LG TV IP control

Hello,

Did anyone manage the app to work with IP on Lg Tv?
I found some info here:
https://github.com/ubaransel/lgcomman...
but I don't know how to implement it into iRule

  • Hey Attila,

    We do not have an LG TV that is IP controllable in the office. If you want I can work with you to try and decipher the protocol.

    At first glance it looks like you need a "key" from your LG tv, which shouldn't be to much of a problem, but it also appears to create a "session". Meaning you do some form of handshake every time you want to control the TV. This can be a problem for iRule, but we won't know until we try :)

    Email me at alex.boyd@iruleathome.com if you want to work together to figure these commands out.

  • LG TV's offer IP control, but there is no POWER ON or any way to wake the TV up. So the IP control is not complete in the sense that you would have ot use IR to turn the TV on.

    I believe there is some Sharp models that offer IP control through iRule. As far as specific models, I can't really comment.

    Maybe take a look at this thread. There is some knowledge that you should know if your looking for IP controllable TV's

    Is there a list of IP controllable TVs

  • Alex:

    Are the firmwares for LG tvs are open source?? It seems they list them on the LG website. If that's the case, would there be a way to enable WOL for LG tvs? I have two 47LS4600 LG tvs and it would be great if they could do WOL without having to use IR blasters out of an itach device.

    Any updates here for LG support would be most welcome. Cheers!

  • Hey Guys,

    I just spent a little time on this topic. And actually LG is not supporting any" Power On" command via IP.
    The only way for 2011 models that they have a serial port, and through this you can do anything.
    As far as I know RS232 port was removed from 2102 models :(
    Just a short note: I have an LW5500 model, and with the Android version on LG "stock" remote it is also impossible to turn on the TV.

    Cheers,
    Attila

  • Any further updates on this? I can confirm that 2013 LG 55LM9600 do not have an RS232 port on them. I am hoping that they can be controlled through IP?

  • They certainly can be controlled through IP. I'm currently controlling my 55LM8600 with IP control via my Redeye unit. However, as mentioned earlier, they don't support Power On via IP, so for that aspect, I have to use an IP-to-IR device (Redeye, GC, etc), or HDMI-CEC power on via my receiver.

    If neither of those solutions work for you, you'd have to use a physical remote to turn the TV on, which from my understanding in another thread, is why the iRule team decided not to program support for it in. Why LG decided to go that route is beyond me, particularly since it's running a Linux kernel and I'd suspect the ethernet hardware could have easily had it's driver compiled with Wake-on-Lan support enabled.

    The control mechanism itself isn't actually all that complex, since it uses HTTP GET and POST methods for communicating between clients and the TV. The current reason you can't control it directly from iRule is that you can't modify the User-Agent string in iRule, while LG has mandated the use of a very specific non-standard User-Agent string per their control API.
    • Most of what you said is true, although the last paragraph is a little off. Overriding the header of an HTTP GET or POST can be done (only internally at this point), but that isn't what LG TV's require. They use a session token which isn't exactly the same, it's used to identify currently connected controllers I assume. Unfortunately, that makes things more difficult :( . It would require it's own "special" gateway, unless the protocol has changed from 2012 to 2013.

      I haven't actually tested the above, but I looked through the code from the link

      I read a post somewhere that LG was to support POWER ON in the future when they drop the RS232 port, which it appears they have. Best way to find out is to download the LG app on your phone and see what functionality exists. Maybe someone can report on this and we can look into it a bit more.
    • Sorry, I meant the final sentence to be a "you the end-user can't currently do this with iRule alone" statement, not an overriding "it can't be done" statement, particularly when talking to one of iRule's software engineer's. Apologies if I wasn't clear about that.

      I actually have tested all of this. I have complete(-ish) control via their IP protocol working with my 55LM8600--without using their app (which, as an aside, actually differs in some minor ways from their UDAP 2.0 specifications found in the SmartTV library's reference section). Unless I'm totally oblivious, which is sadly plausible, *I* currently can't do this using iRule alone though you undoubtedly can, but I did so with the Redeye before moving to iRule. The session token in question is a 6 digit number which generates on screen when you send the correctly formatted xml body inside of a certain POST command to the TV (true of the official Android App and likely the iOS App as well). However, without changing the User-Agent string correctly, you won't be able even get it to show the session token in the first place. Both are required.

