Use the Tesla app to control, schedule and get data on your Wall Connector, whether you own a Tesla vehicle or another electric vehicle. To complete your Wall Connector setup, follow the recommended steps to register your Wall Connector and connect it to your home Wi-Fi network.

Commissioning and Connecting to Wi-Fi

Below is a step-by-step guide for the Commissioning and Wi-Fi Connectivity process. If you or your installer have already registered and connected your Wall Connector in the Tesla app, there is no need to continue below.

Wall Connectors automatically receive firmware updates when connected to Wi-Fi. The first step for all troubleshooting is to ensure your Wall Connector is commissioned correctly so that it can charge properly and download the most recent firmware for the best performance and latest features.

Note: Before following the steps below, have your Quickstart Guide and home Wi-Fi network password ready and ensure your Wall Connector is unplugged from your vehicle. Keep your Wall Connector unplugged from your vehicle throughout the entire commissioning process. If you lost your password and cannot access your Quickstart Guide, use the Diagnose button below. Have your Tesla part number and Tesla serial number available.

To commission your Wall Connector, the setup is completed within the Tesla One app.

To successfully commission the Wall Connector, scan the QR code located on the front of the installation Quickstart Guide included with the packaging. This QR code provides the unique credentials to connect to the unit, enable power sharing, connect to Wi-Fi, and set the circuit breaker rating and output amperage.

Once set-up is complete in the Tesla One app, residential customers can register their Wall Connector in the Tesla app to access more features, including charging stats and history.
