This plugin can be used to interact with newer (2016 and later) Samsung Televisions. The plugin provides a single device, which is an extension of the SwitchActuator, and can be used to turnOn and turnOff the TV. Nothing more. The device config only requires the the IP address of the TV (the mac address will be automatically obtained and populated by the device).
The first time you turn off the TV using the device, you must be in front of the television to approve the request.
It may be possible to send additional keys beyond KEY_POWER, but I have not tried others. While I’m happy to help anyone having issues with this version of the plugin, I will not be expanding it’s capabilities. I created it for the sole purpose of turning on and off the television.
I have a KS8000, and can confirm it works perfectly. It actually works better than the SamsungTV device provided by SmartThings.
