The `sun` component will use your current location to track if the sun is above or below the horizon.
|
|
The sun can be used within automation as [a trigger with an optional offset to simulate dawn/dusk][automation-trigger].
|
|
|
|
[automation-trigger]: /components/automation.html#sun-trigger
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
homeassistant:
|
|
latitude: 32.87336
|
|
longitude: -117.22743
|
|
|
|
sun:
|
|
elevation: 123
|
|
```
|
|
|
|
Configuration variables:
|
|
|
|
- **elevation** (*Optional*): The solar elevation angle is the altitude of the sun. If ommitted will be retrieved from Google Maps.

"service": "switch.turn_on",
|
|
"event": "sunset",
|

"offset": "-01:00:00"
