Powerwall Monitor is a Tesla Powerwall monitoring app designed for iPhone and Apple Watch. With this app, you can easily keep track of what your Tesla Powerwall is doing at any time, right from your phone or wrist. The app provides an animated display of live data, which is updated every 10 seconds while the app is open. Additionally, you can add a complication to your watch face to always know how much battery power is left, although it will update roughly every 30 minutes.

The Powerwall Monitor app showcases solar, battery, grid, and home power usage, as well as the remaining charge in your Powerwall. It offers two main sections: live power data and a daily summary total. The daily summary provides information on solar generation, home power usage, and grid power import and export.

One great feature of this app is that it can run standalone on your Apple Watch once you've signed in. Furthermore, the latest version of the appnow supports solar-only installations as well, meaning you don't need a Powerwall to use it. Version 2.0 introduces support for 2FA/MFA accounts, and version 2.5 now supports multi-site installations for users with multiple Powerwalls.

It's worth noting that a Tesla Powerwall or Tesla Solar Installation, as well as a Tesla account, are required to use this app. Your account details are securely stored in the Keychain on your device and are only transmitted to Tesla's servers for authentication purposes. Powerwall Monitor is not made or endorsed by Tesla; it is an app created by enthusiasts who wanted to have the mesmerizing Powerwall animation on their watches. The app respects your privacy and does not include any tracking features.
