Home Assistant Blueprint: Wake-up light alarm with sunrise effect
Raw
wake-up-light-alarm-with-sunrise-effect.yaml
blueprint:
name: Wake-up light alarm with sunrise effect
description:
"A wake-up light alarm with brightness and color temperature sunrise effect.
Note: Requires date_time_iso sensor in configuration, not manually executable!"
domain: automation

input:
light_entity:
name: Wake-up light entity
description:
The light to control. Turning it off during the sunrise will keep
it off. Color temperature range is auto-detected.

name: Manual alarm time
description:
Time to trigger alarm every day if timestamp sensor is not set.
Settings at or shortly after midnight will not work as expected!
default: "7:00:00"
selector:
time: {}
check_entity:
name: Additional entity to check before sunrise is triggered
description:
If set, checks if entity is 'on' or 'home' before triggering. Use
e.g. a (workday) sensor, device_tracker or person entity.
