enphaseapi
==========

This is a module to interact w/ the Enphase Envoy solar controllers.
It is designed to interact directly w/ the controller, and NOT use
the Enlighten cloud API.  This is for people who do not want their
personal information sold to third parties.

It will consist of two parts, the data logger part, that will issue
requests and write the output to a file (see the file start), and a
second part which will parse the log files and allow you to interact
with the data, such as fetch the data for a particular time.

Note: This code was written quickly so that I wouldn't lose the data
on my recently installed system.  It needs to be updated to be use proper
TDD, which likely could have caught some of the bugs/errors such as when
the Envoy goes off-line.


Credentials
-----------

There are two files that are used for credentials.  The first is
`creds.txt`.  The format of this file is:
```
<ip> <username> <password>
```

`ip` is the IP or hostname of the envoy controller.  The `username` is
usually `envoy`.  The password is what is set.

To get streaming line information (voltage, frequency, pf, etc), you
need the installer password.  This password is installed in the file
`creds.inst.txt`.

Scripts
-------

There are two scripts.  One is `start`, and this one provides the
collection of per panel and overall production information.

The second is `streaming`.  This outputs detailed, per second
information about the power line, including voltage, power, and
power factor.
