That’s the other (mostly) good thing about… they’re Wi-Fi native and don’t use any sort of hub.
Their iOS app is reasonably decent, and there are honesceeen widgets.
Easy to build fairly advanced automations… for instance I have a rule that turns my bedside fan off and turns the bedroom lights on that runs 5 minutes before my alarm goes off, weekdays only.
Most of what I use are their bulbs, which are both relatively cheap ($30 for a 4 pack), with excellent CRI, variable color temp (including a nightshirt style automation that goes whiter during the day, and both warmer and dimmer at night), and full RGB color.
I probably wouldn’t recommend them for a whole home setup (you’d need pretty serious Wi-Fi routers) but for a case like mine where I’m only using it in a few rooms, it’s great.
