People are heading home. Some of them will pick it up tomorrow.

Murmurs of technical discussions. Serious concentration.

Just the clicking of keys and mice...

There was a long wide-ranging discussion about the achievable goal for the Hackdays. The general gist was to establish a middleware layer handling each meter's unique format to "re-publish" the data in a common format, but there was no agreement yet on what that format would be.

... OpenHAB ...

All four meters feeding into MQTT, forwarded to InfluxDB and re-published under a uniform basic profile back to MQTT. Visualization using Grafana and OpenHub in place.
