r3mcos3 · December 17, 2025, 6:12pm

Alarm Light

Wake up with lights that turn on before your phone alarm!

Features

Alarm Integration - Syncs with your phone’s next alarm sensor
Gradual Wake-up - Lights turn on 5-60 minutes before alarm
Presence Aware - Only triggers when you’re home
Darkness Check - Only activates when it’s dark outside
Day Selection - All days, weekdays only, or weekends only
Adjustable Brightness - Configure the perfect wake-up brightness

Requirements

Home Assistant 2025.12.0+
Next Alarm sensor (Android: built-in, iOS: requires Shortcuts workaround)
Person entity
Light entity

Android Setup

Install Home Assistant Companion App
Enable “Next Alarm” sensor in Companion App settings
Sensor appears as sensor.phone_name_next_alarm

iOS Setup

iOS doesn’t natively expose alarm data. Use iOS Shortcuts to sync your alarm to an Input Datetime helper. See iOS guides in the README.

Person	Person to check if home	-

Hi

Thanks for using the blueprint an making it your own version,
my wife has an iphone and no alarm sensor, so i have no usecase for it.

but anybody is free to use the blueprint and making his own version of it.
