git clone https://github.com/cali-95/LGTVLinuxCompanion.git
python -m venv my_venv
source my_venv/bin/activate
pip install -r requirements.txt
run python lg_tv_linux_companion.py -c turnOffScreen -k wrong_key -t <ip> with your ip and conform the popup on your tv.
take note of the client key in the log file ~/lg-companion/log.txt
run the same commend with the right client-key, your lg tv should go black, active it again by pressing some button on the remote
find other options with python lg_tv_linux_companion.py -h

Automatic (use triggers)

thanks @fulalas for the suggestion

perform the steps unter manually and then the following ones

install acpid and enable it sudo systemctl enable acpid
create a file called client-key with your client key: echo -n "to_be_replaced" > client_key
echo -n "to_be_replaced" > ip
sed -e "s#the_user#$(whoami)#g" -e "s#the_dir#$(pwd)#g" monitor_on.dist > monitor_on
sed -e "s#the_user#$(whoami)#g" -e "s#the_dir#$(pwd)#g" monitor_off.dist > monitor_off
chmod +x monitor_on && chmod +x monitor_off
sudo mv monitor_{on,off} /etc/acpi/events/
sed -e "s#the_dir#$(pwd)#g" run_in_venv.sh.dist > run_in_venv.sh
chmod +x run_in_venv.sh
reboot
enjoy

Troubleshooting

the trigger is not triggered

run acpi_listen to find the right acpi event and change it in the monitor_(on|off) files

change to the monitor_(on|off) files are not activ

a reboot is required
