Home Assistant has a built-in component called `device_sun_light_trigger` to help you automate your lights. The component will:
|
|
|
|
* Fade in the lights when the sun is setting and there are people home
|
|
* Turn on the lights when people get home after the sun has set
|
|
* Turn off the lights when all people leave the house
|
|
|
|
This component requires the components [sun](/components/sun/), [device_tracker](/components/device_tracker/) and [light](/components/light/) to be enabled.
|
|
|
|
To enable this component, add the following lines to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry

|
device_sun_light_trigger:
|
|

|
|
light_profile: relax
|
|
device_group: group.my_devices
|
|
disable_turn_off: 1
|
|
```
|
|
|
|
