  • Issue of the topic: I hav link my LG samrt TV using LG webOS Binding successfylly.
    9 channels are linked and i can control my TV using Classic UI & HAB pane.

i want to control my tv using alexa & Basic UI using whic i control all smart switches of my house.

i have created .items files and using .sitemap file i expose items on android app and BASIC UI.

i dont know how do in link items with LGTV binding items and expose them to Alexa and display on BASIC ui.

snap of LG Webos buinding items in paper ui as below.

Paper UI items
Paper UI items1366×768 92.3 KB

however i created items for power , Mute & Volume for tv as below.
.Items file is as below.

Switch TV_Power1 “TV_POWER” (GF_LivingRoom_TV) ga=“Switch”,alexa=“PowerController.powerState”}
Dimmer TV_volume1 “TV_Volume” (GF_LivingRoom_TV) {ga=“Light” ,alexa=“Speaker.volume”}

.rules file is as below.

rule “TV_POWER”
when Item TV_Power1 changed
then
if(TV_Power1.state == ON){
lgwebos_WebOSTV_d0e611a2_d6a1_feeb_ffe2_e9b507edfcf7_power.postUpdate(ON)
}
if(TV_Power1.state == OFF){
lgwebos_WebOSTV_d0e611a2_d6a1_feeb_ffe2_e9b507edfcf7_power.postUpdate(OFF)
}
end

by doing this i get updates on openhab log viewer , classic ui & BASIC UI during applying any command but tv didnt follow any commands.
logviewar message is as below.

Create your LG items in files and copy the channel info from PaperUI and configure it how you like.

Example:

Switch FrontPorch_Light "Front Porch Lights" <light>  ["Lighting"]  { channel="mqtt:topic:pibroker:sonoff-7CB10D:power" }

Just paste in the channel info like above.

By following openhab Lgwebos binding documentation I understand how to link switch items.
