Connect an eligible Medtronic setup to your hosted Nightscout site through CareLink and Pro Connect. First confirm that CareLink receives live data, then authenticate and check that fresh readings reach Nightscout.

Check your Medtronic and CareLink setup

Record your pump model, sensor model, source phone app and country. The supported route depends on that whole combination. A CareLink report uploaded from a computer does not by itself prove that the live data needed by Pro Connect is available.

For MiniMed 780G setups using Guardian, Simplera or Instinct, use the CareLink route appropriate to your system. The sensor manufacturer's name alone does not select a connection. See the device and data compatibility guide for scope and limits.

For an eligible MiniMed Mobile setup, check the manufacturer's Sync to CareLink setting and confirm that the intended Care Partner can see current data. Follow Medtronic's instructions for your app and country.

Connect CareLink with Pro Connect

If you do not yet have a hosted site, follow account and site setup first. Your Pro account password, Nightscout API Secret and CareLink credentials are separate.

Prepare a dedicated Care Partner account

Use a separate Medtronic Care Partner follower account linked to the CareLink account that receives your device data. Use this dedicated follower only for Pro Connect, rather than signing in with your main CareLink account.

Other sign-ins can invalidate the dedicated account's session, and multi-factor authentication challenges can interrupt automatic reauthentication. Keep MFA enabled on your main CareLink account. Read the dedicated-account requirements in the current signed-in CareLink setup guide before connecting.

Authenticate in the secure browser

  1. Sign in to your Nightscout Pro account, open the relevant site's Site Settings and expand PRO CONNECT.
  2. Choose the connection source: Source → Medtronic CareLink. Check the connection timezone: Timezone.
  3. Start CareLink sign-in: Authenticate CareLink. Keep the original Pro tab open and allow the secure browser window to open.
  4. Sign in on the official Medtronic CareLink page with the dedicated follower account and complete any challenge shown.
  5. Let Pro Connect detect the successful redirect and save the connection. Complete any highlighted required fields, then select SAVE PRO CONNECT if requested.

The normal secure-browser method does not require Developer Tools or copying a redirect URL. If it cannot complete, the Use the manual redirect method option is documented in the signed-in guide. An authorization redirect contains a one-use code: paste it only into the signed-in Pro Connect field, never into a support message or public screenshot.

Confirm fresh readings and troubleshoot gaps

Allow Pro Connect to start, then compare a new CareLink reading’s value and timestamp with Nightscout. Typical end-to-end delay is around 5–20 minutes and depends on upstream delivery. Check available pump event records separately; a full Nightscout profile or every treatment record type is not promised.

When data does not arrive, open Pro Connect Logs. Saving the form or seeing the Nightscout website load is not a successful data check.

CareLink has old or missing data

Check the source app, its internet connection, cloud syncing and the Care Partner link first. Pro Connect cannot retrieve readings that have not reached the live source. Repeating authentication cannot repair an upstream data gap or add an unsupported record type.

Login errors or repeated disconnections

If the secure browser does not open, check pop-up permissions. If it closes before setup completes, reopen it and keep both Pro tabs open during sign-in.

Reauthenticate when the logs identify expired or rejected authentication. If the same failure returns, check whether the dedicated account was used elsewhere or whether MFA requires a manual challenge. Send support the error and time rather than repeating the whole login process. Check Timezone if readings appear time-shifted.

Existing uploaders and older pumps

If xDrip+ already receives the current Medtronic readings you need, follow the xDrip+ Nightscout upload guide. This does not establish support for a new sensor, pump firmware or phone.

Older 600-series USB/OTG uploader arrangements and Guardian Monitor have separate hardware and app requirements. They are not the default Pro Connect setup. Ask support to check the exact route before buying equipment or replacing a working uploader. Choose one intended glucose uploader to avoid duplicates.

Next steps and help

Once fresh data is confirmed, keep your exact Nightscout site address and choose apps and displays with appropriate viewing permissions. Data and alerts can be delayed or interrupted; keep using your primary device and its alarms according to the manufacturer's instructions.

For setup help, email [email protected]. Include the pump and sensor models, source app, country, last reading time and redacted error. Do not send passwords, API secrets or CareLink redirects. Review hosting plans before starting a new subscription.
