guhrli - simple cgm monitor

Features

• Display latest CGM reading from either:
  • Nightscout
  • Tomato
  • xDrip+ (android only)
• Clock colour changes with reading
  • In range -> green
  • High values -> orange/red
  • Low values -> light/dark blue
• Minimal configuration
  • Units + alarm thresholds are read from source
• Second time zone
  • Toggle on/off and set the offset in the settings

Getting started

1. Install the app from the Fitbit Gallery
2. Select your data source from the app Settings inside the Fitbit app
   1. If using Nightscout, enter your URL in the settings. Don't include /api/v1
3. That's it! You should see readings appear in the corner of your watch. If not, see troubleshooting

Differences Between Sources

• High/low thresholds: Due to the different levels of detail available in each API, each source has slightly different behavior for thresholds. Nightscout provides 4 levels (urgent low/low/high/urgent high) based on the user's settings. xDrip+ provides just 2 (low/high), and so only 3 different colours will be used in the watch. Tomato provides no alarm information, so 4 hardcoded default thresholds are used.
• Offline mode: Only xDrip+ supports offline mode, meaning that results will still be updated on the watch when the phone has no internet connection. A bluetooth connection between the phone and the watch is always needed.

Troubleshooting

🚧 coming soon 🚧

In the meantime, you can contact me via the app page in the Fitbit gallery.

Development

Building + Installing

• run npm install
• make sure watch is connected to the Developer Bridge
• start fitbit console with npx fitbit
• build: fitbit$ build (see below about building for production)
• install: fitbit$ install

Building for Production

When creating a build for release, all tests need to run and pass. Therefore, this build should only be done using the build script:

    npm run build

which runs the tests before building the app. The resulting build is placed in the build/ directory.
