You will need to use the ControlHome SE application for iOS or Android to connect your Controlhome switches to your home WiFi network and provide names for each device. Open the home screen in the Alexa app, select "Get more smart home skills," select the Controlhome SE skill and press "Enable Skill." The Alexa application will take you to an Amazon page that will allow you to link your Alexa profile to your home in Controlhome, an important detail here is that the same email used at the time of registration of the Controlhome SE application should be used in the Alexa registration. For best control performance, specify a clear name for each device in ControlHome, such as "Kitchen", "Hall" and "Garage". To control your devices, say "Alexa, turn on / off my <switch name> lights", such as "Alexa, turn on kitchen lights", "Alexa, turn off kitchen lights"
