Powerwall Monitor

Fantastic Sprinkles Pty Ltd
See what your Tesla Powerwall is doing at any time, just by glancing at your wrist! You can launch the app to view an animated display of live data (updated every 10 seconds while it's open), or add a complication to your watch face so that you always know how much battery you have left. Note that complications aren't allowed to refresh as often, so that will update roughly every 30 minutes if you add one.

The app displays solar, battery, grid and home power usage as well as how much charge is left in your Powerwall.

There's two main screens in the app, showing live power data as well as a daily summary total telling you how much solar you've generated, home power used and how much grid power you've imported and exported.

This is a fully stand-alone watch app, that doesn't require a phone app to use.

New to version 1.4, this app now works with solar only installations as well, so you don't need a Powerwall to use it, if you have Tesla solar panels you can see live stats and a day summary for that as well!

We use this app personally every day and will endeavour to keep it up to date and add more features over time.

A Tesla Powerwall or a Tesla Solar Installation, and Tesla account are required to use this app. Your account details are stored in the built in secure Keychain on your watch. They are only transmitted to Tesla's servers for authentication purposes on first login and when your authentication token expires. This app contains no first or third party tracking whatsoever and relies on no third-party libraries. We take great care to respect your privacy and your data remains your data.

This app is not made or endorsed by Tesla. It's built by nerds who couldn't get enough of watching that mesmerising Powerwall animation and wanted it on their watches.
