To control lights and scenes via Alexa, Add an Ecotec Smart Switch or Scene in the Ecotec App. After discovering the devices using Alexa, you can control all smart switches and scenes easily. For example, after discovering the devices, say 'Alexa, turn on bedroom light' if its room name is 'bedroom',then the bedroom light will turn on by the smart switch. Say 'Alexa, turn on Movie scene' if you have a movie scene setup in Gateway and its name is 'movie',then the scene will be executed.
