A:Answer Hi there! You won't need anything extra to control your Sengled smart light bulbs through Alexa, though you may need a hub for the bulbs themselves depending on which kind you get. Assuming that you already have them set up and function though, all you need to do is activate the Sengled skill in the Alexa app on your phone to get things working. To do that open the Alexa app (the same thing you used to set up the Echo Dot) and select "More" at the bottom right. Next select "Skills & Games", and select the search icon (looks like a magnifying glass) at the top right. Search for Sengled then select Sengled Home. Select Settings and sign into your Sengled account. Once you've finished that, you may need to search for new devices using the Device option at the bottom of the app. Once you've done that, you are good to go! You can edit what your lights are called and what rooms they're in all via the Alexa app. Hope this helps, have a great day!
