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 (There is also a command/query list below the examples)

This project was inspired by PHP-LG-SmartTV by SteveWinfield
