The device is a nine-inch-tall speaker and a set of microphones, and has its default wake
word set to “Alexa.” Just as with Siri, you can command the Echo to tell you the weather by
saying “Alexa, what is the weather like today?” or ask it trivia questions such as “Alexa, how
tall was Michael Jackson?”
The Echo can also be configured to turn Philips lightbulbs (discussed in Chapter 1) on or
off. As with the hue iOS app, the Echo app can access the hue bridge once you press the but-
ton on the bridge to prove physical ownership. It is possible to specify a selection of hue lights
to control by placing them into a specific group (e.g., Lights, as shown in Figure 8-2).
