Monitoring from your Home Network
Enhanced Connectivity and Customer Access
The Powerwall system incorporates enhanced authentication and communication protocols that enable you to connect to the system directly over your home network or over the Wi-Fi network hosted by the Tesla Gateway. A dedicated customer login allows homeowners to see system information and directly update network settings, while protecting advanced commissioning settings with a separate login for installers.

- View a summary of product serial numbers, current firmware version, and system settings
Connecting to the Gateway
If your system is already connected to your home network with a wireless or a wired connection, you can navigate to the Powerwall Wizard landing page from a standard web browser.
- Launch a browser using any device connected to your home network.
- Enter https://teg-xxx, where xxx is the last 3 digits of the Gateway serial number.
If your system is not connected to your home network, you can connect to the Wi-Fi network hosted by the Gateway.
1. Using a Wi-Fi capable computer, tablet, or phone, connect to the Gateway Wi-Fi network, which appears as “TEG-xxx,” where xxx is the last 3 digits of the Gateway serial number.
2. Wi-Fi Password: Enter the full serial number of the Gateway:
- If the serial number starts with an “S,” enter the full serial number of the Gateway as it appears on the serial number sticker (without parentheses or colon).
- If the serial number does not start with an “S,” enter an uppercase “S” and follow with the full serial number of the Gateway as it appears on the serial number sticker.

NOTE: If the connection to the Gateway fails repeatedly, try clearing the browser cache, deleting cookies, and relaunching the browser before connecting.
When you first connect, you may see a privacy warning, which only indicates that the browser does not recognize the Gateway certificate. It is safe to click through this warning and proceed with the connection to the Gateway.

Enter the email address you use for your Tesla account. For the password, enter the last five characters of the Gateway serial number.
If you do not know your password, you can reset it by clicking "Change or forgot password" and following the on-screen instructions. Changing your password requires you to toggle the Powerwall switch off and then back on.
