All our Philips Hue products and Amazon products works together, straight out of the box with a Philips Hue Bridge and the Amazon Alexa smart home Skill.
For the Amazon Echo PLUS you don’t need a Philips Hue bridge. Philips Hue lights may be turned on and off, dimmed up and down using voice commands, and Amazon Alexa app thanks to the integration with Echo Plus, which offers a built-in smart home hub for simple setup and control of ZigBee-enabled lights and other devices. You can just use them together, simply ask Amazon Echo PLUS: ‘Alexa, discover lights’.
