Coming from Loop

What to Expect After Install

  • Onboarding Wizard
    Trio will walk you through the initial setup of the app. Learn more in the New User Setup Guide.
  • User Interface
    You can find more about the Trio User Interface in this walk-through of the app.

  • Remote Commands & iOS Shortcuts
    Trigger actions like carb entry, bolus, overrides, or temporary targets remotely or through shortcut automation.

    • Use Loop Follow v4.0 or Later for remote commands
      Loop Follow is the companion app for Trio. More info at LoopFollowDocs.

    Note

    Loop Caregiver will not work with Trio

  • Bolus Calculator
    The Bolus Calculator in Trio offers simple dosing with clear breakdowns and safety logic.

  • In-App Statistics
    There are multiple statistics and graphs available in the Trio app. Click the link to learn more about the Statistics available in the app.

What to Expect in Your First 3 Hours

Here are some things to keep in mind after moving from Loop to Trio v0.5+ in the first 3 hours:

  • Onboarding Wizard
    Take this time to go through the Onboarding Wizard. Reference the New User Setup Guide or ask questions on Facebook or Discord if you have any questions.
  • Test Settings
    Your Loop settings may be a great starting point for Trio, but often times they need some adjustment. This is a great time to test your settings so you can start fresh on solid footing.
  • User Interface
    Use this time to learn the User Interface.

  • Dynamic ISF
    Dynamic ISF is disabled for the first 7 days.

    Dynamic ISF & Closed Loop

    Trio must be in Closed Loop for 7 days in order to enable Dynamic ISF.

  • Autosens
    Autosens will require 8–24 hours of data before it starts making adjustments. You may need to enter carbs and bolus during this time if you aren't already doing so.

    Initial Limitation with Autosens

    There's a long standing issue with Autosens where it will likely be stuck at 100% for the first 24 hours when there are carb entries or SMBs.

    • When carb entries or SMBs are not present, Autosens will kick in after 8 hours.
    • When carb entries or SMBs are present, Autosens will kick in after 24 hours.

    Whether or not to enable SMBs or enter carbs is a personal choice based on what you prioritize in your first 24 hours.

  • Nightscout Changes

    • You will need to update your Nightscout page to use Trio plugins rather than Loop plugins.
    • Replace loop with openaps in the variables ENABLE, SHOW_PLUGINS, and SHOW_FORECAST.
    • If you pay for Nightscout through a provider, please reach out to them to update your variables.

Do not use a pump or cgm simulator

  • Doing so will result in false data being stored and you will have to delete the app with all the data and reinstall before you can use it on a live pump.
  • This will also reset your 7-day waiting period for Dynamic ISF.

What to Expect After 24 Hours

A full day on Trio! Congratulations! Here's what to look for:

  • Autosens
    Autosens now has enough data to make adjustments.

  • Review & Test Settings
    This is a good time to review your last 24 hours of results to see if your core settings performed as expected. If you had unexpected challenges with your settings, look at how to test them over the next 7 days:

  • Review Dynamic ISF Documentation
    Review the documentation on Using Dynamic ISF in preparation for Day 7.

  • Meal Time Struggles
    Sometimes, users coming from Loop will notice stability during fasting periods, but meal times are more challenging than they were with Loop. This is due to a shift in algorithms. Loop is more carb-centric, causing users to place a heavy reliance upon their Carb Ratio over their ISF value. Trio is more reliant upon your ISF value and as such you may find you need to adjust your ISF and possibly your CR when you switch from Loop to Trio.

What to Expect After 7 Days

You've completed a week on Trio! Here's what you should see:

  • Dynamic ISF
    Dynamic ISF now has enough data. You now have the option to enable it.

    This is a great time to refresh Using Dynamic ISFand check your settings for Logarithmic Dynamic ISF or Sigmoid Dynamic ISF.

    Can't Enable Dynamic ISF?

    If Dynamic ISF does not give you the option to enable, you may have experienced one or more of the following:

    • You were not in closed loop for the full 7 days.
      • Trio needs 7 days of closed loop to safely enable Dynamic ISF
    • You had significant loss of connection with your CGM and/or pump.
      • Check your last week of Looping Statistics in the Stats tab in the Trio app. You need both 7 days and an 85% success rate to enable Dynamic ISF.
    • You enabled a significant number of manual Temp Basals with long run times.
      • When a manual Temp Basal is set, Trio is unable to complete a loop cycle for the duration of the temp basal. This will cause a reduction in your success rate. If you do not have 85% success rate for 7 days, you cannot enable Dynamic ISF.
