Node-RED is a visual programming tool focused on expressing data flows as linked nodes that perform functions on the data. In theory no coding is required.
We each suggested a scenario to implement, to make it more concrete. I opted for a solution where a Pycom LoPy (it could have been any of the Pycom boards, as I used WiFi), connected to a Pysense sensor board, would send the sensor data in JSON format via MQTT over WiFi to an MQTT broker running on my PC that then Node-RED subscribed to. The rest was implemented in Node-RED.
I believe Node-RED can be a useful tool for quickly creating situation- and customer-specific sensor data logic and visualizations, complementing other solutions.
