Amazon Echo (more commonly known as Alexa) is a product created by Amazon.com that's designed for home automation. With a simple voice command, Alexa can perform a number of services for the owner such as turning lights on and off, locking or unlocking doors, changing thermostats, checking on cameras, and so on. These commands can even be given from a device while the user is away from home, but 10 years ago something like that would have been more likely seen in a sci-fi movie. It's initially release date wasn't until November 2014!
