Amazon Echo is a range of hands-free smart speakers with a built-in virtual assistant, Amazon Alexa. Amazon Echo, along with Alexa, follows voice-controlled commands and allows you to accomplish a range of tasks including making phones calls, settings alarms and reminders, playing music, catching up on news and can even switch on the lights in your house. But Amazon Echo is not always error-free and you may find it difficult to connect some devices. If you find that an error prevents Amazon Echo Alexa from discovering Hue then you can contact Amazon Echo customer support whenever you need help.
