Tesla Wall Connector

The Tesla Wall Connector integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows you to integrate your Gen 3 Tesla Wall Connector with Wi-Fi into Home Assistant.

Configuration

To add the Tesla Wall Connector device to your Home Assistant instance, use this My button:

Tesla Wall Connector can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Manual configuration steps

If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:

  • Browse to your Home Assistant instance.

  • Go to Settings > Devices & services.

  • In the bottom right corner, select the Add Integration button.

  • From the list, select Tesla Wall Connector.

  • Follow the instructions on screen to complete the setup.

Host

The hostname or IP address of your Tesla Wall Connector.

Single-phase / Split-phase electrical service

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.

Configuration options

After setup, you can change the electrical service type. Go to Settings > Devices & services, select the Tesla Wall Connector integration, and then select Configure.

Single-phase / Split-phase electrical service

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.

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.

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.

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 pollsData polling is the process of querying a device or service at regular intervals to check for updates or retrieve data. By defining a custom polling interval, you can control how frequently your system checks for new data, which can help optimize performance and reduce unnecessary network traffic.

Energy dashboard

Energy usage can be added to the built-in Energy dashboard using the Lifetime energy sensor.

To add the Tesla Wall Connector to your Energy dashboard:

  1. Go to Settings > Dashboards > Energy.
  2. In the Electricity grid section, select Add consumption.
  3. Select the Tesla Wall Connector Lifetime energy sensor.
  4. Select Save.
