Tesla Wall Connector for Home Assistant (built-in integration)

About

Tesla Wall Connector is a built-in integration that reads data from a Tesla Wall Connector charger over the local network. It adds binary sensors for whether the contactor is closed and whether a vehicle is connected. Sensors cover phase currents, grid voltage and frequency, session and lifetime energy, handle, MCU and PCB temperatures, and charger status. An option tells the integration whether the charger runs on single-phase or split-phase service, which changes how the total power sensor is calculated; it stays off for three-phase supply. Home Assistant can find the charger on the network and offer to add it, and setup is done in the UI with the charger's hostname or IP address.

Setting it up

Home Assistant usually finds it on the network and offers to add it. It can also be added by hand under Settings, Devices and services.

Configure Tesla Wall Connector

HostHostname or IP address of your Tesla Wall Connector.
Single-phase / Split-phase electrical serviceEnable if your Wall Connector is powered by single-phase / split-phase electrical service. This affects the calculation of the Total power sensor. Leave disabled for three-phase supply (default).

After setup

Single-phase / Split-phase electrical serviceEnable if your Wall Connector is powered by single-phase / split-phase electrical service. This affects the calculation of the Total power sensor. Leave disabled for three-phase supply (default).
