Comcast, the country's largest cable television company, has expanded its home automation and security product, adding a new feature that uses a "smart" thermostat to control your home's temperature.
In 2012 Comcast launched Xfinity Home, a service that can add home automation and security features through a monthly charge. They include motion sensors for doors and windows that if breached can alert the homeowner with a mobile phone notification or even call police through Comcast's central office. Customers also can install water sensors to detect flooding and webcams that can be viewed from a computer or mobile device. Xfinity Home also can control lights inside and outside the house as well as use smoke and carbon monoxide detectors.
Comcast has also included a smart thermostat to the package called "Eco Saver" that not only can be controlled remotely through a mobile app, but it also can automatically calculate how long it takes to warm up or cool down the home and manipulate the temperature the most efficient way.