      I can post exactly what is needed to help you guys out if you think it's worthwhile to add despite the Power On limitation. I'll also add that you'll possibly have to modify how your gateway setup works as well, since one has to use both GET and POST commands for the full benefits of IP control for these TVs (most commands use POST, but status queries for volume/mute, 3D, channels, etc use GET commands) and the android iRule app at least limits me to one or the other.

      Oh, and as for LG's own app, no, even it can't currently be used to power on. Deleted from 3 different android devices, then reinstalled tonight (to make sure I had the latest official release), and tried. No power on function available yet.

  • Okay ... I have my setup currently working well using baluns to control my LG tvs out of my iTach for power on/off.

    Is there any way to send the other signals over IP?? I am having some latency delay over the IR, so I'm hoping I can diminish the latency by sending my other signals over IP. Is this possible with the 2012/13 LG tvs in iRule? Anyone know how I should establish the gateway for the non-RS232 LG sets?

    Thanks folks!

  • Eric,

    No, currently with iRule alone, we end users cannot control the LG 2012/13 SmartTV sets via IP control (see the previous post I made and comments). There are ways around this, but they generally require extra hardware and custom programming to get working.

  • Hi folks,

    Has there been any advances on this ? I've been messing with myuremote, which has enabled me to do some very basic IP control of my LG Smart TV (2013) today, with some fiddling but nothing serious - they have a method for revealing and sending the session token that I can understand (deep programming not my forte). But I am loathe to jump to a new system just for IP control as I am heavily invested (time and money !) in iRule.

    Is there any chance of irule being able to send this session token in the future ?

    Thanks.

  • Hi all. I want to control the new LG TV - OLED55E6V using iRule. Control codes can be found in device list. My question, how should i configure the gateway? Understand that I have to use port 1685, correct?. But should it be just IP control, HTTP Get or Put ? Nothing seems to work.. Help / suggestions much appreciated!

  • It would be great to get an update on this topic, as the latest LG OLED panels are considered to be the leading panels (see Value Electronics 2016 shootout) available and a premium product like iRule should control these by IP as well as IR (LG protocols permitting).

  • Hi All,

    If anyone is interested, I recently got an LG OLED 65E6 and tried IP control - it works.

    Wake on LAN is turned on and it starts up without fail - port 8020.

    I’ll try other IP controls over the next few days and let you know...

  • Hi Malcolm,
    Tried to make it to work, no luck. Using Putty the TV refuses the connection, did you enter a userid/psw?
    On port 3000 there is some sort of response but this port is the WebOS port. I found this on the Roomie web: https://www.simplecontrol.com/check-c... (no I’m not considering to move away from iRule!). This website also mentions that port 8080 should be used to access the ‘SmartTV’. Port 8020 is not mentioned here.
    Not sure what is going on with my setup, I'm pretty sure I have it configured right (ip address, 8020 port, control codes, etc ..
    I was pleasantly surprised by the fact the control codes can be imported from the iRule devices database. So that means that all is configurable and supported now.
    Any help much appreciated!
    Thanks,
    Hans

  • Malcolm,
    My mystery is 'solved'... iRule support (Mr. Alex Milogradov) advised: "Unfortunately, thanks to LG, only US versions are IP controllable with those codes."
    Why this is is beyond me, life in The Netherlands is not fair at times...

    Hi Guys,

    I can now report that, for some unknown reason, IP control of the LG OLED 65E has stopped working.

    No idea why - I have not changed anything - I still get a “green” circle in the bottom drawer of the app on my iPad.

    Any ideas?

    Having said that, the nature of the menu structure of the LG OS makes navigation with anything except the original remote next to impossible - try selecting a program in Netflix on the LG Netflix app...

