Omnipod 5 support and a fix for 203 errors are now in the main branches of both Loop and Trio!
This work was only possible through the amazing work of our open-source community of developers supported by the Nightscout Foundation — a nonprofit focused on empowering development to improve the lives of those with Type 1 diabetes. As devices change and products come to their end of life, your support can help make effective systems for Type 1 diabetes available to everyone regardless of what devices they use.
Before you begin
While Omnipod 5 support has been thoroughly tested, it is still possible that something might not work when you first switch to the Omnipod 5 Pod type. Do not fill the Omnipod 5 Pod until you reach the “Pair O5 Pod” screen that tells you to fill it. When that happens, it means your installed code should work with Omnipod 5 Pods. Be sure to have a backup DASH or Eros Pod on hand in case the transition is not successful.
Key terms
OS-AID — open-source automated insulin delivery system. Trio and Loop are OS-AID apps for iPhones, while AndroidAPS is for Android phones.
Browser Build — a way to build and keep Loop or Trio updated using GitHub Actions in a web browser, without needing a Mac.
Omnipod 5 — the newest generation of Pods, after DASH. They have Bluetooth built in, so no link device is required with OS-AID. When used with the official Insulet system they can connect directly to a CGM, but with OS-AID your phone runs the app and must stay nearby.
Omnipod DASH — the generation of Pods after Eros. They have Bluetooth built in, so no link device is required with OS-AID.
Omnipod Eros — the older generation of Pods, before DASH. They use radio-frequency comms, so they require a link device (RileyLink, OrangeLink, etc.) with OS-AID.
