I am from the Alexandra Institute as well. I have been working with Mirko Presser for quite a few years, and am involved in different initiatives around LoRa (and a little on TTN). The Alexandra Institute has deployed two LoRa gateways until now (I have two more at my office, that are just waiting to be deployed
I have discussed both with jacand (my colleague), and Kim Søvsø, who has replied earlier in this thread. Furthermore, I/we have quite good connections to the department, within Aarhus municipality, that is going to fully equip the city with LoRa (17 Kerlink gateways).
I can take the initial lead, and let's see what will happen. Should we have a physical meeting to make things going or do you prefer to be virtual? The Alexandra Institute would be happy to host the meeting depending on how many are interested.
I will join the slack channel, and we are doing something at the internetweek: http://internetweekdenmark.com/events/nyt-iot-netvaerk-i-aarhus + http://internetweekdenmark.com/events/hackathon-co-creating-the-smart-city.
At the latter event LoRa is more like an add-on, but it's a pre event for being able to apply for money to e.g. play around with LoRa in Aarhus.
