With the old Comcast/Xfinilty remotes for the boxes with a code tou could program them to with some button presses. I even got my Sony Suround Sound system to work wirh the Comcast remote. If I pressed power on with the Comcast remote the Cablebox, TV and Stereo would all turn on.With Logitech's Harmony remote, all I do is enter the model of TV in the app and it programs the remote to access the smart features. This remote is on it's third TV and has yet to meat a function it couldn't handle.
I just got X1 cableboxes that don't have a clock and haven't tried linking them though. I still have my Sony remote so why bother?
