Sunrise

The Sunrise trigger fires the moment the sun rises above the horizon at your location. Home Assistant calculates the exact time for every day of the year from your home location, so the trigger stays accurate as sunrise shifts through the seasons.

Use it to open blinds, turn off outdoor or night lighting, or start your morning routine the moment the day begins.

Using this trigger from the user interface

If you prefer building automations visually, Home Assistant walks you through this trigger step by step. You pick what to watch, tweak a few options, and save. No YAML knowledge required.

To use this trigger in an automation:

1. Go to Settings > Automations & scenes.
2. Open an existing automation, or select Create automation > Create new automation.
3. In the When section, select Add trigger.
4. From the search box, search for and select Sun: Sunrise.
5. Select Save.

Using this trigger in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this trigger as sun.sunrise. It has no options:

trigger: sun.sunrise

This fires every day, the moment the sun rises above the horizon.

Good to know

• This trigger does not use a target. It applies to the sun at your configured home location.
• The trigger fires exactly at sunrise. To fire a fixed amount of time before or after sunrise, use the classic sun trigger, which accepts an offset. For light-based timing that adapts to the seasons, use Sun elevation crossed threshold instead.
• To react to the first light before sunrise, use Dawn. To react when the sun goes down, use Sunset.

Try it yourself

Ready to test this? Go to Settings > Automations & scenes, create a new automation, and add this trigger. Save the automation, then change the state of the targeted entity to watch the trigger fire on your actual entitiesAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more].

For this trigger, there is no target entity to change. To test it, wait for the next sunrise, or temporarily switch to a trigger you can control while you build the rest of the automation.
