Connecting the Philips Hue lights to the Amazon Echo or Echo Dot—or any of Amazon's Alexa-enabled devices—is fairly easy, but if you want to do more than just dim and brighten your lights, it will take a few more steps. Here’s how to do it.
1. Open the Alexa app, and Select Smart Home from the side menu (press the three horizontal lines in the upper left-hand corner of the screen).
2. Select Add Device in the Devices section.
3. Press the button on the Philips Hue bridge.
4. A screen will appear, saying Alexa is discovering devices; after, your Philips Hue bulbs should appear in the Devices section of the Alexa app.
5. Group lights with other smart home devices. Under the Groups tab in the Alexa app, you can select multiple smart home devices so that you can control them as one. This is especially handy if you're grouping them by room. You can either add your Hue lights to an existing group, or create a new group.
6. Control Philips Hue lighting scenes. If you've created a scene in the Philips Hue app, you can discover and control it through Alexa. Select the Scenes tab, and scroll to the one you want. This tab also displays scenes created by other apps, such as the Logitech Harmony remotes, so it can get confusing as to what scene you want to activate.
How to Change the Color of Your Philips Hue Lights Using Alexa
If you have Philips Hue lights that can change color, you can control what color they change to from within the Alexa app.
1. From the Devices menu, select the light whose color you wish to change. Here, you can also turn the light on and off, adjust its brightness, and change its name.
2. Press the Set Color button at the bottom.
3. Select the color you want. Note that the Alexa app limits you to 16 colors; if you are looking for more options, you can verbally say one of the hundreds of colors that work with Alexa, use the Philips Hue app itself, or set up a custom command using IFTTT.
How to Change the Color of Your Philips Hue Lights Using Alexa and IFTTT
You can also change the color of your lights by linking your Alexa account to IFTTT, and creating an applet.
7. Open the IFTTT app (or website) and select Create an Applet.
8. Press the This button. This will let you select a trigger.
9. Select the Amazon Alexa icon.
10. Choose "Say a specific phrase.” This will activate the Echo when you say “Alexa trigger…”
11. Enter the phrase you wish to use. If you want the lights to turn blue, type “lights to blue” and press Next.
12. Select “That”.
13. Scroll down and select the Philips Hue icon.
14. Choose Change Color. Here, you can select not just the color you want the lights to change to, but also which lights you want to change color. Then press Next.
16. Press Finish in the following screen to activate the applet. Here, you can also specify whether or not you want to receive a notification every time the applet runs.
Keep in mind that if you want to simply turn the lights on or off, you have to say “Alexa, turn living room lights on.” However, if you’re going through IFTTT, you’ll need to say “Alexa, trigger lights to red.”
