Logitech’s Harmony devices are wonderful universal remotes that allow users to control an entire suite of devices from one controller, or through a single app. The Harmony Link, released in 2011 allowed for just that. A puck-like device, it let users use their smartphones or tablets function as a universal remote. And next year, Logitech is remotely disabling them. In an email sent to users, Logitech says that in March 2018, Logitech Harmony Link devices will cease functioning.
