A “smart home” is one in which various devices are interconnected to work together, giving the residents the ability to control the gadgets individually or collectively. It is that “collective” control where it gets interesting.
Imagine you’re going home. You’re about to make that turn into your neighborhood, and the home “senses” your approach and sets up things just the way you like them. The garage door opens, the thermostat adjusts from it’s “vacant-house” temperature to a more comfortable setting, the lights turn on, and Alexa boots up your favorite mix of tunes. You don’t even have to do anything to make all of this happen. It’s been pre-configured for you – BY you – and all you have to do is show up.
How does it work? Your smart phone’s location is read by a “geo-services” program that triggers the smart devices in your home.
It works in reverse too. Geo-services sees that you’re leaving for the day and makes the appropriate settings to shut down, and lock up. No more worrying about whether you locked the door or turned off the lights.
