Google's Android Wear smartwatches have had their developer units dished out and more details are starting to dribble out each day. The latest is a video showing just how useful the voice automation could be.

The video, from developer Doug Gregory, show how Google's voice controls can work lights and even his garage door. It also shows photos can be set to on and off, open and close. That way when you close the garage door, for example, you can see it shut.

In the video the turning on of the light appears to suffer a bit of a delay. This could be due to the connection or simply the fact that this is a beta version.

AutoVera is the name of the home automation software while Autovoice is what lets you control everything by speaking. Android Wear will be on sale officially from July 7 with the launch of the Moto 360 to follow later in the summer.
