LG webOS Binding

The binding integrates LG WebOS based smart TVs. This binding is an adoption of LG's Connect SDK library, which is no longer maintained and which was specific to Android.

Supported Things

LG webOS smart TVs

LG webOS based smart TVs are supported.

TV Settings

The TV must be connected to the same network as openHAB. Under network settings allow "LG CONNECT APPS" to connect.

Note: Under general settings allow mobile applications to turn on the TV, if this option is available. On newer models this setting may also be called "Mobile TV On > Turn On Via WiFi". In combination with the wake on LAN binding this will allow you to start the TV via openHAB. Please see demo.items and demo.rules example below.

Binding Configuration

The binding has only one configuration parameter, which is only required if the binding cannot automatically detect openHAB's local IP address:

Name Description
localIP This is the local IP of your openHAB host on the network. (Optional)

If LocalIP is not set, the binding will use openHAB's primary IP address, which may be configured under network settings.


TVs are auto discovered through SSDP in the local network. The binding broadcasts a search message via UDP on the network in order to discover and monitor availability of the TV.

Please note, that if you are running openHAB in a docker container you need to use macvlan or host networking for this binding to work.

Thing Configuration

WebOS TV has no configuration parameters. Please note that at least one channel must be bound to an item before the binding will make an attempt to connect and pair with the TV once that one is turned on.


Channel Type ID Item Type Description Read/Write
power Switch Current power setting. TV can only be powered off, not on. RW
mute Switch Current mute setting. RW
volume Dimmer Current volume setting. Setting and reporting absolute percent values only works when using internal speakers. When connected to an external amp, the volume should be controlled using increase and decrease commands. RW
channel String Current channel number. RW
channelName String Current channel name. R
toast String Displays a short message on the TV screen. See also rules section. W
mediaPlayer Player Media control player W
mediaStop Switch Media control stop W
appLauncher String Application ID of currently running application. This also allows to start applications on the TV by sending a specific Application ID to this channel. RW


Assuming your TV has device ID 3aab9eea-953b-4272-bdbd-f0cd0ecf4a46. By default this binding will create ThingIDs for discovery results with prefix lgwebos:WebOSTV: and the device ID. e.g. lgwebos:WebOSTV:3aab9eea-953b-4272-bdbd-f0cd0ecf4a46. Thus, you can find your TV's device ID by looking into discovery results in Paper UI.

You could also specify an alternate ThingID using a .things file, specifying the deviceId as a mandatory configuration parameter:

Thing lgwebos:WebOSTV:tv1 [ deviceId="3aab9eea-953b-4272-bdbd-f0cd0ecf4a46" ]

However, for the next steps of this example we will assumes you are using automatic discovery and the default ThingID.
