I've built a didactic experimental IoT for you. I'd like to share with anyone who is ready to achieve this idea. This object is ready to be used in your Wi-Fi 2.4 GHz network. It works with MQTT protocol and can be used with various clouds and on-premise brokers. You can download the firmware to load on Arduino MKR1000 and the masters to bild printed circuit boards.

The bill of matirial is available on this. To load the firmware, I suggest you visit my video archive.
The sketch uses 108696 byte on 262144 byte (41%) of the available space for programs.
If you should need further advice or help in building it, feel free to contact me.
The first draft of this idea was not very successful, but I try to give a new interpretation where anyone can use it as a starting point for their own ideas.
