1. How to setup sunrise alarm (sunrise-like wakeup)
Enable Settings → Services → Smartlight → Use smartlight
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.
Use cable-type Sleep Mask as a smartlight: Connect using Smartlight → Use Sleep Mask.
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 → Sound delay 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.
Without the delayed sound start, you can control the speed of 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.
Sunrise alarm with delayed sound - start of the alarm sound is set for 3 minutes = the light level will start increasing from alarm time, till the start of the sound. So after 3 minutes, the smart lights will be at the highest brightness. Duration of gentle volume increase does not play any role.
