Connecting to Tesla Gateway

How to Log In

Step 1: Find your Gateway serial number, which is the password for Backup Gateway and Non-Backup Gateway, on the bottom of the home screen in the Tesla app. For Gateway 2, your serial number is in the Tesla app and your password is located behind the cover of the unit.

Step 2: Connect to the Gateway Wi-Fi network, which appears as “TEG-xxx,” where xxx are the last three digits of the Gateway serial number. If you do not see the Wi-Fi network, try moving physically closer to the Backup Gateway. If you still do not see the Wi-Fi network, contact us.

Step 3: After you click on the “TEG-xxx” network, enter the Wi-Fi password found in Step 1.

Step 4: Open a web browser and enter any of the following in the address bar:

  • 192.168.91.1
  • https://teg
  • https://teg-XXX

Step 5: When connecting to a Gateway for the first time, your browser may present a privacy warning. Proceed past the privacy warning and accept the site as safe. To do this, look for 'Advanced' or 'Show Details' and then click 'Proceed to' or 'Visit this Website'.

  • This privacy warning is shown because each Gateway has its own self-signed SSL certificate to support a private connection. These certificates are not pre-registered to be recognized by the browser or certificate authority. Once you accept the site as safe the first time you visit, it will save the certificate to this computer for future use.

Step 6: Once the page loads, click “Login”.

Step 7: Choose the "Customer" login type.

Email: Use the email you use for your Tesla Account.

Password: The first time you log in, your password will be the last five characters of the Gateway password.

Backup Gateway: Last five characters of the Gateway serial number.

Backup Gateway 2: Last five digits of characters on the sticker.

Step 8: Your password can be reset or customized by tapping 'Change or Forgot Password' and following the on-screen instructions.

Update Network Settings

Once you are logged in, follow these steps to change network settings:

Step 1: Select 'Network'

Step 2: Select 'Wi-Fi'

Step 3: Select your home Wi-Fi network and enter your password. For Backup Gateway and Non-Backup Gateway, Wi-Fi network will briefly stop broadcasting while it scans for Wi-Fi networks

Step 4: Wait two minutes and rejoin the Gateway’s Wi-Fi network

Step 5: Refresh the page

Backup Gateway and Non-Backup Gateway are only compatible with 2.4 GHz networks. If you have a dual band router that broadcasts 2.4 and 5.0 GHz networks, for all Gateway types, we recommend selecting the 2.4 GHz network.

The Gateway does not support Wi-Fi connection to Enterprise networks requiring a username or to networks with a Captive Portal log-in.
