I will build/demonstrate an application which can interact with devices (IoT) such as a coffee machine. First, I will show how this is build and how you connect devices and let them do something. I will use a Raspberry Pi for this. The human interaction with this application makes use of AI: to translate speech into text and the other way around in a contextual way. Another part of this demonstration is how you can send the status of those devices to, for instance, a Slack channel. So it involves more then IoT, it involves also AI, integration with other platforms and it is built with Node-RED which is an open source tool (based on Node.js) very suitable for this.
