That's a great question, Ron! You can definitely control your SmartThings Smart Bulb with Alexa. Please note that the Smart Bulb does require the SmartThings Hub in order to function and will not connect to Alexa directly. You can learn more about connecting SmartThings and Alexa on our Support page here -- https://support.smartthings.com/hc/en-us/articles/205275404-How-to-connect-Amazon-Alexa-with-SmartThings.
