IoT 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…
IoT 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…
IoT 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…
Have some fun with Slash Webtasks and Slack
At ThingTank we really love a tool like Slack because of its simplicity and extensibility. Like so many, we use it to get notifications from all sorts of systems. A lot of websites and tools integrate with Slack such as Azure Logic Apps or CI systems like Shippable. Those types of integrations are very easy…
IoT Hub Scaling
When you work with Azure IoT Hub, it is not always easy to tell what will happen when you reach the limits of IoT Hub and what to do when you reach those limits. As a reminder, recall that the scale of IoT Hub is defined by its tier and the number of units in…
Adding natural language to your Bot
In the last post, Bots in an IoT context, I created a very simple bot to request the air quality in a room. To change the room, you had to type change room and then type the room name when requested. It would be much nicer to be able to give commands like change room…
Bots in an IoT context
At ThingTank (@thingtankBE), we are constantly looking to expose IoT data in different ways. A chat bot can be a great way to ask for device measurements or even instruct devices to perform actions. In this post, I will describe a bot that gets air quality data for a meeting room with Slack. I chose…
Azure Automation and PowerApps
One of our applications in our “test playground” is running some code in an Azure WebApp that needs to be restarted once in a while. Rather than trying to fix the underlying problem (no fun in that right?), I decided to create a small mobile app to restart the WebApp when needed. To make it…
Your Internet of Things: from data stream to insight (Seminar)
A while back, my colleague Tim Jacobs and myself gave an introductory IoT session at our Xylos Technology Day. I actually forgot to put this on my own blog. Better late than never.
Using Azure Cognitive Services from Logic Apps
Azure’s Cognitive Services are very easy to use from within your own applications or more “code-less” solutions such as Azure Logic Apps. In this post, I will show a simple example of a Logic App that does sentiment analysis on incoming tweets. When the sentiment score is very high, an SMS is sent. To perform…
