A:Answer If you buy any Philips Hue lights, you will need the Philips Hue hub. The bulbs won't communicate directly with the Echo--they will only "talk" with their own branded hub. However, the Echo will allow you to use your voice to turn on/off your lights, once you teach Alexa the skill so that SHE can talk to the Philip Hue hub. So yes, you need to buy a kit that includes the hub (like this one does), unless you already own a Philips Hue hub (or have a friend who has an extra to give you).
