Connect Nightscout

Start with a reachable Nightscout site that is receiving current readings.

Glucose Display is a secondary display. Follow your CGM manufacturer’s instructions and use your primary CGM app/device for treatment decisions and primary alerts.

What you need

  • Your Nightscout site’s base URL, such as https://your-site.example.com.
  • A working uploader or bridge that keeps the site’s readings current.
  • Internet access from the display to that site.

Step-by-step setup

  1. Open the Nightscout site in a browser and check the timestamp of its newest reading.
  2. On the display, choose Connect to Nightscout.
  3. Enter the site’s base URL. Do not append /api/v1 or paste a link containing ?token=.
  4. If the site requires authentication, enter its access credential in the separate token field on the display. Credential compatibility depends on your Nightscout configuration and app version; contact support if authentication fails.
  5. Add an optional display name and select Connect to Nightscout. Keep the upstream uploader running.

Common problems

  • 401 / 403: check authentication and permissions with the person who manages your Nightscout site. Do not send the credential to support.
  • No data: check the base URL, the site’s newest reading and whether the display’s network can reach the host.
  • Intermittent failures: check hosting availability, rate limits and network access.

Should I add the API endpoint to the URL?

No. Glucose Display builds its readings request from the base URL. Adding /api/v1 can create the wrong request path.

Troubleshooting secondary displays

Still stuck?

Contact support with your source, country/region, app version, exact error, phone OS and network type. A screenshot with personal details hidden can help. Do not send passwords, access tokens or API secrets.
