Logitech Harmony remote control devices are regarded worldwide as the ne plus ultra in that space.
Which, undoubtedly, paints a target on the devices.
Whatever dethrones them would instantly be recognized as a winner, and take sales, market share, and profits, from Logitech.
It sure the specter of that keeps the wonks at Logitech up all night, and they strive to improve the devices.
Logitech even has a touch-screen device in the Harmony series called the Logitech Harmony Ultimate Home.
I have it here at The Ponderosa*.
The Harmony Ultimate Home now controls more than entertainment units: lights, locks, thermostats, and home control platforms are now in its repertoire.
I will download the iOS app, and go from there.
