WebOS TV Integration will only Wake On Lan via WiFi, no longer via Ethernet

[DrewXT]

The problem

when the WebOS TV integration was migrated from configuration.yaml configuration to the UI, Power On via Media Player broke - this is well documented, as are a couple of fixes, including a BluePrint to create an automation to resolve the matter.

I've also seen that Wake On Lan no longer works from HA to WebOS when hard wired, which it did before the migration to the UI configured Integration. I've proven this to be the case through trial and error, with a hard wired TV being exceptionally hit and miss to get to turn on via WoL, and being consistent using a Wireless connection.

What version of Home Assistant Core has the issue?

core-2022.3.5

What was the last working version of Home Assistant Core?

core-2021.12.1

What type of installation are you running?

Home Assistant Supervised

Integration causing the issue

LG WebOS Smart TV

Diagnostics information

TV is an LG G1, which doesn't capture logs during the WoL process, because it's turned off.

Firmware release on the TV is 03.21.10, which is around 1 month since release

the HA logs are in the logs area

Example YAML snippet

alias: Turn on TV
description: ''
trigger:
  - platform: webostv.turn_on
    entity_id: media_player.living_room_tv
action:
  - service: wake_on_lan.send_magic_packet
    data:
      mac: re:da:ct:ed:ma:c#
mode: single

Anything in the logs that might be useful for us?

Logger: homeassistant.components.webostv.media_player
Source: components/webostv/media_player.py:113
Integration: LG webOS Smart TV (documentation, issues)
First occurred: 10:56:00 AM (1 occurrences)
Last logged: 10:56:00 AM

Error calling async_select_source on entity media_player.living_room_tv, state:off, error: WebOsTvCommandError("Not connected, can't execute command.")

unfortunately this is the only error being seen in the logs - my HA is running the current release build, in a fully supported Supervised configuration.

Hey there @bendavid, @thecode, mind taking a look at this issue as it has been labeled with an integration (webostv) you are listed as a code owner for? Thanks!

I think I may have identified the root cause of this, which should only require a documentation update.

At some stage, LG have implemented by default a function called Quick Start+, which puts the TV into a standby mode, however the TV doesn't seem to have WoL enabled by default via the physical interface. Turning this function off re-enables WoL via the physical connection.

It works beautifully using wakeonlan from a Linux server, but not consistently via HA…

To turn OFF Quick Start+, follow the LG Menu (this is relevant to a G1)
Settings → All Settings → General → Devices → TV Management

[ianfretwell]

I suspect this might be specific to the WebOS version - you appear to have a G1 and therefore WebOS 6 ?

I have three models of LG running WebOS 3.5/4/4.5 - all hard-wired, all with QuickStart+ enabled - and all appear to power-on just fine via HA. Maybe I haven't done enough testing as its not a feature I use a lot anyway but it's never failed yet.

[DrewXT]

our firmware is on 3.21.10 and it's an OLED55G1PTA

[ianfretwell]

Sure - but the firmware version has absolutely nothing to do with the webos version. You'll find there are separate entries for each in the 'About this TV' menus somewhere.

You'll probably end up with a firmware version of 5.x or 6.x by the time a couple more years have passed. But you'll still only have a nominal WebOS version of 6.0 - that's just the way LG does things.

I have 4 of the 43UN7000PUB in my house, and I have the ability to hard wire them all which I prefer for performance with Plex, Netflix, etc. but I found the same behavior that WOL basically doesn't work but works fine with WiFi. Not a major issue, but considering LG allows one network connection this is problematic.

ah yeah - found it - 6.2.033 (kisscurl-kavir)

Not a major issue, but considering LG allows one network connection this is problematic.

exactly the reason why I like mine hard wired. I'm actually wondering if it's something more basic than the Integration. I have a template switch and regular WoL Automation that calls WoL against the Ethernet MAC, and they work 100% of the time, yet when being called via webos.turn_on it doesn't work reliably.

Template Switch that works is this:

- platform: template
  switches:
    living_room_tv:
      value_template: "{{ is_state('media_player.living_room_tv', 'on') }}"
      turn_on:
        service: wake_on_lan.send_magic_packet
        data:
            broadcast_address: 192.168.0.255
            mac: B4:B2:91:70:C0:2A
      turn_off:
        service: media_player.turn_off
        entity_id: media_player.living_room_tv

yet when calling it via this automation, which should trigger from the power button on Mini Media Player, it doesn't work reliably, nor will it call via any other mechanism (including directly running the automation)

alias: Turn on TV via Template Switch
description: ''
trigger:
  - platform: webostv.turn_on
    entity_id: media_player.living_room_tv
condition: []
action:
  - service: switch.turn_on
    data: {}
    target:
      entity_id: switch.living_room_tv
mode: single

I am, however - not smart enough to be able to look into the code of the Integration to work out what it's doing :(

[host-felice]

Not sure if it will work for you too, but manually writing the automation to wake up my TV didn't work. I made the automation with the user interface and selected the "Device is requested to turn on" automation. Now it works again with the WOL over ethernet.

Hi Guys,
I have the same problem.
I'm using mini-media-player to use the TV and I find it quite usefull to just turn on the TV, and switch to spotify for example.
Then I can control spotify from my laptop. It's really convenient when I don't have the remote control at hand, but am remote working with my laptop.
Since few weeks, I cannot turn on my TV anymore. I don't know exactly when it happens. But it's really annoying.
I have the exact same error message than DrewXT:
2022-03-04 15:28:26 WARNING (MainThread) [homeassistant.components.webostv.media_player] Error calling async_select_source on entity media_player.tv_salon_2, state:off, error: CancelledError()

I have turned ON QuickStart+, I am using ethernet because wifi not reliable for Plex..
Here is the configuration I have in configuration.yaml:

webostv:
  host: 192.168.1.40
  name: TV Salon
  turn_on_action:
    service: wake_on_lan.send_magic_packet
    data:
      mac: A8-23-FE-D6-XX-XX
      broadcast_address: 192.168.1.255

Can anyone help me please ?

Have a look at this (things changed with 2022.2):-

Thanks, @ianfretwell.
If I understand, I must use an automation to turn on the TV?
I can't use "mini-media-player" like I did until now? That would be bad to have a separate button to turn on the TV..
Thanks anyway for your help!
