Node LG TV API [beta]
=====================

A NODE API for the LG SmartTV (2012+) which makes it easy for you to remote control your TV with code.
You"re able to execute simple/special commands and queries (change channel, get current channel,
get channel list, set volume up, set volume down, save screenshot - save gif animation, ...)

You can find command parameters and query structures on the [Official Documentation of the LG SmartTV](http://developer.lgappstv.com/TV_HELP/index.jsp?topic=%2Flge.tvsdk.references.book%2Fhtml%2FUDAP%2FUDAP%2FHandleTouchMove.htm)
(There is also a command/query list below the examples)

This project was inspired by [PHP-LG-SmartTV by SteveWinfield](https://github.com/SteveWinfield/PHP-LG-SmartTV)
