Uploading your Tandem insulin pump

⚠️Important Note: If your pump gets restarted or powered off for any reason such as a battery failure, pump error, or software update for G7 or Libre 3 Plus support, the data from before your pump restart cannot be uploaded. Please upload your pump before your pump gets powered off to ensure you can upload all your pump data. ⚠️

This article assumes you have:

  • A Tidepool account — you can create one for free at tidepool.org/signup.
  • Installed the latest version of Tidepool Uploader — you can download the latest version at tidepool.org/uploader.
  • A Tandem insulin pump — Tidepool is compatible with t:slim, t:slim G4, t:flex, and t:slim X2 insulin pumps.
  • A micro-USB cable — this is a common cable and one should have come with your pump.
    If you receive an error message, "Error: Hmm, your device doesn't appear to be connected" please try another micro-USB cable that you are using is capable of carrying data. (Many that come with devices can only be used to recharge).

4. Troubleshooting

If you upload your Tandem pump but are missing some of your pump and/or CGM data when viewing in Tidepool Web, we recommend you retry uploading with the "All data" option enabled in Tidepool Uploader. 

  • Open Tidepool Uploader and log in if not already logged in.
  • Left-click the Upload menu (not the button) and left-click All data.

  • Now connect the pump via micro-USB and click the Upload button in the main Tidepool Uploader window as seen in Step 2 of this guide.
  • This upload will take much longer as it is retrieving all the records from the pump and can take anywhere from 10-30 minutes, depending on the amount of data on the pump.
  • Once completed, log into Tidepool Web and you should now see the previously missing data.
