GlucoCube

A wall-mounted glucose dashboard for two or more people, on a Raspberry Pi with the official 7-inch touchscreen.

What it is

GlucoCube boots straight into the display, with no desktop environment, and shows each person's current glucose, trend, a three-hour history chart, a two-hour forecast, insulin on board, carbs on board and recent treatments. Flash the ready-made image, boot the Pi, and follow the QR codes on screen.

Each person's data arrives their own way: pushed from Trio or any Nightscout uploader, since the Pi speaks a minimal Nightscout v1 API with one port per person; pulled from Tidepool for the twiist system; or pulled from an existing Nightscout site.

It started life as SugarCube, and version 2 renamed it. A 1.x device needs its card re-flashed to move up, and the README explains why the old updater cannot make the jump.

What it does

A two-hour forecast with a confidence band: the AID system's own prediction when it has one, otherwise an oref0-style model using the person's therapy settings.
The same dashboard in any browser, with settings and a sync log managed from a phone. No SSH after install.
Guided setup from a phone: Wi-Fi, time zone, who it is for, and where each person's data comes from, one question per screen. With no network it opens its own setup hotspot.
Touch controls for day and night, and a QR code that opens settings already signed in.
Self-updates from GitHub releases on a standard or beta channel; a release marked force-update installs itself at the next check.
A printable OpenSCAD enclosure for the 7-inch display module, designed by Sarah Sabanis.

Part of the same system

One loop, one store, one wall

GlucoLoop runs the loop and writes. GlucoCore keeps everything once. GlucoCube reads it back and puts it where the household can see it.
