CodeOverview
Opengrid consists of several classes and software packages. I propose to use this page as a general overview of the intended functionality of these components and the interactions between the components.
found in root/library
This module allows to pull data from the flukso servers.
This module contains functions for fetching (all) sensor data / metadata from a google spreadsheet using gspread.
This module stores timeseries data in a more disk space efficient way then fluksoapi.py. For each sensor a separate datafile and metafile are created. This module also provides functions for fetching data from the stored files. Usage:
tsd= TimeSeriesData(sensorid)
tsd.getAllData() -> returns a dictionary with two lists: one list containing timestamps and one list containing the measurements (stored as floats).
Contains jobs and (interactive) scripts.
Jobs are tailored scripts to run on the opengrid virtual machine on a regular basis through a crontab job. Therefore, jobs can have absolute path settings and functionality that is only useful on this server. Every job has a filename starting with job_. Most jobs will be normal python files (no ipython notebooks).
Scripts are pieces of code with a specific goal, like one type of data analysis. They should be programmed in such a way that they can run on any computer configured with opengrid code. Often, scripts are work in progress, and have the ambition to evolve into a job.
We have three virtual servers:
http://95.85.34.168/
root = /var/www/public
http://95.85.34.168:8080/
root = /var/www/private
http://95.85.34.168:5000 root = /usr/local/src/website

Sensor categories for electricity sensors. See also issue 54
Examples:
- gridElecExport : metering of electricity export via grid connection
- pvElecProd: electricity generation of PV-system
- gridElecImport: metering of electricity import via grid connection (non-reversible)
- gridElecNet: net metering of grid connection (reversible meter)
- siteElecCons: total electricity consumpion after grid connection, including self-consumed PV-generation
- gridWaterImport: metering of total drinking water import
- CircuitElecCons: submeter of gridCons
- gridGasImport: metering of total natural gas import
- boilerHeatProd: heat generation of a boiler (via calorific meter)
Om de siteverbruiken te kennen werk je met een 'metric' die 'meterdata' aggregeert:
- siteElecCons = siteElecCons or (sum(ElecProd) + gridElecNet or (gridElecImport - gridElecExport))
