Hi All: Thanks to everyone at Ubidots and and the Ubidots Community! I teach IoT in Singapore and my students love using Ubidots to create IoT projects (even though I'm teaching Amazon Web Services IoT, a much more complicated platform).
I work for UnaBiz, we are the Sigfox network operator for Singapore and Taiwan. Some schools here have asked for Ubidots support, so I have created some code that integrates Sigfox devices into Ubidots.
The code runs on Google Cloud (because it's cheaper than AWS and Azure). It receives Sigfox messages via the standard Sigfox HTTP callback interface and calls the (very well designed) Ubidots API to push the Sigfox messages into Ubidots as Ubidots Devices and Variables.
But it's not fully automated - you need to create the Sigfox device in Ubidots and fill in the variable names. Below is the code and a simple guide for creating Sigfox devices in Ubidots. Anybody else here interested in Sigfox integration?
