For Tesla Powerwall owners on macOS

Your Powerwall,
always in view.

Charge, consumption, and where your power's coming from — solar, battery, or grid — sitting quietly in your menu bar. No app to open, no dashboard to check.

Charge

State of charge at a glance, updated continuously — no need to open the Tesla app to check.

Consumption

What your home is drawing right now, in kilowatts, right where you already look.

Source

Whether that power's coming from the sun, the battery, or the grid — color-coded, instantly.

Built native. Not wrapped.

Wattson is Swift and AppKit, not a browser pretending to be an app. It sits in your menu bar without a Dock icon, a hidden Chromium renderer, or a few hundred megabytes doing the job a few kilobytes could.

What “connect” actually means

You sign in on Tesla's own login page — Wattson never sees your Tesla password.
Wattson only ever reads your Powerwall's status. It can't send commands or change any settings.
Your access token lives in your Mac's Keychain — not on our servers, not anywhere else.
Nothing is sold, shared, or used for anything but showing you your own data.

Wattson is finishing up.

The menu bar app is built and working — signed, notarized releases are coming next.
