Glucometer Utilities

This repository includes a command line utility to interact with a number of blood sugar meters (glucometer) models from various manufacturers.

While support varies by device, the actions that may be available are as follows:

  • info shows the model, serial number, date and time, and configured glucose unit of the device.
  • dump export the recorded blood sugar or β-ketone readings from the device in comma-separated values format.
  • datetime reads or updates the date and time of the device clock.
  • zero deletes all the recorded readings (only implemented for few devices).

Example Usage

Most of the drivers require optional dependencies, and those are listed in the table below. If you do not want to install the dependencies manually, you should be able to set this up using virtualenv and pip:

$ python3 -m venv $(pwd)/glucometerutils-venv
$ . glucometerutils-venv/bin/activate
(glucometerutils-venv) $ DRIVER=myglucometer-driver  # see table below
(glucometerutils-venv) $ pip install "git+https://github.com/Flameeyes/glucometerutils.git#egg=project[${DRIVER}]"
(glucometerutils-venv) $ glucometer --driver ${DRIVER} help

Supported devices

Please see the following table for the driver for each device that is known and supported.

† Untested. ‡ Optional dependency on Linux; required on other operating systems.

To identify the supported features for each of the driver, query the help action:

glucometer.py --driver fslibre help

If you have knowledge of a protocol of a glucometer you would have supported, please provide a reference, possibly by writing a specification and contribute it to https://github.com/Flameeyes/glucometer-protocols/.

Dump format

The dump action by default will output CSV-compatible format, with the following fields:

  • date and time;
  • meter reading value;
  • before/after meal information, if known;
  • comment provided with the reading, if any.

Meal and comment information is provided by the meters supporting the information. In the future, meal information could be guessed based on the time of the reading.

The unit format used by the dump by default matches what the meter reports as its display unit, which might differ from the one used by the meter for internal representation and wire protocol. You can override the display unit with --unit.

Development

The tool is being written keeping in mind that different glucometers, even if they are all from the same manufacturer, will use different protocols.

If you want to contribute code, please note that the target language is Python 3.4, and that the style to follow is for the most part PEP8 compatible.
