A:Answer Hi Nancy, both of the answers below are correct, but I'd like to add to both of them. To use our bulbs with Alexa, you will need a C by GE hub. This includes the C-Reach which was listed below, but, you can also use any of our other hubs. This being the C-Start Smart Switch or the C by GE Smart Plug. You'll want to have all of your devices (bulbs and hub) added to the C by GE app, then you can enable the C by GE Skill in the Alexa app. Once this is done, you can sync your devices over to Alexa. If you have any further questions about this, please give us a call at (844) 302-2943. Thank you for the question and have a great day!
