LG Netcast apps

Configuration
1

So I’ve managed to connect my LG Smart TV (Netcast - 400ub800v) to home assistant, I can change channel and volume, but I can’t get it to turn the TV on, nor can I figure out how to get it to launch youtube/Netflix/Plex.

Is this even possible on this TV or do I need to upgrade my TV finally?

Is your LG TV connected wired or wirelessly? If you can, try connecting the TV with an ethernet cable and see if it’s possible to turn on/off the TV using Home Assistant.

Double-check the instructions and make sure your TV’s power settings are correct and you’ve enabled all necessary settings.

I’m using a LG netcast tv too. Turn off works good but there’s no turn on possible (WiFi and lan interfaces are shutdown completely when tv is off).
And about applications I did not see any options to do this from the netcast python lib. Sorry !

I’m using three-year-old and one-year-old LG WebOS-based televisions. Here is my configuration YAML for reference:

media_player:
  - platform: webostv
    host: 192.168.1.98
    name: Living Room TV
    filename: webosLRtv.conf
    turn_on_action:
      service: wake_on_lan.send_magic_packet
      data:
        mac: "xx:yy:zz:aa:bb:cc"

Webos is very different from netcast. I also tried the wake on lan on lg netcast but that’s not working !

hey guys,

I have the same scenario and I managed to do this in this way (It’s a little tricky ).

I have a RPI with Kodi in that TV and the RPI is always on ( not only when the TV is on ). If you have it connected via HDMI. so I saw that if I send a command to reproduce a video in the RPI, the RPI sends a command to the TV to turn on.

So, what I have is that when I want to turn on the TV, I just send a 5 seconds YouTube video to play in Kodi, this fires the TV on :slight_smile:

for me it works … not the best solution, but it works.

Or use an IR blaster. Cost is about 10€.
I have a similar Netcast TV and had the same problem. When these TVs are off, only IR is working. No LAN, no WiFi so you cannot wake on lan it. The next problem I had was the media player wasn’t Simplink enabled(HDMI-CEC) so I could turn on the TV from Hass with HDMI-CEC but couldn’t switch to the media player channel.
Installed a broadlink IR mini and all is good. Just turns the tv on and then I can use the Netcast state to see if the TV is actually on.

Anyone stumbling on this might consider HDMI CEC from another device to wake the old LG tv

CECActivate in Kodi seems to wake my LG but there are other issues, resorting to sending a UDP packet to trigger this…
