homebridge-webos-tv

homebridge-webos-tv is a plugin for HomeBridge which allows you to control your webOS TV! It should work with all TVs that support webOS2 and newer. The idea is that the TV should be controlled completely from the native HomeKit iOS app and Siri, that is why volume appears as a light bulb or external input as a switch.

Features

  • HomeKit TV integration
  • HomeKit automation
  • Turn TV on / off
  • Mute / Unmute
  • Volume control (as light bulb, buttons or through iOS remote app)
  • Change sound output
  • Switch inputs
  • Open apps
  • Channel control
  • Media control
  • Show notifications
  • Emulate remote control
  • Run sequences of remote control button presses

To use the plugin iOS 12.2 or higher is recommended. If your iOS device is not running at least on iOS12.2 then you should use the legacy tv service.

Installation

If you are new to Homebridge, please first read the Homebridge documentation. If you are running on a Raspberry, you will find a tutorial in the homebridge-punt Wiki.

Install homebridge:

sudo npm install -g homebridge

Install homebridge-webos-tv:

sudo npm install -g homebridge-webos-tv

Troubleshooting

If you have any issues with the plugin or TV services then you can run homebridge in debug mode, which will provide some additional information. This might be useful for debugging issues.

Homebridge debug mode:

homebridge -D
