At CES Unveiled in Las Vegas, Greg Price of TandemLED introduces their two-wire system that controls lighting in the Kelvin range. That makes their HomeKit-compatible easier to tune lighting to a color that you like, no hub required. Best of all, theirs is tech that can be incorporated into any fixture, at both the manufacturer and consumer levels.
