libreview-to-nightscout

#WeAreNotWaiting to OWN our own medical data.

This uploads data from LibreView's exported CSV to a NightScout instance. See screenshots on this Twitter thread

Usage

Make sure you have Node.js v13.11.0 installed.

1. Login to Libreview and download your glucose data CSV. This requires a CAPTCHA, so it can't be automated (yet).

   

   Copy this data into the data/ directory of this repository.

2. Now we transform the data into a minimal format usable by NightScout and other tools. You must set your timezone through the TZ variable, and specify the path to the CSV with DATA_CSV.

TZ=Australia/Brisbane DATA_CSV=../data/DATA_FILENAME.csv node scripts/parse-librelink.js > data/libreview-parsed.json

3. Now we can upload the data. Specify your nightscout endpoint and API token (eg. rig-8abfe66c7). You will also have to specify the date from which you want data uploaded, as I'm not quite sure how/if Nightscout deduplicates data entries. Go to line 7 of upload-to-nightscout.js, and modify the from variable, which is a Unix timestamp. Then you can run:

NIGHTSCOUT_ENDPOINT_URL="" NIGHTSCOUT_API_TOKEN="" node ./scripts/upload-to-nightscout.js

You should see a large JSON blob of entries logged on success.

```js
[
{
    type: 'sgv',
    dateString: '2020-07-23T04:37:00.000Z',
    date: 1595479020000,
    sysTime: '2020-07-23T04:37:00.000Z',
    sgv: 219,
    noise: 1,
    utcOffset: 600
},
...
```

Bugs

• I've used this for LibreView AU. It assumes the mmol/L standard for BGL's, so it won't work for mg/dl out-of-the-box.
