The last few months I wss busy with a SmartBuilding solution for some of our education clients to save square meters and give an app to studenten to find free rooms. Later I will create several post about the technical solution, but I have created (sorry its in dutch) white paper about this topic.

Connect a Sigfox IoT device to the Microsoft Azure IoT Hub

Connect a Sigfox IoT device to  the Microsoft Azure IoT Hub

Since this week I have a Arduino Sigfox Snootlab IoT device connected to the ‘real’ Sigfox Backend system.(before I used an other backend system of Snootlab). With a device like this you can monitor anywhere in the Netherlands (IoT network) for example if a trashcan is full or not.

One of the reasons for doing this move to the Sigfox Backend system, is that I want to have an integration between the Sigfox IoT network and the Microsoft Azure IoT Hub. The Azure IoT Hub that we are using a lot in our IoT projects at Winvision. Since a couple of weeks Sigfox has a ‘connector’ to connect your IoT device to the Microsoft Azure IoT hub, and it’s really simple. In this small tutorial I will explain how it works.

First of all, if you are using the Akene board(like below) with Arduino, here you can find the library for the board.

First of all go to the Sigfox backend:

Here you see all your Sigfox connected devices. Click on the name to get the details of the device.

On the right top you can find a New button, where you can create a new callback to another system.


Select the Microsoft Azure IoT Hub

After selecting the Microsoft Azure IoT hub you get in the screen where you only need to fill two configurations items(and that’s it!)

You need to fill in the Connection string of your IoT Hub (you can find this in de Microsoft Azure Portal) I choose the iothubowner connection string.

After that you need a JSON body for receiving the right data (and you can use off course use your custom data)

“device” : “{device}”,
“data” : “{data}”,
“time” : {time},
“duplicate” : {duplicate},
“snr” : {snr},
“station” : “{station}”,
“avgSignal” : {avgSnr},
“lat” : {lat},
“lng” : {lng},
“rssi” : {rssi},
“seqNumber” : {seqNumber}

Click save and that’s it🙂 !

Turn your Arduino device on and it will send the data to Sigfox and Sigfxo will send it to the Microsoft Azure IoT Hub.

To test if your data is received by the Azure IoT Hubyou can off course use Azure Stream Analytics with Microsoft Power BI. But for this post I just use the Iot-hub Explorer

With this tool you can see the messages that the Microsoft Azure IoT Hub is receiving in realtime.

Below you see the data of my device 77D3C on the Microsoft Azure IoT Hub. I have made the keys red. And it’s working!

Afer all Sigfox made it really SIMPLE to connect you Sigfox IoT device to the Microsoft Azure IoT Hub!
