How setting up and start this application:

• Have at least one piko inverter from Kostal (www.kostal-solar-electric.com/)

• You can access it through your network by a fixed IP address and you know username and password to read data

• Create and configure database.yml and secrets.yml (in config folder)

• Create database and run migrations

• Add inverters and zones in database (with rails console for example, currently no UI to do this)

• Configure cron jobs with whenever gem (be sure bin/rails has execution rights) and restart cron service

• Et voilà :-)
