Posting this here to warn others that updating your LG TV software to the latest version will stop the LGWebOS binding from working.
Other discussion going on this thread, as well as on the Home Assistant forum.
After updating one of my TVs to 03.30.16 OpenHAB can no longer control the TV. Wake-on-LAN still works however.
It looks like the issue has been identified but someone with Dev skills will need to look at it.
Should I open an issue on GitHub as well?
