Build a versatile home automation system from scratch. There are many ways of controlling home appliances with your smartphones, voice, gestures, etc. This book dives into the many options for for communicating with appliances wirelessly and we''ll discuss and implement the leading protocols in the field.
In first few chapters, you will develop a basic understanding of the Raspberry Pi and how one can control it wirelessly from anywhere in the world. Then you''ll get to know about the local server for your home automation projects and control the Raspberry Pi GPIOs using smartphone and web apps. Every appliance will be able to talk to each other, as well, with the help of mesh networking, which you''ll learn to implement. The user interface is also an important aspect of handling all the appliances, so you''ll create your own user dashboard using OpenHAB. From there, you can monitor all the appliances and sensor data in one environment.
