Logitech Harmony is a line of universal remote controls created by Logitech. These remotes are designed to control multiple devices, such as TVs, cable boxes, and gaming consoles, with a single device. They can also be configured to control smart home devices such as lights and thermostats. The Harmony remotes use infrared (IR) signals to communicate with devices, and can be configured using a computer or mobile device. Logitech Harmony Elite is a high-end version of the remote that comes with a hub that allows control of smart home devices via Wi-Fi or Bluetooth.
