Recipe: from MQTT to InfluxDB via Node-RED

• 2024-05-16 adds case study explaining how to extract values from topic strings, and how to specify the measurement name in the message payload provided to the "influxdb out" node.
• 2023-12-02 revise graphics to correspond with "influxdb out" node, and explain the pros and cons of InfluxDB 1.8 vs InfluxDB 2.

Introduction

Getting data produced by IoT sensors into a database is practically a mandatory step before effective visualisation (eg dashboards).

This recipe shows you how to get an MQTT payload into an InfluxDB database using three Node-RED nodes. It makes the following assumptions:

Hi,

I've been contacted by a talent acquisition associate offering me recruiting
services. He reached out to me directly on my personal cell phone number. I
asked him where he got my number and he said that his company invested in "an
API plugin called Lusha".

As an EU-based individual and in accordance to the General Data Protection
Regulation, I would like:

const applyTemplate = (templateElement, data) => {
  const element = templateElement.content.cloneNode(true);    
  const treeWalker = document.createTreeWalker(element, NodeFilter.SHOW_ELEMENT, () => NodeFilter.FILTER_ACCEPT);

  while(treeWalker.nextNode()) {
    const node = treeWalker.currentNode;
    for(let bindAttr in node.dataset) {
      let isBindableAttr = (bindAttr.indexOf('bind_') == 0) ? true : false;
      if(isBindableAttr) {
        let dataKeyString = node.dataset[bindAttr];

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
