Solved

[pitrus]

May I ask how you solved this one? Will it work with older non webos-based smart-TVs from LG?

[dennisaion]

Sure. This is what I did. And it works for pre-WebOS models.
Particular script I use is for models released in 2011. Also have script for 2012 models.

In configuration.yaml add

Until someone works the script into a component I’ll keep using this and add shell commands for volume , channel changing, etc.

Turning TV on and off via HASS was what I needed.

Hi

My LG TV is a 2011 model too and I’m trying to make it work with homeassistant. I’d like to use your config, but the forum page messed with your copy/paste. May you attach the original files? Or upload them to some place? Thank you!

[surge919]

Continuing the discussion from [WORKAROUND] LG TV Remote:

Are you in the US?

I have an LG LW5600 and from what I’ve read, there is an alternate firmware which only applies to European models.

http://openlgtv.org.ru/wiki/index.php/Achievements

I’ve tried to telnet to my TV on port 1900 as shown in the script but the TV doesn’t respond.

[dennisaion]

Wow. Okay will do it again.

If the LG remote apk works for you (the 2011 supporting one) then the script will work for you as well.

[dez (Anton Shtopany)]

anyone get this script work with 2013 models? mine respond “Unauthorized” to pairing request:

thanks, this one works for me

[dennisaion]

You’re welcome

[enricfp1 (E)]

Has anyone gotten this to work with a WebOS 2014 model?

[surge919]

Not sure what’s included and it doesn’t specify the year, but there are separate steps for LG WebOS

Media Player might have power options

LG webOS Smart TV

LG webOS Smart TV

[enricfp1 (E)]

I’ve set both of those up but no power on option. It’s just pause/play but it can turn it off. I’d like to remotely be able to turn it on though. I was thinking something to do with wake on LAN?

[thundergreen]

hi all… i followed this manual but unfortunately nothing works with it… how could i figure out whats wrong ? I have a 2011 model and remote apk works pretty good on my phone.

[Pilot]

Yes, you need to use wake on lan to power on a Web OS tv. Make sure you enable waking the tv in the settings menu of the tv.

You could solve this without shell scripts with the native wake_on_lan component of homeassistant. I did the following:

1. Define a media player for the webos tv. This will allow you to get the state of the tv and turn it off.
2. Define a switch which updates itself with the current power state of the tv: tv_switch. Use this to turn the tv on or off. E.g. expose it to homebridge as ‘TV’ if you want to control the tv with Siri.
3. Define a (hidden) switch to send the wake-on-lan packet when the tv_switch is turned on.

To switch sources, use the media_player.select_source service.

Btw, I haven’t figured out is how to detect when the tv is off but recording.

Switches config:

- platform: template
  switches:
    tv_switch:
      friendly_name: TV
      value_template: '{{ states.media_player.lg_webos_smart_tv.state != "off" }}'
      turn_on:
        service: switch.turn_on
        entity_id: switch.wol_lg_tv_eth
      turn_off:
        service: media_player.turn_off
        entity_id: media_player.lg_webos_smart_tv
      entity_id: media_player.lg_webos_smart_tv

- platform: wake_on_lan
  name: wol_lg_tv_eth
  mac_address: '00-08-00-00-00-00'
  host: 192.168.1.123 #Irrelevant, will monitor the state of host to set the switch state.
  turn_off:
    service: switch.turn_off
    entity_id: switch.tv_switch

[dennisaion]

Hello there the stuff written on top is for 2011 and 2012 models. Basically pre 2012 models.
As they don’t have WOL you would have to wake your TV via connected device like Bluray player that supports LAN (for WOL.)

You then wake the Bluray player that in turns wakes the TV through Simlink.

Then you can use the above work around to chance channels turn volume up and down or turn it off.
I posted more key commands here

Support for pre 2012 models LG Nestcast TV's needed

The commands you seek are these: Supported Models Information LCD/LED TV LZ9800, LZ970*, LZ9700, LZ9600\nLW9600, LW950*, LW9500, LW770*, LW7700, LW7500, \nLW650*, LW6500, LW570*, LW5700, LW5600, LW550*, LW5500\nLV570*, LV5700, LV550W, LV550T, LV5500(except size 26&apos;&apos;, 22&apos;&apos;, and Hong Kong), LV5400\nLV375*, LV373S, LV372S, LV3700\n\nNorth America Only \nLK550, LK530\n\n\n- PDP TV\nKorea, Australia, New Zealand, Asia\nPZ950, PZ570\n\nCentral Asia\nPZ950\n\nNorth America\nPZ950…

Did you created the tv.py to be called?
