4. Guide

4.1. How to setup sunrise alarm (sunrise-like wakeup) ?

  1. Enable Settings → Smartlight → Use smartlight

  2. Select your smartlight:

    • Use phone’s screen as a smartlight: Enable Smartlight → Use screen light

    • Use a smartbulb as a smartlight: Connect using Smartlight → Philips HUE, IKEA Trådfri (disconnected)

    • Use Sleep Phaser as a smartlight: Connect using Smartlight → Sleep Phaser (disconnected) and enable Smartlight right under it.

After you’ve done the above steps to connect and enable the smartlight of your choice, all of your alarms will turn on the smartlight when they start ringing. Now, to have a truly sunrise wakeup, you probably want the smartlight to turn on before the alarm rings.

To set that up, head to Settings → Alarms → Alarm sound start and set it to some period. At the time of the alarm, only the smartlight will turn on at the lowest brightness and gradually brighten up until the set period passes. Then the alarm starts ringing.

You can adjust the speed of the sun-rise effect by changing the period of Gentle volume increase. The longer the period is, the longer it takes to get from dark to full light.
