My solution was to add Shelly relays behind all of my “dumb” switches. They keep power always on and essentially turn the switch into a smart button to dim or brighten my Lifx lights. This way I get circadian & party lighting while still maintaining the convenience of physical light switches!

And to parent question: Lifx still has the best color/brightness of any smart bulb and they’re IMO the best. Just make sure your WiFi can handle it.
