Logitech recently informed customers that it will be discontinuing service for its popular Harmony Link remote system
, which allows users to control home theater and sound equipment from a mobile app. "Customers received an email explaining that Logitech will 'discontinue service and support' for the Harmony Link as of March 16, 2018, adding that Harmony Link devices 'will no longer function after this date,'" reports Ars Technica. From the report: While Logitech is offering a one-time, 35-percent discount on its Harmony Hub to affected customers that are out of warranty, that's not enough for Harmony Link users who are expressing their dissatisfaction on Logitech support forums and Reddit. Users have not experienced major problems with the Harmony Link system that would indicate they are approaching end of life. Harmony Link customers do not pay a subscription or service fee to use the device, either. The only reason provided comes from a Logitech employee with the username Logi_WillWong, who explains in a response post from September 8, 2017 that Logitech will not be renewing a "technology certificate license" that expires in March. No details were provided about how this certificate license allows the Harmony Link to function, but it appears that without it, those devices will not work as promised. "The certificate will not be renewed as we are focusing resources on our current app-based remote, the Harmony Hub," Logi_WillWong added, which seems to indicate that the shutting down of the Harmony Link system is a way to get more customers on the newer Harmony Hub system.
