Integrating Particle.io with InfluxDB Cloud

If you followed the tutorial I presented a couple of years ago about integrating Particle.io with InfluxDB and were unhappy, or simply couldn’t get it working, have I got a treat for you! Integrating Particle.io with InfluxDB Cloud is very …

The World’s Smallest InfluxDB Server

I’ve built a lot of InfluxDB servers in my time here, and I’ve built some pretty esoteric ones at that, but I think I’ve finally pulled off what can only be described as the World’s Smallest InfluxDB Server! Back in …

Using Flux to Get IoT Sensor Metadata from MySQL

If you’ve deployed an IoT solution, you’ve had to decide where, and how, to store all your data. At least from my perspective, the best and easiest place to store the sensor data is, of course, InfluxDB. My saying that …

Connecting The Things Network to InfluxDB

There are many ways to connect your sensors to the network in the IoT. For short-range connections, there is Bluetooth LE, or Zigbee, or 802.15.4, or ZWave. For longer distances (though still fairly short) there’s always WiFi. But when you …

Hiding Complexity with Custom Functions: Calculating Heat Index

Have you ever watched the local weather — or The Weather Channel — and heard them announce the temperature, and then the “Heat Index”? Or how hot it feels outside? At least here in the United States, and especially in …

How to Output Data from Flux to MQTT Natively

Writing data from InfluxDB to MQTT using Flux I started using the Open Source (OSS) version of InfluxDB v2.0 very early on in the Alpha releases. Even in the early releases, I was very enamored with the way things were …

Revising the Demo Hardware

If you’ve been reading me for any length of time at all, you’ll know that I build lots of little hardware projects. What better way to highlight the IoT capabilities of InfluxDB than to build hardware that writes data to it …

Publishing Data to InfluxDB from Swift

I’ve been a very busy man. It was only a few days ago that I wrote about a new InfluxDB library for writing data from Arduino devices to InfluxDB v2 and here I am again, writing about a new library for …

Writing Data from Arduino to InfluxDB v2

As InfluxData moves ever closer to releasing v2.0, it’s becoming increasingly important to be able to get data into InfluxDBv2, of course. Makes sense, right? Since the vast majority (like, indistinguishable from 100%) of my data comes from IoT devices, I …

Practical Uses of Cross-Measurement Math in Flux

I’ve been spending a lot of time lately with the 2.0 Alpha releases and I’m here to tell you: some of the new things coming are really, really cool! Especially for IoT. The one I’ve been using lately has been …
