It's 70 euros, which is an insane amount of money for a button, and it's huge :/ The one posted above is small enough to unobtrusively stick on a wall and less than half price this one. Hopefully they'll come out with a standalone mod.
Does that have a cellular modem/wifi module? Seems like you'd need to connect it to a Photon or Electron to get connectivity.
The first line on the link is "The Internet Button includes a Photon, which can also be easily removed and used for other projects, a USB-micro cable and a removable plastic cover."
