You can communicate by WiFi with it to turn it on and off and dim it, is my guess. Seems like overkill.
Sounds like a lightbulb for insufferable people who like to brag about their lightbulbs ... along with everything else.
But you can put a speaker inside that lightbulb and listen to music in your kitchen (via the light fixture) from your streaming computer in a nearby room.
Of course it isn’t a stretch to make such data transfer 2-way and include a microphone (and or cam) inside that “smart” bulb.
Be seeing you.
