The Logitech Harmony Link eliminates the need to dig under couch cushions for various remotes. The gadget connects to your home Wi-Fi network and pairs with a free app for your iOS device or Android phone to control your TV, set-top boxes and other home entertainment gear. If you want to switch from listening to music to watching a movie, for example, the Harmony Link takes care of changing the input. The device also connects to your TV service provider’s channel guide to help you find something good to watch.
