CGM¶

This section allows you to choose your glucose data source. Most options are self-explanatory. For more information on compatible CGMs, please see the following link.

Step 1: Add CGM¶

The first step in setting up your continuous glucose monitor (CGM) on Trio is to tap the "Add CGM" button in the Devices Menu

Step 2: Select Your CGM¶

Select your CGM from the in-app menu and from the options below for step by step instructions. The links below will guide you through the connection instructions for your specific CGM:

• Dexcom G5 / G6 / ONE
• Dexcom G7 / ONE+
• Dexcom Share
• FreeStyle Libre 1 / 2 / 2 Plus
• FreeStyle Libre 3 / 3 Plus
• Eversense E3 / 365
• Glucose Simulator
• Nightscout as CGM
• xDrip4iOS

Dexcom G5 / G6 / ONE¶

Trio will intercept glucose readings between the transmitter and the Dexcom app. If you are using a Dexcom G5, G6, or ONE sensor, tap Configuration CGM to enter your transmitter's 6-digit ID. Dexcom Share Credentials are not necessary. When you switch transmitters, you must delete your current transmitter from Trio by tapping Configuration CGM, scrolling down, and tapping Delete CGM. Once you do this, you can add the new transmitter with its Transmitter ID.

Step 3 Enter your 6-digit Dexcom transmitter ID.

Step 4 Continue to Connect Watch OR return to New User Setup

Dexcom G7 / ONE+¶

As long as the Dexcom G7 or ONE+ app is installed on the same phone, Trio can intercept its glucose readings. When a new G7 or ONE+ sensor is paired to the Dexcom app, Trio will automatically start reading it.

Step 3 Tap "Continue" to use the G7/ONE+ as your CGM source

Step 4 Continue to Connect Watch OR return to New User Setup

Dexcom Share¶

FreeStyle Libre 1 / 2 / 2 Plus¶

This option can be used to pair a compatible Libre 1, Libre 2, or Libre 2 Plus sensor directly to Trio without going through a separate app like xDrip4iOS. In the in-app menu, it is listed as "FreeStyle Libre 1 / 2 / 2+". For Libre 3 and Libre 3 Plus sensors, see FreeStyle Libre 3 / 3 Plus instead.

Step 3 Tap "Libre 2 Direct" to use Libre 2 sensors or "Bluetooth Transmitters" to use Libre 1 sensors with a Miao Miao or other 3^rd party transmitter.

Step 4:Libre 2 Direct Tap "Pair Sensor" to connect your Libre 2/2+ sensor to Trio

Step 4:Bluetooth Transmitters (Libre 1) Select your 3^rd party transmitter from the list of found devices and tap "Save"

Step 5 Continue to Connect Watch OR return to New User Setup

FreeStyle Libre 3 / 3 Plus¶

Step 3 Apply a new sensor to the back of your upper arm. Tap "HOW TO APPLY A SENSOR" if you would like Trio to walk you through it, then tap "Next".

Step 4 Tap "Start pairing", then hold the back of your phone against the sensor and keep it still. Your phone vibrates once the sensor is paired. If the phone moves away too early, the scan fails and you can try again.

Step 5 Wait for Trio to finish pairing. Trio starts the sensor, connects to it over Bluetooth, and then receives a glucose reading every 5 minutes once warm-up is finished.

Step 6 Write down your Receiver ID, which you will find in the Debug Info section of the Libre 3 CGM settings page. The Receiver ID is the identifier the sensor remembers Trio by, and it is the only way to re-pair a sensor that is already running, for example after you delete the CGM from Trio or reinstall the app. To use it, tap "Recover existing sensor" on the pairing screen and enter the ID. When you re-pair a sensor that is already running, Trio shows "Stabilizing" for a while and does not display glucose readings the sensor itself flags as unreliable.

Step 7 Continue to Connect Watch OR return to New User Setup

Eversense E3 / 365¶

Step 3 Select whether you want to pair the Eversense E3 or the Eversense 365.

Step 4 (only for Eversense 365) Log in using your Eversense account. If you do not have an accunt or you forgot your password, the appropriate links are included in this step

Step 5 Now put your Eversense transmitter in pairing mode (done by tapping the button 3 times), and wait till your Serial Number shows up on screen. Click on the found transmitter, accept the pairing prompt (if show), and wait untill the pairing process is completed!

Step 6 Continue to Connect Watch OR return to New User Setup

Accu-Chek SmartGuide¶

Step 3 Wait a minute while Trio is scanning for your Accu-Chek SmartGuide

Step 4 Once Trio has found your Accu-Chek SmartGuide, it prompts you to confirm the Serial Number. This Serial Number can be found on the twist cap of your applicator.

Step 5 After you've confirmed the Serial Number, Trio will pair and configure your CGM. It might be the case that iOS asks for a Bluetooth pairing code, this code can be found at the top of the twist cap. After pairing, be sure to either never remove your CGM from the Bluetooth list or keep the twist cap/pincode somewhere safe.

Note you will need this pincode if you want to migrate to a new phone

Step 6 Continue to Connect Watch OR return to New User Setup

Glucose Simulator¶

Step 2 Continue to Connect Watch OR return to New User Setup

Nightscout as CGM¶

While using Nightscout as a CGM is an option, it should be avoided if possible because it does not keep Trio running in the background like other CGM options.

Step 2 Continue to Connect Watch OR return to New User Setup

xDrip4iOS¶

To use xDrip4iOS as a CGM source, you must build it yourself with the same Apple Developer account you used to build your Trio app. You cannot use Shuggah or a version distributed by someone else's TestFlight. Please see the following for instructions on how to build xDrip4iOS yourself: link

However, if you are using Dexcom G6 or ONE with xDrip4iOS, you can choose the Dexcom G6 option in Trio rather than xDrip4iOS, and Trio will intercept the glucose readings even if you're using Shuggah or someone else's TestFlight of xDrip4iOS.
