Amazon introduced a new Echo device specifically made for home automation, the Echo Plus.
It's still a hands-free speaker with the Alexa assistant like the previous Echo (which received a full revision as well), but it now also has a built-in ZigBee hub. That means you can control ZigBee based home automation products without the need for an extra hub.
There is no built-in Z-Wave radio (yet?), but you can still link a separate Z-Wave hub to access supported Z-Wave devices.
The Echo Plus will be available on Oct 31, 2017. To help launch it, for a limited time a free Philips Hue Bulb is included.
