A:AnswerThese bulbs require the hub in order to be controlled. However, 1 hub can control 60 bulbs. If you don't want the hub you can always go with this bulb: https://www.bestbuy.com/site/sengled-a19-wi-fi-smart-led-bulb-white-only/6320348.p?skuId=6320348
This bulb connects directly to your Wi-Fi without the hub. The reason to go with one or the other depends on how many you plan to deploy. The breakeven point at current prices ($40 hub+2 bulbs and $10 for each additional vs $15 each for the hub free version) is 6 bulbs. If you plan to do more than 6 - go with the hub. Less than 6 - go with the hub free version. I currently have 11 bulbs controlled by my hub and plan to add more (I started with 3 bulbs 7 months ago).
A:AnswerYou don't need to change your light switch but to turn it on/off, yes, you need to keep the power on in order for that to occur using the hue app or Alexa.
A:AnswerOnce you setup the hub with your router, you can unplug it and plug the hub closer to your master bedroom. This will allow you to use it as a “WiFi” system.
A:AnswerYes. The app controls the dimming setting and can be set to 3 different schedules per bulb. Works best with smart hub, though. Bestbuy has had this and the Amazon dot bundled for $50 from time to time
