From the manual The Wall Connector is equipped with Wi-Fi and communicates with local site routers, vehicles, mobile devices, other Wall Connectors, and other Tesla products. Host Access Point The Wall Connector hosts a WPA2 password-protected 2.4 GHz, 802.11 Wi-Fi access point network for easy commissioning and connection to other devices. The unique SSID Wi-Fi network name and WPA2 password for connecting to the Wall Connector are printed on a label on the back of the unit and on the front cover of the included Quick Start Guide. The Wall Connector commissioning process makes it easy to configure circuit breaker size, Wi-Fi connection, and power sharing options. 1. Turn on the corresponding branch breaker on the Wall Connector to energize the unit. Upon startup, the Wall Connector will display a green LED for 10 seconds to indicate the maximum circuit breaker that is set. 2. Use a Wi-Fi-enabled device, such as a smartphone, to connect to the SSID Wi-Fi signal broadcast by the Wall Connector. Joining the Wall Connector network can be done by scanning the sticker QR code on the cover of the Quick Start Guide or by manually selecting the network and entering the WPA2 password (located on the sticker on the cover of the Quick Start Guide). Note: The Wi-Fi network only broadcasts for 5 minutes. To force the Wall Connector to broadcast the SSID again, press and hold the button on the charging handle for 5 seconds or turn the circuit breaker off and back on. Note: If you are unable to connect to the Wall Connector SSID, turn off cellular data on your mobile device and try again. Scan the QR code below on a device connected to the Wall Connector to access the commissioning interface in your web browser. Or manually enter the URL address (http://192.168.92.1) in your web browser. Follow the on-screen commissioning instructions in your web browser to assign the Wall Connector to its own circuit breaker and connect it to your local site's Wi-Fi network.
