Amazon announced that they are now supporting the Belkin Wemo and the Phillips Hue on the Amazon Echo. This is great unless you already invested in a bunch of z-wave devices and gateway. If you have a Vera Z-wave home automation gatway take a look at my Amazon-Echo-HA-Bridge on github. It emulates a Phillips Hue to allow the Amazon Echo to turn on/off my lights/fan/stuff!
Alexa: main screen turn on.
