Frequently Asked Questions

Do I need a Tesla vehicle to use arbi?

No! arbi is designed specifically to manage your home energy ecosystem. As long as you have a Powerwall installed and linked to your Tesla account, arbi will work perfectly.

Which Powerwall versions are supported?

arbi supports Powerwall 2, Powerwall+, and the new Powerwall 3. It communicates via the official Tesla Fleet API, ensuring compatibility across modern hardware.

What happens if my internet goes down during a Cheeky Charge?

arbi requires an active internet connection to send commands to the Tesla API. If your internet drops during an automated event, the Powerwall will remain in the cheeky charge state until an active internet connection is made.

How does the app connect to my Powerwall?

Tesla Powerwall Elite uses the Official Tesla Fleet API. When you set up the app, you will be redirected to the secure Tesla.com SSO (Single Sign-On) page to authorize the app.

Why use the Fleet API instead of a local connection?

By using the Fleet API, Tesla Powerwall Elite works from anywhere in the world. You don't need to be on your home Wi-Fi to trigger a Cheeky Charge or a Shoulder Charge. Whether you are at work or traveling, you have full professional control over your energy ecosystem via Tesla’s secure cloud servers.

Does this use "Virtual Keys"?

Yes. For advanced commands (like manual grid overrides), the Fleet API utilizes Tesla Virtual Keys. This is the highest level of security Tesla offers for third-party integrations, ensuring that only your authorized device can send commands to your Powerwall.

How does "Shoulder Charging" prioritize solar?

Because the Fleet API provides real-time telemetry, our algorithms can see exactly what your solar panels are producing.

Which devices are supported?

Tesla Powerwall Elite is a native, cross-platform application. By backing this project, you get a license that works across:

Do I need a dedicated server or a Raspberry Pi?

No. Unlike other advanced Powerwall tools, you do not need to set up a Home Assistant, a Raspberry Pi, or a 24/7 server. The app is the server. The intelligence lives directly on your device, handling all the "Cheeky Charge" and "Shoulder Charge" logic locally. For the automated charges to work, the app must be running on at least one of your devices.

Where is my data stored?

Your data stays with you. Because there is no central "Tesla Powerwall Elite" server, your energy history, credentials, and API tokens are stored locally and encrypted on your own device.

Does the app need to be running for the "Smart Charges" to work?

Yes. Since the logic is handled by the app itself, your device (e.g., a wall-mounted tablet or a backgrounded PC) needs to be active to trigger the Cheeky Charge or Shoulder Charge at the correct time.

How many sites can I monitor?

The app features native Multi-Site Monitoring, allowing you to manage everything from a single dashboard. Whether you have one Powerwall at home or five spread across different properties, you can oversee your entire portfolio without juggling multiple accounts or complex server setups.
