alt Hacker NewsThe definition of "IoT" requires neither Internet access nor cloud server functionality.
https://en.wikipedia.org/wiki/Internet_of_things
The core idea of IoT is that everything is capable of communicating on some network, whether that device is a fridge, a coffee maker, a dishwasher, a speck of dust, or a light bulb. The idea is that networks can connect more types of "things" than just general computing devices. The type of network and the reach of said network is sort of immaterial.
The author has created a specialized widget which communicates over a network. By definition, that is IoT.
To be fair, while the definition does not require internet connectivity, the name certainly does imply that it does.
Even the linked Wikipedia article points this out:
> "Internet of things" has been considered a misnomer because devices do not need to be connected to the public internet; they only need to be connected to a network and be individually addressable.
