Eversense CGM

🚧 Documentation Under Construction 🚧

This page is under development.

The addition of the Eversense CGM to iOS Open-Source Automated Insulin Delivery systems is new.

Please review the EversenseKit Issues page for open issues reported for the EversenseKit CGM Manager.

Testing Eversense with the Loop App

  • The branch needed to get Eversense in Loop is: feat/eversense

    • This branch is subject to rapid updates
    • This branch provides support for Dana and Medtrum along with the Eversense CGM

  • Please refer to the zulipchat Loop-dev development channel before building this branch.

Eversense 365 Screen

The user interface for the 365 sensor is shown below.

Calibration and Battery Indicators

  • Once stabilized, the Eversense Transmitter requires weekly calibrations
    • The Eversense will stop reporting glucose readings if the required calibration is more than 24 hours late
  • The Eversense Transmitter requires charging every 2 to 3 days

The calibration status and battery level is highlighted at the top of the Eversense screen.

eversense calibration status

  • The left screenshot shows an orange line indicating a calibration is due in less than 24 hours
  • The right screenshot is after calibration

Loop Main Screen

When calibration required is within 24 hours, the orange line is echoed on the top of the Loop main screen under the CGM icon to serve as a reminder to calibrate soon.

Once the calibration is due, there is a 24-hour grace period before transmitter stops reporting glucose values. During that time, the "Next calibration in" line is red. This red line is also echoed on the top of the Loop main screen under the CGM icon.

As usual for calibrating a CGM, choose a time when glucose is stable to measure glucose with a finger-stick and enter the value into the user interface. The calibration takes 15 minutes to process.
