Cortana is a virtual assistant created by Microsoft for Windows 10, Windows 10 Mobile, Windows Phone 8.1, Invoke smart speaker, Microsoft Band, Xbox One, iOS, Android, Windows Mixed Reality, and soon Amazon Alexa
With integration to Control4 Home owners can now control their homes verbally to tell their thermostats to go to a specific setpoint, dim their lights to a specific level, select a channel on their TV's, turn the whole house off or even broadcast text to speech announcements throughout their home.
This integration is extremely interesting as a large portion of people own a PC with Windows 10 so most study rooms can now have voice control over your Control4 system. On top of this the Xbox One is an extremely popular gaming console which can also use Cortana for voice control. This can be a great conversation starter for voice control with existing customers who already own Windows 10 PC's and Xbox One devices.
Integration is achieved via the Chowmain IFTTT driver for Control4. Linked below is a document detailing how to program the Chowmain IFTTT driver to work with Google home.
