route on a map, every charging session with cost and energy — searchable, forever.
Battery health
Pack capacity measured from your actual charging, tracked over time — not a guess from rated range.
Automations
Rules that watch while you don't: precondition at 7:30, stop charging at a price cap, lock up when everyone leaves.
Alerts
A door left open, a charge interrupted, the car gone offline — a notification the moment it matters.
Accounts & sharing
Give the family their own logins, share a read-only live page with anyone, and keep admin things admin-only.
Native apps.
The same dashboard in your dock and your pocket — widgets, notifications and all.

No hardware, no setup, nothing to install — your account is the whole installation.
Create your account
One email, one password, and your dashboard exists — at connect.wattloft.com, ready for its first car.
Connect your Tesla
You sign in on Tesla's own page and approve the virtual key from the guided setup. WattLoft never sees your Tesla password.
Just drive
History accumulates by itself. Come back to graphs, costs, battery trends and a searchable log of everything — on any of your devices.
Your car's data works for you — and nobody else. WattLoft talks straight to Tesla and keeps your history in your account, full stop. No analytics trackers, no data brokers, no reselling, no third parties between you and your car — and if you leave, your data goes with you.
Built properly.
The parts you don't see, done the way you'd want them done.
Streams, not polls
Cars on Tesla's Fleet Telemetry push data the moment it changes — your dashboard moves with the car, second by second.
Gentle on the car
Nothing ever wakes your Tesla just to read it — a sleeping car stays asleep, so WattLoft never causes vampire drain.
Tesla's own front door
Sign-in happens on Tesla's page, commands travel Tesla's signed command protocol. Your Tesla password is never seen, never stored.
Real battery science
Capacity measured from your actual charging sessions against a database of every pack Tesla ever shipped — not a guess from range.
Everything encrypted
TLS on every connection, mutual TLS from the cars, sign-ins locked down against brute force.
Yours to share
Family logins, view-only or full-control shares, live links for anyone — you decide who sees which car.

Can I try it before connecting my car?
Is my Tesla password stored anywhere?
Will it drain my battery?
Can my family use it too?
Can I delete my data?
