trndi-multi - Everyone's glucose on one screen

Features

One window, every account

👥

One Tile per Person

Every account gets a tile: name, value, trend arrow, delta and the time of the reading. Add them right here, or use the ones already set up in Trndi's multi-user mode.

🎨

Colour by Range

Green in range, red below the low limit, red-orange above the high one, amber and blue for a personal target band — the same meaning as in Trndi, using each person's own thresholds.

📈

Sparkline

The last three hours drawn under the value, with the high and low limits as lines, so a slow drift is visible before it becomes an alarm.

⏳

Old Readings Look Old

A reading that has aged past two sensor intervals dims its tile and is marked stale with its age, so a silent sensor is never mistaken for a steady one.

🧵

Independent Polling

Each account is fetched on its own thread, timed to land just after the next reading is due. A slow login on one never delays the others.

🖥️

Wall Display Ready

Everything scales with the window and the grid picks the layout that gives the biggest tiles. --kiosk goes full screen, hides the pointer and keeps the machine and screen awake, on Linux, macOS and Windows.

🔗

Shares Trndi's Settings

Built on the same API and platform layer as the desktop app, and on the same settings store. Accounts added in either program show up in both, and colours and thresholds set in Trndi are honoured here.

Linux Notes

The binary uses the Qt6 LCL, so install the bindings and libcurl first: libqt6pas6 on Debian and Ubuntu, qt6pas on Fedora. Then mark it executable (chmod +x trndi-multi-linux-amd64) and run it. Other widgetsets build from source with make WIDGETSET=gtk2. Build instructions →

Building

Needs Lazarus (lazbuild) and libcurl. Clone with the submodule and run make:

git clone --recurse-submodules https://github.com/slicke/trndi-multi.git
cd trndi-multi
make              # bin/trndi-multi
sudo make install # optional

Windows builds with .\make.ps1, macOS with gmake. Full instructions →

Setup

Accounts are shared with Trndi

1️⃣ Add people

Right-click the window and choose Accounts: one tab per person with a nickname, the system (Nightscout, Dexcom and so on), its login and the unit. The + tab adds an account. Already using Trndi's multi-user mode? Those accounts are there already. Multi-user guide →

2️⃣ Save

The tiles reload on the spot: every account with a backend, the default account first, the nickname as the tile's title. The same accounts are now in Trndi too.

Keys

F5          refetch every account now
F11         full screen (Esc leaves it)
Q           quit
Right-click accounts, refresh, full screen, quit (not in kiosk mode)

trndi-multi --fullscreen   start full screen
trndi-multi --kiosk        wall display: full screen, pointer hidden, Esc ignored,
                           machine and screen kept awake while it runs

💡 Values are shown in the first account's unit, so a wall with both mmol/L and mg/dL accounts still reads as one thing. Account colours and thresholds, alarms, extensions and the Web API stay in Trndi itself.
