I was bored so I produced myself IoT NFC Distant . In this online video I use it to management Sonoff relays.
Basic plan is to have Internet of Things enabled NFC remote, that is battery powered. I connected it utilizing MQTT to mosqquito and also employing WebSockets specifically to Node-Crimson managing on RPi3.
Programed using System.IO (ESP8266 arch)

3D documents are developed in OpenSCAD I will add them to thingiverse sometime.
