Best universal remotes for 2021 Cnet FacebookTwitterEmail 2of5 3of5 5of5 Logitech Harmony 650/665 Logitech Harmony wrote the book on the universal remote control devices and these are the most basic clickers we can recommend for a smart home. The main appeal over a cheaper, non-Harmony-based smart remote controller, or the device that comes with your set-top boxes, is the activity-based control. Press the “Watch TV” to use as a TV remote or “Listen to Music” buttons and the Logitech Harmony remote controller turns on all the relevant devices (such as your smart TV, Blu-ray player, and AV receiver), switches to the right inputs and maps the keys to that activity: volume to the receiver and channel up-down to the box, for example.
