[PORT] LG Smart TV Discovery 2012+

I have LG C8. Can I use any of the app/driver listed in this thread to know when the LG remote was used to pause or stop media playback? We watch movies on my tv using the media player within the tv from my external harddisk. When I pause a movie, it will be nice to have lights brighten up a bit.

I'll add my voice to the chorus of folks who can't get the ON command to work. Everything is perfect; can't make the ON command work no matter what I try.

A couple interesting observations from troubleshooting:

  • my ON worked for quite awhile, then all of sudden stopped a couple weeks ago. Mysterious. I did have to upgrade my mesh router -- maybe that's why. I have 4 LG TVs -- all models from the last year or two. The ON command stopped working on all of them. Besides that one command, they all work flawlessly -- thank you @asj.j
  • some have reported using 2.4g instead of 5.0g on wifi made a difference. Didn't for me.
  • others reported that using wireless vs. wired made a difference. Didn't for me.
  • I was able to get the LG TV Plus app to turn on the TV, but not consistently. A clue perhaps.
  • I tried a WOL app and it didn't work either, but I only tried briefly and gave up.
  • Yes, Mobile TV is set to ON.

I called LG support yesterday (kill me now!). They of course didn't want to lift a finger ("Why don't you submit a feature request?" :hot_face:), but I insisted they should find out if WOL was restricted or some other change was made to firmware. They said they'll get back to me Thursday. Uh huh, we'll see about that.

Any ideas?

Is this app available on Hubitat Package Manager? That will be really nice if it can be made available there so that we can easily get the latest version installed.

I wonder if something changed on the Hubitat? Just tested with my tester hub and works with my old LG tv. Hubitat so is ancient, tv is old….but maybe Hubitat has stopped send WoL frames.

Or have you put in a smarter home AP/switch and it’s filtering these frames?

There is a fork of the app and drivers available in the HPM.

It’s also possible to browse available packages with @bptworld’s package explorer app (conveniently available in HPM as well).

I don't think so, but who knows. I just tried this WOL app, and it works for me.

For everyone who has the "ON" problem may want to try a work-around where turning on the TV through the LGTV app fires off the WOL device -- not elegant, but it'll work.

@asj, I ended up using WOL (per above) to work around the On problem. Not elegant, but it works. Unless I noticed that "Home" doesn't work either. I tried every other command in the driver and they all work, except for On and Home. And I don't see a workaround for Home.

I actually wonder if LG changed their interface somehow.

Any ideas? Would it be helpful if I shared logging?

So far, it has not found my C1 set. Could you add a function where I can tell it the IP address. That always works.

It showed no updates.

I am using LAN and it was still not found. You should be able to just program the IP address. That always works.

This is, by far one of my favorite apps I have found on Hubitat! Thank you. Im having a little issue where I can only add one TV, it does find both but once one is set up it goes through without sending the on screen prompt to the second? Also it is stubborn and will only find one TV at a time :man_shrugging: Any ideas?

Also is there a way to use the 'Pause' and 'Play' buttons?

Just running into this also, I can add either tv at one time but not both together. The child device is created for the second set and is missing only the pairing key. I’ve tried downloading some 3rd party LG Remote apps hoping that they would expose their own pairing key and I could just copy/paste but nada so far. No apps I’ve tried seem to show it but there are many on the App Store I have not tried. This may work… otherwise, like you, appreciate any suggestions. If you figure it out please do let me know!

Actually just occurred to me:

-Pair TV 1, go into child device, copy pairing key.
-Delete app which deletes child devices then reinstall and pair TV 2.
-Pair TV 1 again, it will fail pairing but your key should still be save by the TV. Copy the key you saved into TV 1 child device.

Seems logically like it might work, will try tomorrow.

So, after a little play I have found a workaround. Seems that when both devices are created it does not like initializing them immediately so I have written a rule to run when the power is turned on to wait 60 seconds then custom run the initialize button which then forces the TV to connect. Otherwise it just spams the logs if you retry every minute or so.

Bit of a work around but it works for me.

Hi, can someone please explain how do I obtain a pairing key?

I'm having the same issue. Any luck?

@yototogblo Can you please explain what exactly did you change in the code? as my C9 also goes with the turn on/off commands

It's been over a year so don't remember what exactly I changed. I made a bunch of changes though and my TV has been working flawlessly since then so I haven't revisited this. I did disable the mouse driver as I never use that.

Below is my code:

 *  LG WebOs TV Device Type
 * ImportURL: https://raw.githubusercontent.com/as-j/LG_Smart_TV_hubitat/master/LG_WebOS_TV_Driver.groovy
 *  Notifcation icons are fetched from: 
 *  https://github.com/pasnox/oxygen-icons-png/tree/master/oxygen/32x32
 *  They are named without extention as: <directory>/<file>
 *  For example:
 *    - file status/battery-low.png has an icon name: status/battery-low
 *    - file actions/checkbox.ping has an icon name: actions/checkbox
 *  They can be used in a notifcation message formated as:
 *  [icon name]Notification Message
 *  For example:
 *  [status/battery-low]My Battery is low!
 *  Or you can use the custom command "notificationIcon" which takes 2 strings
 *  the message, and icon name

I can't seem to remember what I did to get the pairing key. I'll let you know if it'll pop up again

Thanks. Unfortunately if didn't improve my situation. I'm not really sure why my simple command is not working. The on/off on the lg device app works and the on/off of my Govee strip device app also works, but a simple rule that says to turn on/off the strip if the tv is turned on/off doesn't work. it's really strange...