    Back to IR control in the meantime...

    Cheers

    Malcolm

    I'm also trying to use ip controls for an LG - OLED55B6P with no luck, so far.

    I've tried using a NETWORK GATEWAY with port 9761 as Alex stated here - https://irule.desk.com/customer/porta...
    ...no luck.

    Has anyone had success with this?

  • On the LG site, the manual for the OLED55B6P DOES NOT include IP Control, but it does include RS-232 Control.

    The manual for the OLED65E6P DOES include IP Control and RS-232 Control.

    So maybe IP Control is only available for higher-end models?

  • Integrating LG 2016 "B" TV now. Trying to combine Magic Remote (webOS, very slick video cueing using native video app served by Plex) with iRule for power and input switching.

    LG manual states that Magic Remote is RF not IR, so turned to RS232. Using Global Cache iTach Flex and RS232 minijack cable, got power on/off and OSD on/off working... but nothing else. What's worse, RS232 disables Magic Remote (requires unplugging RS232 and cycling TV power to re-enable)!

    That leaves Network IP Control - supposedly enabled only in USA TVs (ours is). Before even trying to send IP commands (documented in some LG manuals, but not in my "B" manual), must access IP Control Setup menu to set Network IP Control sub-menu to ON and reboot. Problem is that instructions simply do not work: "Press and hold Settings button for at least 5 seconds on Live TV, wait for Live TV channel banner, then enter 828 and press OK". LOL. Before 5 seconds elapse, All Settings overlay appears, and numeric entries are ignored. Tried again after enabling Network > LG Connect and General Settings > Mobile TV On.

    Feel like a total fool here. Cannot even get to first base.

    Has anybody figured out how to enable Network IP Control? Do IP commands really work on these 2016 sets? Does Wake-On-LAN work to get power on in the first place?

    Is the problem perhaps that "B" sets have IP control disabled?

  • As I posted before, the IP control information is in the E6P manual, but it is NOT in the B6P manual. I would therefore guess the IP control is not in the B6P, but you may want to confirm with LG.

    If the lg has a webpage that controls it, you could embed a large web page window in an iRule page. I have done this, and it works pretty well.

    You could possibly start the lg app from within the iRule app, but then you have to exit the lg app and return to iRule yourself.

    Are the rs232 commands just not working, or do they not exist? You can add commands to an rs232 device, or edit existing commands. What Device are you using?

  • Our new TV is 2016 OLED65B6P, and I suspect that you are correct about IP control missing from the "B" series. I have queried LG technical support, and their preliminary response was essentially: "we don't know, but give us a few days".

    We would be satisfied if we could remotely issue Power On, Power Off, Input DTV, and Input HDMI2. I created an iRule device for LG RS232 from the manual, and as I wrote earlier, it worked for Power On/Off. The manual codes for Inputs are different from the ones in the device provided online by iRule, so if I fiddled some more, I might get Inputs working, too.

    That's all moot, however, because plugging in RS232 disables Magic Remote! If LG had not crippled the product like that, we wouldn't be having this discussion. Sigh. I'll just have to teach everyone to use both iRule and webOS Inputs to change from "internal" (Live TV, streaming apps) to "external" (Apple TV, BD, PC) media.

    There may be one last possibility. A year-old thread on Remote Central suggests that IR control is implemented on some of these TVs. In particular, one dealer chimed in that the "C" series (curved) OLED sets in his show room use IR. Anybody here know anything about that?

  • I've been somewhat successful in making IP control work on a 43UH610A (lowest of the low LG 2016 4K models). I do see that the IP control info that is in the owners manual available online for my model is missing for your model so it's probably right that the "B" models do not have it. I have found, though, that making the "828" sequence work for my model is quite tricky and at first I thought that it just didn't work (just like your experience). The trick to making it work is to watch closely for the channel banner to appear while you're holding the Settings button. (If it never appears, then you don't have IP control.) As soon as it appears, release the Settings button and do the 828 sequence as fast as you can. Doing this, I can get it to work fairly reliably. Any appreciable delay, though, will result in it not working. So, if you try this about 5 times and it still doesn't work, then it's pretty definite that IP control is not implemented on your model.

