The **Tesla Wall Connector** {% term integration %} allows you to integrate your Gen 3 [Tesla Wall Connector](https://www.tesla.com/support/charging/wall-connector) with Wi-Fi into Home Assistant.

{% include integrations/config_flow.md %}

{% configuration_basic %}
Host:
  description: The hostname or IP address of your Tesla Wall Connector.
Single-phase / Split-phase electrical service:
  description: Enable this option if your Wall Connector is powered by single-phase or split-phase electrical service. This affects the calculation of the **Total power** sensor. Leave it disabled for three-phase supply. Defaults to disabled.
{% endconfiguration_basic %}

## Configuration options

After setup, you can change the electrical service type. Go to {% my integrations title="**Settings** > **Devices & services**" %}, select the **Tesla Wall Connector** integration, and then select **Configure**.

{% endconfiguration_basic %}

## Supported functionality

The Tesla Wall Connector integration provides sensors and binary sensors that you can show on dashboards, use in automations, and add to the [Energy dashboard](/docs/energy/).

### Sensors

- **Lifetime energy**: Running total of energy used by the Wall Connector.
- **Session energy**: Energy used during the current charging session.
- **Status**: Present status of the Wall Connector. Possible states are **Booting**, **Vehicle not connected**, **Vehicle connected**, **Ready to charge**, **Negotiating connection**, **Error**, **Charging finished**, **Waiting for car**, **Charging (reduced)**, and **Charging**.
- **Grid frequency**: Grid frequency of the incoming AC power.
- **Grid voltage**: Grid voltage of the incoming AC power.
- **Handle temperature**: Temperature of the Wall Connector handle.
- **MCU temperature**: Temperature of the Wall Connector main computing unit.
- **PCB temperature**: Temperature of the Wall Connector power control board.
- **Phase A current**, **Phase B current**, and **Phase C current**: Current for each incoming AC electricity phase.
- **Phase A voltage**, **Phase B voltage**, and **Phase C voltage**: Voltage for each incoming AC electricity phase.
- **Total power**: Total power reported by the Wall Connector. If the Wall Connector uses single-phase or split-phase electrical service, enable **Single-phase / Split-phase electrical service** so Home Assistant calculates this sensor correctly.
- **Vehicle current**: Current being delivered to the connected vehicle.
- **Wi-Fi RSSI**: Wi-Fi signal strength reported by the Wall Connector.
- **Status code**: Error code generated by the Wall Connector. This diagnostic sensor is [disabled by default](/docs/configuration/customizing-devices/#disabling-or-enabling-an-entity).

### Binary sensors

- **Contactor closed**: Whether the Wall Connector is currently charging.
- **Vehicle connected**: Whether a vehicle is connected.

### Device information

The device page shows the Wall Connector model, model ID, serial number, and firmware version.

## Data updates

The Tesla Wall Connector integration {% term polling polls %} the device every 30 seconds.

## Energy dashboard

Energy usage can be added to the built-in [Energy dashboard](/docs/energy/) using the **Lifetime energy** sensor.

To add the Tesla Wall Connector to your Energy dashboard:

1. Go to {% my energy title="**Settings** > **Dashboards** > **Energy**" %}.
2. In the **Electricity grid** section, select **Add consumption**.
3. Select the Tesla Wall Connector **Lifetime energy** sensor.
4. Select **Save**.
