To control light and TV Alexa, Add the light switch (Feedback Switch) extension of the Gateway or TV in the Home+ App. After discovering the devices using Alexa, you can control all (Feedback Switch) extensions and TV easily. For example, after discovering the devices, say 'Alexa, turn on office light' if you have a extension device (Feedback Switch) and its room name is 'office light', then the office light will turn on by the light switch (Feedback Switch).