  • I have LG OLED55C6V and I've been desperately trying to access the service menu. Apparently, in some models you can do that with the API that uses the port 8080, such as with lgcommander. However, my TV does not listen to that port, so apparently the API is missing.

    Apparently, my TV uses the "Luna" WebOS Service API, which is at port 3000. I've been able to use it with the pylgtv library, but the API is different and apparently does not include the command to open the service menu.

  • Posting what I found as it might help someone. 65B6P is working with ip, to get in the 828 menu you need to program a universal remote, the fancy lg remote won't bring up the channel banner. When typing the 828 ok buttons, it seems to be more important to do it with a consistent rhythm instead of trying to go super fast. The port is 9761 in the gateway settings. Enable the WOL option and enter your mac. This is working over wifi for me. Oh also you need to enable the mobile control in the tv menu.

    Feedback seems to be an issue, I don't see any status commands and it seems the tv only responds OK (or NG if the command didn't work).

  • I think it's the app you can download, the wake on lan function needs it turned on. If you have wake on lan enabled in the gateway the tv will turn on every time you launch irule, so to turn the tv on add a wake on lan command in the builder and enter the mac of the tv, that is working for me. The problem I'm having now is that the overall control has just quit working. I assigned the tv a reservation in my router and I'm not sure if that is the problem but in the 828 menu it shows enabled but no commands are received and telnet quit working, etc. Also there is no feedback so on the whole I don't know what advantages ip control would have over IR anyway except to not have a blaster stuck on the tv.

  • If you go to the android store there is an app there that fully controls LG TV's. Mine is a 55OLEDB6 and it works fine.
    The app is ugly. BUT!! It has a trackpad type control and touching it wakes up the LG mouse pointer on the TV and you can move this all over the place and make selections.
    This is really excellent. Now, if something like this was available in iRule that would be amazing...
    I'd pay some cash for such a plug in. Perhaps the iRule team can reach out to the developers and see if they can provide such a plug in.

  • Has anyone tried this on the new (2017) generation LG OLEDs? I just bought a european 65C7V and according to the data sheet linked below, the C7-series should support IP Control. Still, I can't find any menu that activates this and I only get the "read" communication error status light in iRule when trying to send commands.

  • Finally figured out how to get the IP control dialog to appear on our new OLED65C7P (2017 US model).

    First, I added the MAIN MENU command from the "LG code group 1" via IR onto a button in iRule (or you could use a programmable remote). Make sure that it is set to repeat when held.

    Then hold this button down for 5sec until the channel banner appears.
    Then, switch to the magic remote, then enter 828 and then the central-wheel "ok" button (this last part is important!). You should then get the IP control dialog to appear. I can then confirm that it then listens on port 9761, the power-on/off IP control does work. Note that you must enable WOL and get the MAC address for the TV (six hex pairs separated by colons). I did all my testing on the wired ethernet port, not wifi.

    I did notice that powering on via IP then presented a dialog on the TV asking me whether I wanted to power on the STB, but it's working.

  • I actually gave up and bought an iTach IP2SL to get this working. I had some communication with LG support and they couldn't actually confirm if control via IP is available on european models or not.

    Maybe I will try your trick with an IR-command just out of curiosity. Where is the IR-reciever located on the TV?

  • The problem (as I understand it given previous context) with Serial control is that it messes with the remote-operation, and more importantly I don't believe power-on can work over serial.

    Not sure where the IR receiver is on the TV, I assumed it was near the red standby light was -- center/bottom.

  • Thanks! I currently only use power on, power off and input hdmi 2, and those three commands work just fine over serial - even power on so I guess that problem has been solved in more recent models!

  • For users of a RS232C serial cable with GC100 and 2017 LG OLEDs, did you use a null modem cable or a straight pass through serial cable?

  • You can download a 2017 Owner's Manual here:

    http://www.lg.com/us/support-product/...

