Gentle wake up.
I had interior lights that would raise and lower their brightness according to how much light was coming from outside. Also used it to slowly ramp up the exterior light at sunset and lower later in the night.
Philips Hue has its own built in wake-up and sleep routines, as well as natural lighting scenes. If you set them up on that end, you don’t need a smart app
But those gradual activities have to be set in the hue app and are also based on time.
The old way, i had my wake up routine in smartthings and it controlled a number of different activities. If i want to change the time or team i could do that by changing only the smartthings routine.
I just found that the tp-link kasa bulbs have a gradual on built into their bulb controller that is accessible in smartthings. I just replaced several hue bulbs in my house because of this. I just wish the 1000 lumen bulbs were actual 1000 lumens
