Nightscout Introduction

Nightscout (NS) is an open-source, DIY project that allows real-time access to CGM data via a personal website, smartwatch viewers, or apps and widgets available for smartphones. Setting up a Nightscout web app is recommended to visualize your Trio closed loop.

Nightscout allows a user to upload CGM data from various sources to an online database and cloud computing service. The information is then processed and displayed visually as a graph. Plugins also allow more information to be shown about Trio.

Even if you don't choose to share your Nightscout site with another person, it will be helpful for you to visualize what the loop is doing and what it's been doing, plus generate helpful reports for understanding your data.

For help making a Nightscout account, please see the OpenAPS documentation.

Trio Setup

To enable your nightscout connection, input your Nightscout URL, including the https:// and your API_SECRET. Select Allow uploads so Trio can share its predictions and settings with Nightscout.

Remote Caregivers and Missing Red Loop in Nightscout

Remote Caregivers and Missing Red Loop in Nightscout

Read this section if you are using Trio version 0.2.3 or earlier.

Why the “Red Loop” Indicator is Missing in Nightscout

When using Nightscout version 15.0.2 (and earlier), a caregiver looking at a Trio site will not see a “red loop” indication on Nightscout when the Trio phone is still getting glucose readings, but the Pod is disconnected (because of a communication issue or if it is deactivated). Even if the Trio phone clearly indicates the Pod issue, a remote viewer needs to know how to recognize this situation.

How to Recognize a Disconnected Pod in Nightscout

The caregiver will see predictions continue, but no sign of extra insulin delivered for rising glucose or withheld for falling glucose.

  • If it is a matter of communication problem (and the Pod is still active),
    then the Pod will return to scheduled basal rates when any active temporary basal duration ends.
  • If it is a matter of a Pod fault or removal without applying a new Pod,
    the rate of glucose increase may be pretty steep.

The signature for this situation when viewing the Nightscout display is either:

  1. 📈 rising glucose with no increase in temporary basal rates or application of manual bolus or SMB,
  2. 📉 or falling glucose with no temporary basal set to 0 U/hr.
