Managed Identity on Azure Arc Servers
When you install the Azure Arc agent on any physical or virtual server, either Windows or Linux, the machine suddenly starts living in a cloud world: it appears in the Azure Portal you can apply resource tags you can check for security and regulatory compliance with Azure Policy you can enable Update management and much,…
armMulti-Tier Bitnami Grafana Stack on Azure
After seeing some tweets about Bitnami’s multi-tier Grafana Stack, I decided to give it a go. On the page describing the Grafana stack, there are several deployment offerings: I decided to use the multi-tier deployment, which deploys multiple Grafana nodes and a shared Azure Database for MariaDB. On Azure, the Grafana stack is deployed via…
analyticsAdaptable IoT
On May 24, 2017 I gave a short partner session at Techorama, a technology event in Belgium for both developers and IT Pros. You can find the slides on SlideShare: https://www.slideshare.net/gbaeke/adaptable-iot Since it was a short session and a short slide deck, this post provides a bit more background information. First, what do I mean…
analyticsControlling Sonos from a Particle Photon using a Sonos API on a Pi 3
In the previous article, Control Sonos with a easy to use API, we configured a Docker container on a Raspberry Pi 3 to run an easy to use Sonos API. I prefer this solution over writing code on the Photon to control Sonos. Now it is time to let the Photon talk to the API…
apiControl Sonos with an easy to use API
In an earlier post, Controlling Sonos from a Particle Photon, we created a small app to do just that. The app itself contained some C++ code to interact with a Sonos player on your network. Although the code works, it does not provide you with full control over your Sonos player and it’s tedious to…
apiTemboo, Twilio and Nexmo: SMS and voice messages from your IoT device
In this post, I will provide an overview of how to use Twilio and Nexmo to send SMSs and voice messages directly from your device. I will use a Particle Photon but this also works from an Arduino, or a Raspberry Pi or basically any other system. The reason for this is that I will…
apiControlling Sonos from a Particle Photon
Now for something fun! Let’s control a Sonos from a Particle Photon and a connected button. I connected a Grove Button to the Particle with simple male-to-female wires. The SIG line on the button should go to a digital port (D0 in my case). When the button is pressed, the port will read HIGH and…
armParticle and Azure IoT Hub: forward events for storage and analysis
In a previous post about Partice published events, you have seen how to publish custom events to the Particle Cloud. Other devices or applications can subscribe to these events and act upon them. What if you want to do more and connect these events to custom applications? In that case, Particle has a couple of…
armIoT with Particle and Porter
In an earlier article, we took a look at Particle Functions and Variables. We wrote a simple application that can blink an LED with a function and read the value of a photoresistor with a variable. Although you can easily call the function or read the variable with the Particle CLI or with a REST…
armIoT with Particle: publishing events
In the two previous posts, we discussed setup and talked about triggering actions and reading sensor data. Particle also allows you to publish events. You can subscribe to these events or pass them to other systems such as Azure IoT Hub. Let’s build on the previous example with the LED and the photoresistor. When we…
armIoT with Particle: Functions and Variables using the Build IDE
In yesterday’s post, I talked a bit about the setup process and initial configuration of a Particle Photon. To start quickly, we used the Tinker firmware and the Particle iOS app to light up a LED using digitalWrite to light it up with full brightness (full 3.3V) but also with analogWrite to vary the brightness…
armIoT with Particle: a smooth experience
At ThingTank, the IoT brand of Xylos, we make our own IoT hardware which can be quite complex if you need to connect multiple sensors efficiently, or even multiple MCUs where each MCU has its own set of sensors. Most people that want to start with IoT (typically at home or for a small company…
