Installation ^^^^^^^^^^^^
To install EnergiStream from source, clone the git repository to your local machine ::
$ git clone git@github.com:melrok/energistream-py.git
In the :code:energistream
root directory (same one where you found this file after cloning the git repo), execute ::
$ sudo pip install -e .
Dependencies ^^^^^^^^^^^^
EnergiStream has a few key dependancies:
pandas <http://pandas.pydata.org/>
__: >= 0.14.1requests <http://docs.python-requests.org/>
__: >= 1.2.3testfixtures <https://pythonhosted.org/testfixtures/>
__All requirements are specified in the requirements.txt
. One can attempt to install these alongside the EnergiStream
installation via ::
$ sudo pip install -r requirements.txt -e .
EnergiStream Guide
A quick guide to some of the core EnergiStream functionality. Examples and additional documentation are available at GitHub Pages <http://melrok.github.io/energistream-py/>

Note : Always refer to the doctrings for all methods for a detailed summary of functionality.
Importing ^^^^^^^^^
To import the energistream library :
.. code:: python
import energistream as es
Client Instantiation and Authentication ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:code:EnergiStreamClient
takes a valid username and password and establishes a unique session with temporary credentials.
.. code:: python
stream = es.EnergiStreamClient('USER', 'PASS', include_sensors=True)
:code:authenticate
uses the user credentials to authenticate the instantiated client in the event that authentication was not previously established or has lapsed.
.. code:: python
stream.authenticate
The :code:is_authenticated
method returns a simple boolean true or false when asked if the client authentication is still valid.
.. code:: python
stream.is_authenticated
External Data ^^^^^^^^^^^^^
The :code:get_weather
method returns a dataframe of hourly temperature and relative humidity data for the instantiated client's associated physical location.
Note: This data is collected from third party sources. Weather ID is an energistream unique key and not associated to any third party ID schema.
.. code:: python
stream.get_weather(weather_id = 102, start = '12/29/2014', end = '1/29/2015')
Energistream Data and Metadata ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The :code:get_energy
method accepts a sensor ID and returns a dataframe relating active and reactive energy, current and voltage RMS, and total Energy.
.. code:: python
stream.get_energy(3505, start = '12/29/2014', end = '1/29/2015', tz = 'local')
The :code:search_group_tree
method accepts a keyword and searches the instantiated client for matching sensor groups returning group names, sensor group ID, and assigned sensors.
.. code:: python
stream.search_group_tree('Engineering', case = False)
The :code:base_group_level
column designates the grouping hierarchy by levels, with 0 being root groups.
.. code:: python
stream.groups[stream.groups.base_group_level == 0]
The :code:sensors
method returns a dataframe describing the individual sensors associated with the instantiated energistream client ID. This includes the sensor ID, the associated group ID, time zone, and a multiplier based on the method of measurement i.e. one, two, or three channel.
.. code:: python
stream.sensors
The :code:get_boards
method returns a dataframe describing the boards associated with the instantiated energistream client ID. This includes
the boards serial number, version, display name, and model.
.. code:: python
stream.get_boards
The :code:get_demand
method returns power data for a given sensor group(demand or generation) at multiple resolutions (1, 5, 10, 15, and 30 minutes, daily, weekly, monthly, and yearly). Start and end date may be specified as well as the timezone and desired resolution.
Note: Defaults to the last thirty days and fifteen minute resolution.
.. code:: python
stream.get_demand(157)
