Lights are extremely powerful but people always seem to focus on only half the equation. Waking up to light is a million times better than waking up to sound. My lights dim and turn off around 9:30pm and turn on at 5:30 am and brighten until 6:00 am. I wake up without any grogginess at all. It's amazing.
Some of the best sleep I've ever had was while camping, where tent is pitch black at night and a soft diffuse glow in the morning.
I go camping and everything is noisy or hot as soon as the sun comes up. Worst sleep I could ever get.
This is the use case that'll probably get me to invest in IoT products (which I otherwise don't want in my home).
(I have one of those Philips alarm clocks with the "sunrise" light, but it doesn't light the room enough to wake me.)
Sleep as android's automation feature coupled with home assistant allows me to do things like turn on the lights when my alarm turns on (or offset by some time).
