Who Knew?

Thanks to its motion sensors, the Nest knows to shut down your system when you’ve left the house, and to fire it up again when you come home. After about a week of adjusting it and learning your activity, it’ll understand your basic schedule and refine it with additional data over time. You can also adjust the Nest remotely using a web portal or iOS and Android apps — it uses custom real-time protocol to communicate with the Nest servers and make changes instantly.

So, no one is concerned about a Wi-Fi connected device which knows when you are out of the house?
