The aurora platform uses the NOAA Aurora Forecast service to let you know if an aurora might be visible at your home location in the next 30 minutes, based off of current solar flare activity.

This service gives a number 0-100 representing the current likelihood of visible auroras at your latitude/longitude. By default this sensor is set up to trigger when the reported likelihood for your location is > 75. It updates every 5 minutes.


Adding Aurora to your Home Assistant instance can be done via the user interface, by taking the following steps:

  • Browse to your Home Assistant instance.

  • In the sidebar click on Configuration.

  • From the configuration menu select: Integrations.

  • In the bottom right, click on the Add Integration button.

  • From the list, search and select “Aurora”.

  • Follow the instruction on screen to complete the set up.

After completing, the Aurora integration will be immediately available for use.

You can configure multiple locations by adding the integration multiple times.


Once installed you can adjust the threshold for this location by clicking on the Options link on the integration.


The integration will add a two sensors for each location you configure:

Sensor Type Values Description
binary_sensor on/off on = high chance of Aurora visibility, off = low chance of visibility
sensor % value Percentage chance of visibility
