Setup

Initial Configuration¶

After you build LoopFollow the first time, you are asked a few questions (your initial choices can always be modified later):

• Calendar Access: if you want to allow LoopFollow to provide real-time updates to carplay using the Calendar, choose Allow Full Access
• Bluetooth Access: if you want to use an expired Dexcom sensor or a spare RileyLink device to keep LoopFollow running in the background while your phone is locked, choose Allow
• Notifications: if you want LoopFollow to notify you for any of your alarms or if LoopFollow stops working, choose Allow

You will then be presented with a home screen as shown below.

Setup Your Data Source¶

Tap on the "Setup Nightscout" button or "Setup Dexcom Share" button to enter your credentials for your preferred service.

For more information about how to configure your data source, refer to these sections:

• Setup Nightscout
• Setup Dexcom

Once a Data Source is entered, you have access to a variety of LoopFollow features.

The default settings are a fine place to start. As you learn to use LoopFollow, you can explore the adjustable Settings and Features.

Home¶

The home screen provides a dashboard of important information.

• Supports Glucose display when Dexcom is available but Nightscout is not
• Supports Information Display from Loop and Trio when Nightscout Site is provided
  • Loop & Trio: common features like status, basal, bolus, carbs and eventual glucose forecast
  • Loop: Loop specific features like Profile Name, remote control
  • Trio: Trio specific features like Autosens, TDD, remote control (with Trio 0.5.x and newer)

Once you’ve configured your settings, your Home screen will look as beautiful as the example below!

Toolbar¶

The toolbar (tab bar) at the bottom of the Home and Menu screens is configurable using Settings: Tab. Four icons are displayed at a time — choose from the options below. The features that can be selected are:

Menu Screen¶

The following graphic shows the menu screen. The menu can always be reached using the right button of the toolbar on the Home and Menu screens.

• The features on this screen are described on the LoopFollowDocs Features page

• Support & Community are discussed on the LoopFollowDocs home page

Settings Screen¶

The Settings Screen is accessed by tapping on the Menu icon and selecting the Settings row.

• The Information Display and Remote rows are only available with Nightscout Credentials.

LoopFollow Data Source¶

Make sure you have access to the internet when filling out credentials.

You provide LoopFollow with information about the person you are following. At least one of these must be entered:

• Nightscout URL
• Dexcom Share credentials

Setup Nightscout¶

The graphic below shows the display when you tap on the Nightscout row. For more information about tokens, keep reading the details below the graphic.

When adding the Nightscout information to monitor, you can copy your Nightscout URL (including the token) from the Admin Tools in Nightscout. When pasted into LoopFollow URL row, the app will automatically extract and fill in both the URL and token.

The type of token depends on the type of remote control desired. The table below indicates the minimum token access for each type of remote control available with LoopFollow. When you enter your credentials, LoopFollow tries to reach the site and then provides the status.

For a full summary of version requirements for Loop and Trio remote control, see Version Compatibility.

Setup Dexcom¶

The graphic below shows the display when you tap on the Dexcom row.

The Dexcom Share credentials are optional, but can be useful when the Nightscout URL is unavailable.

Settings Details¶

General¶

These settings are accessed through the General row in the Settings screen.

Graph¶

These settings are accessed through the Graph row in the Settings screen.

Information Display¶

These items can be chosen for display on the Home screen. A Nightscout Site is required and must be accessible or the table is blank.

A lower case loop is used to denote a closed-loop cycle for both Trio and Loop.

The user can modify which icons are displayed in the task bar at the bottom of the screen.

In the Settings screen, select Tab. Drag any of the options up or down to your preferred configuration.

Import/Export¶

When setting up LoopFollow for another caregiver that will use some or all of the same configuration settings, you can export or scan a QR code to transfer settings between phones.

• Nightscout Site and token
• Dexcom Share
• Remote Configuration
• Alarms

Export Settings¶

To export settings, select one of the options for

• Export Nightscout Settings
• Export Dexcom Share Settings
• Export Remote Settings
• Export Alarm Settings

Export Nightscout Settings, Export Dexcom Share Settings and Export Remote Settings will show a QR code directly that you can scan with the receiving phone.

Export Alarm Settings will let you select up to 5 alarms at a time to export. If you re-enter the export screen after a successful export, it will mark the exported alarms so that you can export more alarms if needed

Import Settings¶

On the phone that will receive the settings from the QR code, choose the option: "Scan QR Code to Import Settings"

The first time you import settings with LoopFollow, you will be required to give permission to use the camera. Once permission is granted, hold the importing phone to view the QR code presented by the exporting phone.

When the QR code is accepted, you will see a screen indicating what type of settings is being imported. You will be warned that if you accept the import, your current settings will be overwritten.

Note the QR code for alarms may be slow to import. Just move the phone closer and further away until the code is accepted.

Remote¶

Detailed instructions for configuring a phone for remote control are found on the Remote Control Overview page.

If you are configuring a second device and already have one device configured for remote control, be sure to review:

• Export Remote Settings with QR Code
• Import from QR Code

Alarms¶

The Alarms settings allow you to control the behavior of all active alarms. Individual alarms are selected and configured with the Alarms Feature.

• One nice feature you may want to enable is the Volume Buttons Snooze Alarms option.

Calendar¶

The calendar entry used to update on the watch in real time, but with iOS 18, the update rate has been throttled. It is still useful for Carplay.

Contact¶

The Contact image trick added with v2.2.8 currently works to provide real-time updates on an Apple Watch.

For more detailed instructions, see Real-Time Watch Updates using Contact
