🚀 Quick Guide: How to Install Watchfaces

Each watchface comes as a compiled, ready-to-install binary package (.pbw) optimized for Pebble Gabbro (260×260). Dials can be customized or switched directly on your watch.

METHOD 1

Official Pebble / Rebble App

Download the .pbw file onto your smartphone (Android or iOS). Tap the downloaded file and select "Open with Pebble". The Pebble app will instantly transfer and install the watchface over Bluetooth.

METHOD 2

Gadgetbridge (Open Source Android)

On devices running Gadgetbridge, share the downloaded .pbw directly to Gadgetbridge or open it from your file manager. Tap "Install" to flash the watchface.

METHOD 3

Pebble SDK / CLI Emulator

For developers with the Pebble / Rebble SDK installed on Mac or Linux:

pebble install --emulator gabbro Rolex.pbw

pebble install --phone 192.168.1.XX Watchface.pbw

CGM GLUCOSE

Gluroo / Nightscout Setup

Watchfaces with continuous glucose monitoring sync in the background via PebbleKit JS. Open the watchface Clay Settings in the Pebble mobile app and enter your Gluroo URL and token to receive real-time blood glucose and trend arrows.

📖 View detailed guide: How to get your Gluroo URL & Security Token →

STEP 1

Connect your Continuous Glucose Monitor (CGM) to Gluroo

Gluroo works as a cloud hub that receives blood glucose readings from your sensor and hosts a free, private Nightscout server instance for your smartwatch.

🔹 FreeStyle Libre 2 & 3 (via LibreLinkUp):

Abbott does not allow direct third-party connections to the primary FreeStyle LibreLink app. The official method approved by Abbott is via LibreLinkUp:

Download the LibreLinkUp app or visit the LibreLinkUp website and register an account using a secondary email address (different from your primary FreeStyle LibreLink account).
Open your primary FreeStyle LibreLink app on your smartphone, tap the menu ☰ → Connected Apps → LibreLinkUp → Add Connection, and invite the secondary email. Accept the sharing permissions.
Open the Gluroo app on your smartphone. Tap the Settings ⚙️ icon (top right) → CGM Data Sources → select FreeStyle Libre / LibreLinkUp.
Enter the secondary email, password, and your geographical region (e.g., Europe or US). Within 1–2 minutes, Gluroo will begin streaming glucose data.

🔹 Dexcom (G6 / G7 / ONE / ONE+):

Open Gluroo → Settings ⚙️ → CGM Data Sources → select Dexcom.
Log in with your Dexcom credentials (or activate Dexcom Share and use follower credentials). Select your server region (US or International / Outside US).

🔹 Juggluco / xDrip+ (Direct Bluetooth Streaming):

In your app settings, navigate to Nightscout Upload and enter your Gluroo Nightscout URL and Token obtained in Step 2.

STEP 2

Locate your Nightscout URL & Security Token in Gluroo

Gluroo automatically provisions a private cloud Nightscout instance for your account:

Open the Gluroo app on your iPhone or Android device.
Tap the Settings ⚙️ icon in the top right corner.
Tap Account or scroll down to the Nightscout Bridge / API Access section.
Locate your two critical credentials:

1. Nightscout Host / URL (Link):

Has the format https://<subdomain>.ns.gluroo.com:<port>. Example:

https://a1b2.ns.gluroo.com:12345

⚠️ CRITICAL: Do not omit the colon and the trailing port number (e.g. :12345). Without the port, connection attempts from your watch will time out.

2. Security Token / API Secret:

A unique UUID security token protecting your glucose data. Example:

a1b2c3d4-e5f6-7a8b-9c0d-1e2f3a4b5c6d

💡 Tip: Tap directly on the token in the Gluroo app to copy it cleanly to your clipboard without trailing spaces.

STEP 3

Test your URL & Token in any Web Browser (Quick Verification)

Before entering the credentials on your watch, verify that your Gluroo Nightscout endpoint is actively streaming by pasting this URL into Safari, Chrome, or Firefox on your phone or PC:

https://<subdomain>.ns.gluroo.com:<port>/api/v1/entries.json?token=<YOUR_TOKEN>&count=2

If configured correctly, the browser will output a JSON snippet with your current sgv (blood glucose in mg/dL), timestamp, and direction trend arrow.

STEP 4

Enter your Credentials into your Pebble Watchface

Open the official Pebble app (or Rebble / Gadgetbridge) on your smartphone.
Navigate to your installed watchfaces and tap the Settings ⚙️ gear icon next to your CGM-compatible watchface (e.g. Origami, Breitling Airwolf, Casio Pro Trek, Chrono Titanium).
The Clay web configuration screen will open:
- Paste your full Gluroo / Nightscout URL into the URL field.
- Paste your Security Token into the API Secret / Token field.
- Choose your preferred blood glucose display units (mg/dL or mmol/L).
- Optionally customize vibration alerts for high and low thresholds.
Tap Save. In a few seconds, your Pebble watch will connect and display your live glucose reading and trend arrow, updating automatically every minute in the background.

FAQS

Troubleshooting & Common Errors

⚠️ HTTP 401 / Unauthorized Error

The Security Token was pasted with an accidental space at the beginning or end, or a character is missing. Copy it again directly from Gluroo Settings.

⚠️ Timeout (0) or No Connection

The port number was omitted in the URL. Ensure the address looks like https://xxxx.ns.gluroo.com:PORT (including :PORT).

⚠️ Glucose freezes after a few minutes

Your smartphone's battery saver put LibreLinkUp or Gluroo to sleep. In phone settings, set LibreLinkUp, Gluroo, and the Pebble app to Unrestricted / No Battery Optimization.

⚠️ Readings delayed by ~5 minutes

LibreLinkUp pushes updates to the cloud approximately every 1 to 5 minutes. This is standard Abbott cloud behavior.
