Smart homes are homes that automate common household processes: * Lights turning on * Security Systems * Maintaining Environment * Temperature * Humidity * CO2 / VoCs ## What is the purpose of a Smart Home? When it gets down to it, everything that a smart home can do, a dumb home can do. There's an additional layer on top of flicking a light switch, the "data layer". This is the current state of the home. It's bi-directional. A light reports its status, but can also be controlled. Routines manipulate the data layer by reading state, and changing based on criteria. In other words, you translate processes into small programs that are run. A good example is my living room light. When I enter my living room, the motion sensor turns on the light. After 30m of inactivity in the room, lights turn off. # References
