Dear Node Red community,
I'm building my own IoT demonstrator as kind of a university project at the moment.
I connected a DS18B20 temperature sensor to a Raspberry Pi and from there to Node Red.
The thing I struggle with, is identifying the elements of the IoT Architecture. The Pi would be the device communicating over the Gateway (The universities Wi-Fi Router) with Node Red, but where in all this would be the Middleware? Is it the Http Protocol processing the request send form the Pi?
Thank you for your support!
