lgcommander.py

lgcommander.py is a Python script for controlling your Smart Lg TV with your PC. It can be used for gaining access to hidden menus and modes.

Supported models

Lg has released two TV remote control apps for android smartphones in Google Play app store; each with a list of supported models. One for 2012 models and the other for some earlier models. If your TV is not on those lists, it may not be controllable through a network connection and this script may not work for you.

Requirements

A PC, with Python 3.x installed, connected to the same network as your Lg TV.

Usage

See the available options with: ./lgcommander.py --help or python3 lgcommander.py --help

usage: lgcommander.py [-h] [-V] [-H HOST] [-p PORT] [-P {roap,hdcp}]
                      [-k PAIRING_KEY] [-c COMMAND]

Control your Smart Lg TV with your PC

optional arguments:
  -h, --help            show this help message and exit
  -V, --version         show program's version number and exit
  -H HOST, --host HOST  IP address or FQDN of device. Use the special value
                        "scan" for a multicast request for TVs in your LAN.
                        "scan" will also be used if this parameter was
                        omitted.
  -p PORT, --port PORT  TCP port (default is 8080).
  -P {roap,hdcp}, --protocol {roap,hdcp}
                        Protocol to use. Currently ROAP and HDCP are
                        supported. Default is to auto detect the correct one.
  -k PAIRING_KEY, --pairing-key PAIRING_KEY
                        Pairing key of your TV. This key is shown on request
                        on the screen and does only change if you factory
                        reset your TV.
  -c COMMAND, --command COMMAND
                        Send just a single command and exit.

Some useful codes:

• for EZ_ADJUST menu enter 255
• for IN START menu enter 251
• for Installation menu enter 207
• for POWER_ONLY mode enter 254

Warning: Do not enter 254 if you do not know what POWER_ONLY mode is. You can find additional information about menus and modes here: http://openlgtv.org.ru

Problem with latest LG firmware:

If you upgrade your TV firmware to 05.12.05 or later, "Tool Option 3" may be greyed out and you may not be able to make changes. Please e-mail me if you have a solution to this problem (other than not upgrading).

Thanks for LG Commander! I've just managed to sort out the Options3 greyed out issue. Follow the instructions here: http://www.avforums.com/forums/lg-forum/1651400-official-lg-lw550t-3d-led-thread-part-9-a.html

Windows users:

You can avoid the black console window if you change the "py" file extension to "pyw".

Newer LG Smart TV (year 2012) models:

Benke Tamás:

I wanted to use your lgcommander script, but I realized that its not working with lg 2012 smart tv series. I made some changes, now its working with the new series, but lg changed the keycodes too. Now, there are keycodes above 255 and ez-adjust, in-start code changed too, but I dont know them yet. I attached my version, if you want to improve yours.

• Benke's version of the script was added as lg_2012_commander.py.
• ypid combined the script into lgcommander.py (use ./lgcommander.py -P roap).

Ajay Ramaswamy:

Hi,

Thanks for your lgcommander script. I was playing around with my 2012 55LM6200 TV and LG has provided a Android App Smart TV which provides a remote control app.

I ran that app thru unzip, dex2class and JD-GUI and found the file com/lge/tv/remoteapps/Base/RemoteKeyIndex.class contains these key mappings

    KEY_IDX_3D=400;
    KEY_IDX_ARROW_DOWN=2;
    KEY_IDX_ARROW_LEFT=3;
    KEY_IDX_ARROW_RIGHT=4;
    KEY_IDX_ARROW_UP=1;
    KEY_IDX_BACK=23;
    KEY_IDX_BLUE=29;
    KEY_IDX_BTN_1=5;
    KEY_IDX_BTN_2=6;
    KEY_IDX_BTN_3=7;
    KEY_IDX_BTN_4=8;
    KEY_IDX_CH_DOWN=28;
    KEY_IDX_CH_UP=27;
    KEY_IDX_ENTER=20;
    KEY_IDX_EXIT=412;
    KEY_IDX_EXTERNAL_INPUT=47;
    KEY_IDX_GREEN=30;
    KEY_IDX_HOME=21;
    KEY_IDX_MUTE=26;
    KEY_IDX_MYAPPS=417;
    KEY_IDX_NETCAST=408;
    KEY_IDX_PAUSE=34;
    KEY_IDX_PLAY=33;
    KEY_IDX_POWER_OFF=1;
    KEY_IDX_PREV_CHANNEL=403;
    KEY_IDX_RED=31;
    KEY_IDX_STOP=35;
    KEY_IDX_VOL_DOWN=25;
    KEY_IDX_VOL_UP=24;
    KEY_IDX_YELLOW=32;

I have tried all these codes on my TV and they work OK

I hope you find this useful and someone else can test and confirm, and speed up the search for the Service Menu codes.

Thanks & best regards

Ajay
