openHAB

LG webOS Binding

The binding integrates LG WebOS based smart TVs. This binding uses a forked version of LG's Connect SDK library.

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. In combination with the wake on LAN binding this will allow you to start the TV via openHAB.

Discovery

TVs are auto discovered through SSDP in the local network. The binding broadcasts a search message via UDP on the network.

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.

Channels

Channel Type ID Item Type Description Read/Write
