I try using this code to turn on my LG uq8050 tv but i cant turn on. But able ti turn off. Also i connect this to my home assistant. But unable to use google nest hub 2 to co trol it. Please help me with this thanks.
Turn on use a “magic packet” sent over the network, but the TV is only able to receive it on the LAN connection.
I can’t see your connection type in your post though, so it was just a guess to a cause. 
Thank yòu for ur reply @WallyR
Currently i using wifi in my tv. So shud i use lan wire then i can use is it.
Is there anyway to turn on if only my wifi is connected.
this works also on Wifi, for me it does,
but you need add an automation like this
- alias: Turn On Living Room TV with WakeOnLan
trigger:
- platform: webostv.turn_on
entity_id: media_player.living_room_tv
action:
- service: wake_on_lan.send_magic_packet
data:
mac: <tv amc address>
id: <automation id>
check the docs
edit:
and if you have it working, check this one
Thank you @bkbartk. I will try this method later. But may i ask what is automation id here. Kinda new to HA. Thanks again.
I think you don’t need the id,
it’s an autogenerated value by HA
but it’s in my automation. that’s why I copied it.
The example doesn’t have it.
using wired myself, so it does not apply to me, but I remember vaguely there was something with a power-save/deep-sleep setting involved in using WiFi with WakeOnLAN
