## What is Powerwall Monitor?

This is a Tesla Powerwall monitoring app, for iPhone and Apple Watch.

See what your Tesla Powerwall is doing at any time, just by glancing at your phone, or 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 items 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.

Some recent updates: in version 1.4, this support was added for solar only installations. In version 2.5, we added support for multi-site installations. As of version 2.6, this app now uses the official Tesla API as well.

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

Note:
A Tesla Powerwall or a Tesla Solar Installation, and Tesla account are required to use this app. This app supports Tesla's official API, and doesn't see or store your username or password at any point. This app contains no first or third party tracking whatsoever. We take great care to respect your privacy and your data remains your data.

Disclaimer:
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.

### 4/5 — Settings

*2025-10-27*

I’d love it if this could be landscaped if the user wished. Downloaded, it’s basic, looks great and easy to understand.

Reason, I say it’d be brilliant if we could have the landscape option - look good on the IPad up on the wall as a home monitor.

### 4/5 — Works great. Split screen support would make it awesome

*2025-10-21*

Like the app. It’s serves the purpose. I use an older laptop (iPadOS 17) as a live HA dashboard. Split screen support would make this app awesome as it would allow it to be viewed alongside other HA apps.

### 5/5 — great app

*2025-09-15*

handy! though it would be better to have some sort of spinner over the previous/cached readings to indicate it is fetching new data

### 2/5 — Login failures

*2025-05-04*

The login process is broken. Attempting to “Login with Tesla” gives “Open in Powerwall” in browser (why in a browser, not the app?), clicking “Open” goes right back to the “Login with Tesla” screen in the app. The only other option is “Demo Mode”, which appears to be live, but the information is incorrect.

### 5/5 — Notifications would be very useful

*2025-03-22*

I like to manually switch some household devices on and off depending on kW exported to the grid on a sunny day. It would be very useful if I could set a notification from PWM that, for example, let me know when grid export fell below 4 kW, so I could turn off a device.

### 2/5 — Used to be good but no longer updates in a timely way

*2025-02-14*

As the title says. Last year no problems and worked well but now can be hours between refreshes, so is a little pointless. Something has changed with the app and sadly not for the better.

### 2/5 — No longer updating in a timely fashion

*2025-02-03*

This app worked fine until recently. Now it is very slow to update (as a widget it never does update) on my Apple Watch- sometimes takes over an hour to get new details. Shame as it used to work perfectly.

### 2/5 — Can’t get back from “API test”

*2024-04-14*

4/14/24 after clicking on “API test” in Settings, there is no way to get back to the Home Screen or the settings. App reports power flow to the grid when it is really going to the Powerwalls. I know it isn’t going to the grid, because we are not connected to the grid.   Some previous reviews state issues with excess battery use on the iWatch. Has that been resolved? Since the developer doesn’t respond to the reviews, one has to assume that they haven’t been seen and nothing has been done in response.

### 5/5 — Tut was sie soll

*2024-03-28*

Gute APP für die Apple Watch. Sehr guter Support!

### 1/5 — Can no longer monitor my powerwall since upgrading to version 2.6

*2024-03-27*

Since upgrading to version 2.6 this morning I have been unable to monitor my Powerwall installation with this app.  The app starts but the screen is black and the widgets show all monitored elements as ‘zero’.
