I replaced all switches in my apartment with Lutron smart dimmer & smart switches, and have Philips Hue in some lamps.

- While the color change feature is mostly gimmick, the adjustable color temperature is really useful. You can't get that in a smart dimmer / switch

- Dimmers don't work very well with LED bulbs, and they can flicker at low end of brightness setting

- At least the Lutron smart switches I used don't work very well with LED lights with minimal power draw. Apparently due to the way they work, in off state, there still will be a little bit of current leaking to the circuit, which would be enough to power some LED bulbs
