"Think about it:
With IFTTT, you can build an efficient smart home that can respond to each and every cue. You can activate the NEST thermostat prior to your estimated arrival time, while another applet can activate the fan should there be too much smoke in the kitchen. You can receive notifications when motion is detected, or a particular family member has opened the front door."
“...smart home products can automate certain tasks and remove many of the unnecessary or mundane aspects of life at home. What’s more, home automation can improve the quality of life, while connecting these devices to each other and simplifying how we live in the process."
