Hello.

pi@raspberrypi:~/lgcommander $ ./lgcommander.py
Lg TV not found

pi@raspberrypi:~/lgcommander $ ./lgcommander.py
Network error

pi@raspberrypi:~/lgcommander $ ./lgcommander.py

_tkinter.TclError: no display name and no $DISPLAY environment variable

In our office we have a Windows 7 PC dedicated to running a live MI reporting presentation on 5 LG screens (model: 47LN578V). Having obtained the pairing key for each screen I created 5 copies of lg_2012_commander.py, renamed as lgtv_IB1.pyw, lgtv_IB2.pyw etc. and hard-coded the pairing key for a different screen within each file.
My understanding was that this would then bypass the script's pairing key prompt and let me automatically send commands to the screens via vbscript.
Testing this from the command prompt, however, it either returns "Lg TV not found" or I get a dialog prompting to "Please enter the pairing key you see on your TV screen".
The screen that the displayed pairing key appears on seems to be random (remember there are 5 screens connected to the same LAN). And, I think, herein lies the problem.
I think perhaps the command sent from the script only hits one screen - invariably the wrong one - and so it resorts to the prompt.
Is there a clever python programmer out there who could write a loop to keep sending the hard-coded pairing key until it hits the right screen or fails after a certain number of attempts?

Hi,

I tried to execute 255 and 251 but it returns nothing... My tv is LG LA6200 thanks

This is the error I get. What the problem can be??? Libraries are uploaded and included.

Hi

Have you thought putting the project under a license? I did not find any … I personally would go for AGPLv3. Is that OK with you?

Hello
I do not know what is causing that but sometimes the script is not working
I am running it on Pi3 on LG 2012

I'm using the script to try to connect to an LG TV running WebOS, the script shows it has found the device and displays the correct IP address but then says 'Connection refused'. (see below)

DEBUG: Found device: ('10.0.1.7', 47680)
INFO: Using device: 10.0.1.7
DEBUG: Detecting accepted protocol.
DEBUG: Testing protocol: roap
[Errno 61] Connection refused

The is no pop-up on the television notifying of a pairing code.

Any ideas? Thanks

Hello, does anyone find out what is the keycode for enabling In Start menu on LG's 2012?

i always get the following error: could someone please help?

its an lg lw5500 tv

Hi! This is not really an issue, sorry for that.
I tried the python script an it works great! Thanks for sharing.

I'm trying to connect to my TV making direct HTTP POST calls. Could you help me out telling me how to make those calls directly from a web browser?

Thanks a lot!
