If you're using the "C Sleep" version of the bulbs, you'll be able to ask the Assistant to change their color temperature between warm and cool white light tones, too. You'll also find controls for all of this directly in the Google Home app on your Android or iOS device, along with options for setting scheduled lighting changes and crafting custom, voice-activated routines.

Even better -- your Home smart speaker will act as a relay and let you access the bulbs even when you're out of Bluetooth range. No additional hub hardware or plug-in device is needed at all. Cya, C Reach.
