The sun integration will use the location as configured in your Home Assistant configuration to track if the sun is above or below the horizon. The sun can be used within automations as a trigger with an optional offset to simulate dawn/dusk or as a condition with an optional offset to test if the sun has already set or risen.

Configured by default

This integration is by default configured and installed, and you don’t need to configure it yourself, unless you’ve disabled or removed the default_config: line from your YAML configuration.

If that is the case, you can configure it as described in the next paragraphs.


To add the Sun integration to your Home Assistant instance, use this My button:

YAML Configuration

Alternatively, this integration can be configured and set up manually via YAML instead. To enable the sun integration in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry

Key name Description
