The existing Logitech Harmony replaced all your TV and AV remotes with a single controller.Logitech came to us because they wanted to extend their one-touch capability across the full range of smart home devices, including lights, thermostats, blinds, and locks—all via a new app. They also wanted to incorporate more complex trigger-based sequences, such as “turn off all lights, lower blinds, and lock all doors when I leave the house.” This required completely rethinking the interface to maximize clarity and simplicity—as well as establishing best-in-class control patterns for every category of smart device.