    Scroll down to the EXTERNAL CONTROL DEVICE SETUP manual. From page 5, you need a crossed cable, also known as null-modem.

    You will need to set the GC-100 to 9600 baud rate, 8 data bits, no parity, and 1 stop bit.

    In the protocol, it looks like the Set ID is included in the commands. You can apparently change the Set ID in the TV settings. If you already have the iRule Device, you may want to check what the Set ID is in its commands, and set the tv to match. It also says " If [Set ID] value is selected to ‘0’, every connected set can be controlled."

    It also looks like you may be converting hexadecimal (hex) to decimal, and vice versa. I found an app called Dev Calc that does that for you. Very handy.

  • Thanks Mike. I was in the LG Extenal Control manual for an hour yesterday and never got past the pictures on page 4. I called LG Commercial Engineering and they had no clue about what I was talking about. When I spoke to Global Cache they thought the cable should be a straight through one to one cable. You are the first person to point out page 5 communication parameters. The reason I wanted to know the cable type was because the drywall is not up yet in the HT I am building and I wanted to get the right control cables in place before the walls get closed up. I have the GC 100-18R but I have not purchased the iRule software yet. I have most of my rack equipment and iRule will control it in at least 2 of the 3 options available. Thanks again Mike. I'm sure to be back again in the future. I hope all my questions will be as easy as this one.

  • I don't know if you are aware that the "RS232" connection at the TV end is actually a mini phone jack. So, there is no cable that you can buy that will connect directly from the GC-100 to the LG OLED. If you're at all comfortable with making cables, then the easiest would be to just run a 3 wire cable and and solder a RS-232 connector at one end and a phone jack at the other.

    There are 2 RS-232 to phone jack adapter cables available. Unfortunately, neither of these will go directly from the GC-100 to the LG (and probably are not nearly long enough to go though a wall). Each is different from the other, but what you will ultimately need in addition to it is a RS-232 cable plus a gender changer (and you need EXACTLY the right ones).

    I'm sorry to appear to complicate things, but I had to go through a lot to get it right and I thought that you would rather be aware of it now rather than later. I really think that wiring up the cable is the best solution in your case.

    While the walls are open is a good time to run one or more "empty" CAT6 cables. The pairs inside can be used for serial controls as above, or IR emitters, other low-voltage controls, or even phone lines if needed.

  • The additional comments are appreciated from Jacques and dlandiss. I was aware of the RS232 to 3.5mm phone jack cable converter, but as noted it is only 3 feet long. What I wasn't aware of is that LG is only offering a mini phone jack connection for external control on their 2017 models as Jacques indicates. The LG external control manual, page 4, suggests that USB, mini phone, and RS232 are available on their TV. The key words appear to be "connections can vary by model number". I am of the Heathkit generation so soldering is not a problem and I have plenty of CAT6e cable. My plan was to run a 25 foot female-female RS232 null modem cable from behind the TV location to the Sanus rack in the room next door. The RS232 to mini phone jack converter is a RS232 male shell with hex nuts on the end. I can then connect the 25 foot RS232 cable to the converter cable behind the TV. As long as there are no funky crossovers going on in the short RS232/mini phone cable it should work. In theory. I have not actually laid hands on an LG OLED 2017 TV yet so it is hard to know what model has what connections on the back. Maybe this is too simple, but couldn't you just run a 25 foot mini phone cable from the GC100 IR connection to the mini phone connection on the TV and get the same level of external control with the basic iRule software?

    Not likely. The serial protocol and the drive pulses for IR emitters are way different. The commands don't even have the same format.

  • LG hasn't made it easy then. Looks like it's RS232 or the highway. IP programming for LG control is where this thread started over a year ago and progress has been slow. One more thought about IR. How about a long mini phone cable that comes out below baseboard level right behind my center speaker stand. The mini phone cable goes up the back of the speaker stand and connects to an IR blaster that is basically pointed at the LG TV. The other end of the long cable goes back to the GC 100. Couldn't iRule control the LG that way?
