Fronius Inverter (symo) Data

You will find the API doc from Fronius for reference. If things don't work as expected, read this document.

This code is still very much a work in progress and still largely untested. The api functions are usable but it's not in a package. There are a number of calls which I cannot test due to my install options. I'm still trying to figure out what much of the data means.

Use at your own risk - some of the code may save you some typing :)

Collect data from the fronius Symo and log to sqlite database

Assumes you have host 'fronius' your /etc/hosts file.

Creates a sqlite db called fronius.sqlite with two tables called Site and Inverters

Queries the Inverter every 5 seconds.

1. Test and cleanup function options
2. Build option to return json or csv data
3. Create a Module.
4. Add code to check that Inverter is up before doing anything. Necessary if powered by sunlight only
