NineWatt works with the OBDLink MX+. First pair it with the phone itself:

• Plug the MX+ into the car's OBD-II port and switch the car on.
• Press the button on the MX+, then pair it in your phone's Settings → Bluetooth.
• Open NineWatt, go to the Adapter screen (in More) and choose the MX+.

If it still won't connect, close any other OBD app that may be holding the connection, switch Bluetooth off and on, and unplug the adapter for ten seconds.

The battery management system answers only while the car is on (ready to drive) or charging. If values still don't appear, send us a session log (More → Session log → export) and we'll look.

Yes: on the Adapter screen, choose the built-in IONIQ 9 simulator. It behaves like the adapter and the car, with made-up data.

A few minutes after the high-voltage system switches off, NineWatt stops asking the car for data and only checks the 12 V battery every ten minutes, so the car can go to sleep. The adapter itself still uses a little power while plugged in; unplug it if the car will sit for a long time.

Open NineWatt Pro in the app and tap Restore Purchases, with the phone online. Make sure you're signed in to the same Apple ID or Google account you bought with. If it still doesn't unlock, write to us with the platform and the date of purchase. Please don't send payment card details.

Install NineWatt there, sign in to the same Apple ID or Google account, and use Restore Purchases. Your devices share the same votes.

• iPhone: Settings → your name → Subscriptions → NineWatt, or apps.apple.com/account/subscriptions.
• Android: Google Play → Profile → Payments & subscriptions → Subscriptions, or play.google.com/store/account/subscriptions.

Cancel at least 24 hours before the renewal date. Pro stays on until the end of the year you've paid for. Deleting the app doesn't cancel the subscription.

Apple and Google handle payments, so refunds are requested from them: for the App Store at reportaproblem.apple.com, for Google Play from your order history.

Subscribers get three votes to start and one more each month (monthly votes stop adding up at two). Put several on one request if it matters a lot. When a request is closed, as added or declined, its votes come back to you.
