Comcast is looking to turn Xfinity broadband into a kind of “home operating system,” bringing home-automation controls for hundreds of devices to Xfinity Internet customers at no extra cost. The goal, for Comcast, is to get embedded into customers’ homes through the different IoT devices and provide useful features so they’ll be less likely to switch providers. Comcast offers home-automation features already with its Xfinity Home security service, but what’s different with the new program is that Comcast is decoupling automation from security. The new Xfinity IoT features will be launching with third-party devices toward the end of the first quarter of 2018.
