OpenEVSE

The OpenEVSE integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows you to monitor your OpenEVSE electric vehicle charging station equipped with ESP8266/ESP32-based Wi-Fi connectivity.

Prerequisites

  • The OpenEVSE charger is on the same network as Home Assistant.

Configuration

To add the OpenEVSE device to your Home Assistant instance, use this My button:

OpenEVSE 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 OpenEVSE.

  • Follow the instructions on screen to complete the setup.

Configuration

Sensors

The integration provides the following sensor entities:

  • Charging status: Current operational state of the charger (for example: Connected, Charging, Not Connected)
  • Charge time elapsed (seconds): Duration of the current charging session
  • Usage this session (Wh): Energy consumed during the current charging session
  • Total energy usage (Wh): Cumulative energy consumption of the device
  • Ambient temperature (°C): Environmental temperature reading from the charger
  • IR temperature (°C): Infrared sensor temperature reading (disabled by default)
  • RTC temperature (°C): Real-time clock sensor temperature reading (disabled by default)

Note

The IR and RTC temperature sensors are disabled by default. To enable them, go to the device page, click on the entity, and toggle the “Enabled” switch.

Authentication

If you have configured HTTP authentication on your OpenEVSE charger (recommended for security), the integration will prompt you to enter your credentials during setup. These credentials are stored securely in Home Assistant’s configuration.

Migrating from YAML configuration

Warning

YAML configuration for OpenEVSE is deprecated and will be removed in a future release.

If you previously configured OpenEVSE using YAML in your configuration.yaml file, your configuration has been automatically imported into the UI. To complete the migration:

  1. Remove the openevse or sensor platform configuration for OpenEVSE from your configuration.yaml file.
  2. Restart Home Assistant.

The integration will continue to work using the imported UI configuration.

Troubleshooting

Cannot connect to host

  • Verify that the IP address or hostname is correct.
  • Ensure the OpenEVSE charger is powered on and connected to your network.
  • Check that Home Assistant can reach the charger (they should be on the same network or have proper routing configured).

Authentication failed

  • Double-check your username and password.
  • Verify that HTTP authentication is enabled on your OpenEVSE charger if you’re being prompted for credentials.
  • Try accessing the OpenEVSE web interface directly in a browser to confirm your credentials work.

Removing the integration

This integration follows standard integration removal. No extra steps are required.

To remove an integration instance from Home Assistant

  1. Go to Settings > Devices & services and select the integration card.
  2. From the list of devices, select the integration instance you want to remove.
  3. Next to the entry, select the three dots menu. Then, select Delete.
