You can use the iotty Scenario functionality with Alexa.
To do so, you must first create the Scenario on the iotty app. Once created, connect your iotty account with the Alexa voice assistant and add devices.
Once the devices have been added, the Alexa app directly incorporates all Scenarios created and saves them in the Scenarios section.
At this point simply tell the voice assistant "Alexa run *scenario name*" or tap on the app icon to run the scenario.
