Upload Loop to Nightscout Pro

Use this guide when Loop already receives your CGM data and is configured for your supported pump/sensor combination. It applies to the upload service, including the old Dexcom/Libre guide choices; it does not establish direct Libre compatibility or configure therapy.

Connect the service

1. Copy the full HTTPS site URL and API Secret from your Pro Site Settings.
2. In Loop, open Settings, scroll to Services, and choose Add Service.
3. Select Nightscout. Enter the site URL in URL and the API Secret in its separate field. Do not use your Pro account password or an xDrip Base URL.
4. Tap Login. Check that the service was added without an error.
5. Compare a new reading in Loop and Nightscout. Check an existing treatment and the relevant uploaded status separately.

Do not enable another glucose bridge when Loop is already the intended uploader.

Connection error or stale profile

Confirm the exact site opens in a browser and copy the error text. Verify you used the current API Secret and included the full regional hostname. A certificate or host error is not proof of a password problem; keep HTTPS enabled.

If the app reports a successful service connection but records remain absent, provide the Loop version, iOS version, build method and last successful upload time. For ordinary missing uploads, do not change therapy to force a refresh. If a remote command instead returns HTTP 500: Loop notification failed: Could not find LoopSettings in Profile., first enable an override directly in the Loop app. This sends the profile data and device token to Nightscout. See the specific LoopSettings solution.

Remote commands need separate configuration and verification. Ordinary upload success does not prove command delivery.
