Smart Phone, Smart Home: With a wireless device, you can control your house from afar

摘要

PEOPLE HAVE TALKED FOR decades about using high-tech gear to create smart homes. But until recently, installing the equipment could cost tens of thousands of dollars and often involved unsightly wires. Now, however, you can use wireless technology to duplicate many useful smart-home features for a few hundred bucks. Most wireless systems will let you use a smart phone or tablet to perform tasks remotely, such as adjusting your thermostat, turning lights on and off, and controlling a basic security system. Pricier systems add such features as moisture detectors and remote door locks.
