Just another GPS tracker, using an Atmel 328P, they published the source code: https://github.com/hidnseek/hidnseek, Product info: https://www.hidnseek.fr/shop#st1a . Sigfox is not compatible with TTN (?), but the GPS and LowPower part of the code are interesting.
They’be just launched a LoRaWAN version too
IMO the same post and the same product. They use SIGFOX technology (Telecom Design TD1207 SIGFOX modem), IMO this module can not connect to TTN: http://www.link-labs.com/sigfox-vs-lora/ , EIN news is not that clear in their usage of ‘LoRaWAN’ .
They are very similar but definitely two different products. The LoRaWAN version was announced days ago.
The LoRaWAN version - named ST1-L - uses the popular Microchip RN2483 module so it’ll be able to connect to TTN (if set to do so).
Of course since there’s no live TTN network yet I think the devices out of the box will come ready to connect to the Objenious network by Bouygues Telecom, maybe others.
I like their idea and it’s a testament to how someone can take a fairly standard, just optimised, Arduino configuration and turn it into a sucessful viable commercial product with thousands of users already. No fancy protocols, microcontrollers or advanced sensors needed. Even the GPS module is well known and popularised by Adafruit for example.
A reminder to stop complicating and start shipping 
True, we were triggered by the same post on the news site. Their website though shows only the SigFox Device. All clear, and agree on your point of start shipping. I did setup my own gateway, but waiting for (many) others to come
HidnSeek host a TTN Gateway and trackers are connected to TTN. Some work need to do to integrate our server. First position message near Grenoble :
