Reconnecting your Tesla Powerwall to Wi-Fi

How to get your Powerwall back online in the Tesla app after a router or Wi-Fi password change.

Your Powerwall needs the internet so you can see it in the Tesla app and so it can receive software updates. If you change your router or Wi-Fi password, it may show as offline.

Before you start

  • Have your Wi-Fi name and password ready.
  • Make sure you're logged into the Tesla app on the account linked to your Powerwall.
  • Stand near your Powerwall equipment with your phone.
  • Tesla says you need at least two bars of Wi-Fi signal near the Gateway.

Reconnecting

The steps depend on which Powerwall you have. The Tesla app guides you through it.

  1. Open the Tesla app and go to your home energy site.
  2. If it shows Device Offline, tap it and follow the on-screen steps. Powerwall 3 pairs with your phone by Bluetooth.
  3. On older Powerwall systems, look for Configure Wi-Fi in the site settings and follow the prompts.
  4. If your Powerwall is still online through mobile data or a cable, you can use Network Setup to choose your new Wi-Fi.
  5. Pick your home Wi-Fi, enter the password and tap Connect. This can take a few minutes.

Some older Gateways only work with 2.4 GHz Wi-Fi, so pick that network if you have a choice.

Things to avoid

  • Wi-Fi networks that need a login web page, like some hotel-style setups, won't work.
  • If your signal is weak, a Wi-Fi extender can help.

Data can take up to a day to sync after reconnecting.
