Hello Jan,
I am currently running a gateway in Hilversum, The Netherlands. I do have an opportunity to place another gateway near Düsseldorf, in Mettmann to be exactly.
Are you a bit familiar in building sensors and stuff like that? I am interested in the smart city and smart living. (connecting the heating, the airco, home automations, garden automations, etc). I have a background of IT Infrastructures and Service Orchestrations, but not really the real technical sensors. I do like to learn though!
Kind regards,
Jeroen
