For the fan - I like having it turn on in the late afternoon to freshen up the air in the bedroom.
I also really like automatically adjusting the brightness/color temperature of all our lights during the day.
It’s by no means necessary, but I don’t want to go back now.
Thanks. I typically turn on the lights with a wall mounted switch when I walk into a room and turn it off when I leave the room. Never gave brightness or color temperature much thought.
