Common questions
How do I connect my car?
Tap Connect in the app. You will be taken to the car maker's official page to sign in and approve access. Gemwatt never sees your password.
My data looks out of date.
To keep costs and battery use low, Gemwatt refreshes live data every few seconds only while the app is open, and history less often. If your car is asleep, the latest reading may be shown until it wakes. Pull down to refresh.
Why is battery health an estimate?
It is calculated from your charging sessions, not measured directly, so it can differ from other sources and gets more reliable with more data.
How do I disconnect?
In the app: More → Settings → Disconnect. You can also remove access from your car maker account. To erase your data, see Delete your account and data.
Which vehicles work?
Vehicles that offer data access through the manufacturer's official partner programme. The list of supported models and regions will be published before launch.
