Connecting Powerwall to Wi-Fi

Tesla App Connecting Powerwall to Wi-Fi

Connecting to Wi-Fi provides your Powerwall with a more stable connection to Tesla. With the Tesla app, you can configure the Wi-Fi settings of your Powerwall+ or Powerwall with Gateway 2. You can also update your network settings if you change your router or update your network connection. Your Powerwall is supported on 2.4 GHz networks with WEP/WPA1/WPA2 personal security as well as hidden SSIDs.

There are two methods for your Gateway to connect to or update your Powerwall’s Wi-Fi connection. The app will automatically select the connection method depending on your Powerwall’s internet connectivity.

If Powerwall is Disconnected from the Internet

Your Powerwall will always attempt to maintain an internet connection. However, it may disconnect from the internet if your Wi-Fi network has changed or if the local cellular network has gone offline. When your Powerwall is completely offline, a ‘Device Offline’ banner will be visible on the home screen, and recent power flow or energy data will not be visible. To configure Wi-Fi, go near your Powerwall and Gateway, and follow the steps below.

Step 1: In the Tesla app, locate your home energy site.

Step 2: Select ‘Settings.’

Step 3: Select ‘Configure Wi-Fi’ at the bottom of the screen.

Step 4: Follow the in-app steps to locate and scan your Gateway password QR code.

Step 5: Accept the request to join your Powerwall's local ‘TEG-xxx’ Wi-Fi network, where ‘xxx’ are the last three alphanumeric characters of your Powerwall serial number. Wait a few minutes for your phone to connect to Wi-Fi.

Step 6: Select your home Wi-Fi network, and then enter your network password.

Step 7: Tap ‘Connect’ to connect your Powerwall to Wi-Fi.

Note: Once connected to your home Wi-Fi, your Powerwall’s power flow and energy data will begin syncing with the Tesla network. If you are unable to connect your system to Wi-Fi, learn more about alternative internet connectivity options.
