Customers demanding home control via HDTVs might be interested in the Logitech Harmony for Google TV-- since the latest version allows one to do exactly that in conjunction with the Harmony devices.
The app features a grid-based UI and provides quick control of connected devices such as smart lights, blinds and thermostats, all without need to interrupt current viewing. Such functionality requires a Harmony hub-based remote installed on the same network, such as the Elite or the Hub.
