Do you remember that video in which they started a car using Siri? Well, the video you see on these lines is created in the same way, using SiriProxy, a proxy server external to Apple where requests are redirected instead of going to the Apple server, in this way you can configure all the external commands you can imagine.
In this case Siri is used to control the whole house: close the curtains, turn on the fan, turn off the light (It even distinguishes different lights), for this you already have to have a home automation, what Siri does is the remote control function, but simply using the voice.
Again it shows that Siri's capabilities are impressive in the near future.
With the voice of hal9k, it would be the ideal house of terror! 😛
