I'm like the person you replied to: many of the lights in my house are automated. I also have motion sensors in most of the ground floor rooms, and have hooked the had fireplace up to the system.

We don't touch light switches anymore. You walk into a room, the lights come on - but only if it's near or after dusk, and before sunrise. If there is noone in the room, the lights go off after a few minutes. All of the lights go off after 9pm, because we're in bed by then. When we come home after dark, the lights in the entryways come on, so we don't come home to a dark house.

This also serves as part of the security system: after 9, or when we're out, if the motion sensors detect motion, all of the lights come on in the house (in addition to sirens, etc.)

I think every smart bulb is dimmable, and many change color - either warm/cool or full spectrum. We use this on the holidays, with some of the lights changing to green during halloween, and a combination of red, green, and gold during christmas. The dimming is also intentionally used: the lights are brighter during crepuscular times, and dim as it gets darker.

Finally: I have a little novelty desk lamp my wife bought me: a sisal moon wound through with fairy lights, with a dangling globe filled with more fairy lights. It's cheap, mostly plastic, and I love it. What i don't love is that it's battery powered, and the switch is located on the bottom of the base, so to turn it on I had to pick it up. I put in a wired AA replacement pack that plugs into the wall, and put that outlet on a smart switch; now my fairy lamp turns on a bit before I start getting ready to go to bed, and turns off automatically when I usually put my book down. I don't have to get out of bed to turn it off, but can have it on while I'm reading.

There are other ways we use these smart lights, but those are the main ones. Yes, it's all just convenience and ambience, but so are light bulbs... why not just use candles or oil lamps instead?
