lg_2012_commander and multiple screens about lgcommander HOT 15 CLOSED

When I wrote the script I assumed there would be only one LGtv. It may not function properly if more thant one LGtvs are active.

Try my fork of lgcommander and give it the parameters --host and --pairing-key.

Hi ubaransel, I can confirm that is the case. I've just been testing this quite intensively from the windows command line - sending the same command repeatedly and noting what happens.
Sure enough, now and again the command will hit the right screen and then I don't get prompted for the pairing key. Dissappointingly though, I do still get prompted for the command number despite including -c 20 at the end of the command.

Something else I noticed is that if I wait for the pairing key on the TV screen to time out and then OK the blank prompt on the PC, it will still let me send a command to the screen that the pairing key appeared on (if you follow). This got me to thinking that perhaps the pairing key is superfluous if communicating over the LAN. Perhaps the screens could be targeted more directly using the ip address?

My version doesn't have command line options. Are you using ypid fork?

read his comment above I think he is online.

I'm running python from the Windows command line and telling it run the lg_2012_commander script like so...

C:>python c:\lgtv_IB1.pyw -c 20

...where lgtv_IB1.pyw is a copy of lg_2012_commander.py containing the pairingkey of screen 1 in the office.

Try this https://github.com/ypid/lgcommander/archive/master.zip
and then use python c:\lgcommander.py --host %ip_of_your_tv% --pairing-key %key_of_your_tv%.

Kuhal can you see Robin Schneider (ypid) comments? you are using his version. Talk to him.

Hi ypid,

Ah! are those %% significant?

from lgcommander.

No, this is a variable for cmd as far as I know. So for example use python c:\lgcommander.py --host 192.168.2.8 --pairing-key DDGWAF

Okay thanks - just fetching your script now - will let you know how I get on.

No dice - same problem. The DEBUG message says "No valid pairing key from user. Asking user \u2026". Our IT guy's gone home but I get the impression the splitter that sits between the PC and the TV screens polls the screens one after the other and the python script command only gets sent randomly to one screen. I either need to work out a way to tell the splitter which TV to send the command to or I need the script to loop until it gets a positive response.

DOH!!
I do apologise ypid - it DOES work - I managed to miskey the IP address in my command line test. I just need to create the vbscript now and get Windows scheduler to do the rest. :)

Thanks guys, for your help with this otherwise intractable problem.
I'm not sure if this is the right place or the right way to post this but I thought I'd make my VBscript available, since I know others have had the same issue as me, with their LG screens turning off 2 hours after automatic turn on...

Nice that it works for you. You can open a pull request against my fork with this script an I will include it. I don’t know VBscript myself. Maybe you can remove the redundant definition of IP1 and so on and instead use comments for arrTV(0,0) =. Can you make it more generic by using the array length in For i = 0 to 5 instead of using a fixed value?
