I was looking on the LG developer site and found this.

I haven't had time to really look at it but I think it describes how control these tvs.

Not being a programmer myself I would be interested to know if this opens up control of these tv over IP. If so I would be interested in commissioning a driver.

Ughhh... It's almost UPnP, but it's not. Why didn't they use use UPnP? Stupidity, dude.
Anyhoo, it seems to all be documented. One gotcha though is that it probably won't be possible to do a driver remotely, because like UPnP it's going to depend on broadcasts. That will make it hugely annoying to try to do a driver without having one local.

Actually, looking at it some more, I'm not sure if this is for external control, or for the development of programs to run on the TVs. It's hard to say just from a quick read.

It looks to be both.
Under the references section there is a remote control service that appears to mimic the remote commands...

Oh, OK, it looks like it actually covers both, which is why it was so confusing at first. There's an API for programs that run on the TV, and the UPnP type protocol for talking to them. [you beat me to it].
But, as best I can tell, it's all but useless for automation purposes. You can get some information, but I can't see anything for actual control. There's one direct command I can see to set the channel, and everything else seems to be oriented towards just using a phone as a remote keyboard input to the TV to input info into apps or some such.
That would be a lot of work to get very little useful functionality, it seems to me.

that wouldn't be useful at all...
There is this that shows the key codes that the remote controller excepts.

But that's just basically fake keyboard input, i.e. it's running the menus remotely, not direct commands per se, which isn't really useful for automation. Menu types commands like that depend on the menu context generally. It looks like they really just see this as a 'remote control on a phone' type thing.

The problem we keep running into commercially is that there really is no feedback, so you can not monitor power. We have to install RS 232 current sensors to keep everything in synch. This applies to both LG and Samsung to some extent. It really depends on the display. The commercial displays are all still OK, but the consumer would pay dearly for the commercial level displays.
Thanks,

How exactly do you do this? I ended up putting one of USB pen lights hooked up to a GC-100 to determine whether the TV is on or off, but would be interested in seeing how I could hook up an RS-232 sensor to my LG TV and continue to use the USB to RS-232 dongle to control it.
