Smart speakers, such as Google Home or Amazon Echo, are entering our homes and enriching the ecosystem of the Internet of Things (IoT) already present in them. The Intelligent Personal Assistants (IPAs) they include allow users to ask for different information (e.g. the weather or a recipe), set reminders and lists, and directly control other IoT devices (e.g. lamps). These assistants, through a companion app installed on the owner’s smartphone, provide advanced features like the possibility to set up some personalization rules in the form of trigger-action: if something happens, then do something else. In alternatives, there are visual programming tools such as IFFTT or Node-RED that allow for more complex management of IoT by creating also complicated rules, but these tools lack simple management and require some effort by less technical users.
