openaps utility belt

These are the core utilities needed to develop a self-built open source
artificial pancreas.

This is part of a series of tools to support a self-driven DIY
implementation based on the OpenAPS reference design. The tools may be
categorized as monitor (collecting data about environment, and
operational status of devices and/or aggregating as much data as is
relevant into one place), predict (make predictions about what should
happen next), or control (enacting changes, and feeding more data back
into the monitor).

By proceeding using these tools or any piece within, you agree to the
copyright (see LICENSE.txt for more information) and release any
contributors from liability.

Check out the OpenAPS documentation to help get you started.

Note: This is intended to be a set of tools to support a self-driven DIY
implementation and any person choosing to use these tools is solely
responsible for testing and implement these tools independently or
together as a system. The DIY part of OpenAPS is important.
While formal training or experience as an engineer or a developer is not required, what is required is a growth
mindset to learn what are essentially “building blocks” to implement an
OpenAPS instance. This is not a “set and forget” system; it requires
diligent and consistent testing and monitoring to ensure each piece of
the system is monitoring, predicting, and performing as desired. The
performance and quality of your system lies solely with you.

Additionally, this community of contributors believes in “paying it
forward”, and individuals who are implementing these tools are asked to
contribute by asking questions, helping improve documentation, and
contribute in other ways.

This is not an artificial pancreas, but rather tools which independently allow:

• monitor - Collect data about environment, and operational status of devices.
  Aggregate as much data relevant to therapy as possible into one place.
  We propose a tool, openaps-use as a proof of concept.

• predict - Can make predictions about what should happen next.

• control - Can enact changes in the world: emails, placing phone calls, SMS,
  issuing commands to pumps.

Install

There are two ways to install openaps, from source, and as a python package via
setuptools.

The following apt-get dependencies are required (they can be installed through
variety of means, in debian/ubuntu and apt based systems the following packages
are recommended/required:

sudo apt-get install python python-dev python-setuptools python-software-properties python-numpy

From source

To install from source
clone this repo, and issue:

sudo python setup.py develop

From pypi

To install from pypi:

sudo pip install -U openaps

This installs openaps system wide.
Do not use openaps commands in the the openaps repo. Only use the
openaps directory for hacking on the core library, or for managing
upgrades through git. Running openaps inside of the openaps
source directory will error in the best case, and mess up your
openaps install in the worst case.

Updating

sudo easy_install -ZU openaps

Utilities for developing an artificial pancreas system.
openaps helps you manage and structure reports for various devices.

All of the device and report add and show commands modify
openaps.ini in the current working directory, which is assumed to be
a git repo explicitily dedicated to helping develop and configure a
DIY artificial pancreas system. This means openaps is an SDK for
an artificial pancreas system, not an artificial pancreas system.

See openaps init for setting up a brand new instance of your own
openaps, or see the notes below for details on how to convert an
existing git repo into an instance of openaps.

Common workflows:

openaps init
openaps device <cmd>
  
  Device commands allow you to match a device driver, with a name
  and a configuration.
  
  add     - add device config to `openaps.ini`
  remove  - remove device from `openaps.ini`
  show    - print device uri, list all by default

openaps use [--format <json,stdout,text>]
            [--output <filename>]
        <device>
        <use>
        [use-args...]

  For each device registered, the vendor implementation provides a
  number of uses.  This allows users to experiment with reports.

openaps report <cmd>

  Reports match a device use to a format and filename.

  add     - add report config to `openaps.ini`
  remove  - remove report from `openaps.ini`
  show    - print report uri, list all by default
  invoke  - run and save report in file

Init new openaps environment

Do not use openaps commands in the the openaps repo. Only use the
openaps directory for hacking on the core library, or for managing
upgrades through git. Instead change to a new directory, not managed
by git: cd ~/Documents.

Setup of new instance:

openaps init myopenaps    - this creates an instance of openaps in a new
                            directory, called myopenaps


cd myopenaps - change directory to root of new repo

A valid instance of openaps is a git repo with a file called
openaps.ini present.

openaps will track configuration and some status information inside of
openaps.ini.

Init existing git repo as openaps-environment

If you already have a git repo which you would like to
become a valid openaps environent, in the root of your repo, run:

touch openaps.ini
git add openaps.ini
git commit -avm 'init openaps'

Now, wth a valid openaps environment, you can register devices for
use. A device is implemented by a vendor. openaps provides a
modular, language and process independent environment for creating
vendors and devices.

Managing devices

To register devices for use, see openaps device commands:

openaps device -h
openaps device add <name> <vendor> [opts...]
eg:
# register a medtronic device named pump
openaps device add pump medtronic 665455
# register a dexcom device named cgm
openaps device add cgm dexcom

Using devices

Now that devices are known, and we have a variety of commands
available. We can explore how to produce reports by using devices
with the openaps use command:

openaps use <device-name> <use-name> [opts]

openaps use commands can only be used after devices have been added to
the openaps.ini config using openaps device add.
Eg:

openaps use pump -h        - show available commands for the
                             device known as "pump"
openaps use pump iter_pump 100 - get last 100 pump history records
                             from the device called pump
openaps use cgm -h         - show available commands for the
                             device known as "cgm"
openaps use cgm glucose

Save reports

After experimenting with openaps use commands, users can save reports
using the openaps report commands.
openaps report commands map openaps use commands to filenames:

openaps report add

Adding a report means configuring a use command with a format and a
output, most commonly, a filename is used as the output.

openaps report add <report-name> <report-formatter> <device> <use> [opts]

# add a report, saved in a file called pump-history.json, which is
# JSON format, from device pump using use iter_pump.
openaps report add pump-history.json JSON pump iter_pump 100

# add a report, saved in a file called glucose.json, which is
# JSON format, from device cgm using use glucose.
openaps report add glucose.json JSON cgm glucose

invoke reports to run and save the results of the use

openaps report invoke

Invoking a report means running a use command according to it’s
configuration.

# invoke the report to create glucose.json
openaps report invoke glucose.json

# invoke the report to create pump-history.json
openaps report invoke pump-history.json

All commands support tab completion, and -h help options to help
explore the live help system.

Some commands like read_glucose_data, read_history_data take a
page parameter, describing which page to fetch.

Some commands like bolus, set_temp_basal, take an input
parameter which may be - for stdin or a filename containing a json
data structure which represents the request.

All commands support -h and --help output.
