Hubs also let you control from anywhere. Hubs have the advantage of not relying on wifi so it won't bog down your signal. That's why I have Lutron smart switches.
I have 14 bulbs/3 strips… and will continue growing the selection. I just purchased more yesterday, my outdoor bulbs were $30 a pop, while I got my indoor bulbs (normal lamp style) for $35 for a two pack from Best Buy. 8 bulbs for $190, or $23.75 per bulb isn’t bad considering what they do, how long they last (I’ve had some for 3+yrs w/ no issues) and without the need of a hub.
