We are working on a toolkit / demo application where we try to visualize data coming from an OpenHAB setup. This setup sends some key values like electricity consumption and production. We are taking this information and putting it into an ElasticSearch cluster using MQTT, Xively and Logstash, and enrich the data with PLUS Energy building database from energy-cluster.ch and eco-villages.ch
The key thing we're trying to do is calculate PLUS Energy factor of the home - basically a number which says if it is energy-neutral/-friendly/-negative. We try to correlate this data, get a simple number, and create a dashboard visualizing these numbers.
Code and data is published on https://github.com/mojaconsult/swiss-energy-dashboard We need more data! If you have data from your house, please send it - format specification: https://github.com/mojaconsult/swiss-energy-dashboard/tree/master/data-publish
