Starting today, if you are using Tandem Diabetes Care’s t:slim X2 pump with Control-IQ™ technology, you can view all of your data, including all of the unique Control-IQ technology events in your Tidepool account.
In this blog post, we’ll be breaking down what you need to know about uploading data from your Tandem pump to your Tidepool account, what your Control-IQ technology data looks like in Tidepool Web, and what clinicians need to know about this update. As you’re learning about these new updates, please keep in mind that with Tidepool, it’s your data, and you’re in control. You can use Tidepool to view, share with other Tidepool users like your clinician, and donate your anonymized device data as you see fit.
Additionally, on June 3, Abby Bayer-Pratt RN, BSN, CDCES and I hosted a webinar featuring all of our Control-IQ technology-focused updates and answering questions from the Tidepool community. You can watch the archived recording of that webinar on our YouTube page.
Using Tidepool Uploader and the micro-USB cable that comes with your Tandem pump, you can upload all of your data — insulin, carbs, and CGM (continuous glucose monitor) readings — from your pump to your free, cloud-based Tidepool account.
Please make sure you are using Tidepool Uploader version 2.36.3 or newer to upload your Control-IQ technology data. If you’re new to Tidepool, you can download the latest version of Tidepool Uploader at tidepool.org/download. If you already have Tidepool Uploader installed, you will be prompted to update to the latest version the next time you launch Tidepool Uploader.
Your first upload may take a little longer than normal, but after that future uploads will be much faster.
Once your upload is complete, you can click “See data” and be taken to Tidepool Web to see your data.
Using Tidepool Web, you’ll gain a better understanding of what Control-IQ technology is doing, and when it’s taking action. Let’s start with what you’ll see in the Basics View.
Within the Bolusing section, the “Calculator” filter will show you boluses that include a carb entry and a recommended bolus based on your profile settings.
To give you a sense for how active Control-IQ technology has been over a given time period, the “Automated” filter will show you automatic correction boluses administered by Control-IQ technology.
You can use the “Manual” filter to highlight boluses that you administered without including a carb entry.
The Basals section now includes an “Automation Exited” filter to highlight the number of times Control-IQ technology was turned off for one reason or another. Things like site and sensor changes, as well as a loss of CGM connectivity are examples of times when Control-IQ technology would be off.
The Summary Statistics on the right-hand side of the Basics View also detail some of the unique aspects of using Control-IQ technology.
First, let’s cover the standard widgets on this sidebar. Starting from the top, you can review your time in range statistics based on your target glucose range. The default range is 70-180 mg/dL, but you can change that in your profile settings. (If you’re using Control-IQ technology in Canada, you can change your display units to mmol/L in your profile settings, too).
Beneath your average glucose reading (based on CGM data) and your sensor usage percentage, you’ll see your basal/bolus ratio broken down by percent and units of insulin.
At the bottom you’ll find Average Daily Carbs entered into your insulin pump, and two summary calculations based on your CGM data: Glucose Management Indicator (GMI) is an approximation of your A1c, and your Coefficient of Variation (CV) is an indication of how far apart your CGM readings are from each other.
New to the Summary Statistics sidebar, and unique for Control-IQ technology, are Average Daily Time in Automation, a quick indicator of how long you’re running Control-IQ technology over the reporting period you’ve chosen, and Average Daily Time in Activity, detailing on average how much time is spent in Sleep and Exercise Activity.
As a reminder, the Basics View defaults to the most recent 14 days of data, but if you want to see your summary data over a longer period of time, like 30 or even 90 days, click the calendar icon at the top of the page and expand your data window.
The Daily View is your best friend if you want to get a finer understanding of what Control-IQ technology is doing.
Your Dexcom G6 CGM data is displayed in the Blood Glucose section at the top of the Daily View. All of your boluses and carb entries will be shown below.
Any time you enter carbs into your pump for a bolus, you’ll see that represented by a yellow circle with the carb entry included. Hovering over that bolus will show you additional details, including your profile pump settings at the time of that bolus delivery.
Automatic correction boluses have a slightly different color, and you can see the precise time and amount administered by Control-IQ technology by hovering over any of those darker teal automatic bolus indicators.
The Basal Rates section shows off your automated basal. Hovering over any portion of the graph will show you how much basal insulin was delivered.
Any time you use Exercise Activity, an “E” flag will appear. You can hover over that “E” to see how long you spent using Exercise Activity. Similarly, Sleep Activity is denoted by a “Z” flag and you can hover over that flag to see how long Sleep Activity was running for that segment.
On the right side, you’ll see some familiar summary statistics: Time in Range, Average Glucose, and Total Insulin delivered (including the basal and bolus breakdowns). Beneath that, Time in Automation stat will be a quick indicator of how much time was spent without Control-IQ technology running, and you can see just how much time was spent using Sleep and Exercise Activity for a given 24-hour period in the “Time in Activity” stat.
Finally, you’ll see Total Carbs entered into your insulin pump, as well as a calculation of Standard Deviation and Coefficient of Variation for your CGM data for those 24-hours.
The Trends View focuses on your CGM data over a 1, 2, or 4 week period. As you scroll back in time or adjust the different days of the week you want to review (like just weekends), you’ll see the same “Time in Activity” summary statistics calculated for the data you’re viewing.
James Jellyfish's data, for example, shows some opportunities to adjust how and when he's bolusing for lunch.

If you’re coming to Tidepool for the first time and you want to see your Control-IQ technology data in Tidepool, you can get started by creating your free Tidepool account at tidepool.org/signup.
If you’ve been using Tidepool with your t:slim X2 pump with Control-IQ technology for a while, please double-check that you’ve updated to the latest version of Tidepool Uploader to make sure you take advantage of this newest update.
If you’re a clinician already using Tidepool, please coordinate with your IT team to update to version 2.36.3 as this is the minimum version required to use your computers in your clinic to upload Control-IQ technology data from your patients’ t:slim X2 insulin pumps. As soon as your patients using Control-IQ technology upload their data, you’ll be able to see these new and updated reports during your scheduled appointments.
And if you’re a clinician considering Tidepool to improve your team’s workflow to view data from t:slim X2 pumps with Control-IQ technology and more than 50 other supported devices including pumps from Insulet and Medtronic all in one place, send a message to clincs@tidepool.org to speak with our Clinic Success Team and learn more about how Tidepool can work with you and your patients.
