What’s happening?
Omnipod 5 pods work out-of-the-box with the latest versions of 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.
What's Loop? What's Trio?
Loop and Trio are both open-source automated insulin delivery (OSAID) systems for patients with Type 1 diabetes, built by the #WeAreNotWaiting community. They are apps which you build and run on an iPhone that connect with compatible insulin pumps and continuous glucose monitors. Both apps are maintained by a shared community of developers and are not formally approved by any regulatory body.
Frequently asked questions
Can I switch to using Omnipod 5 pods now?
Yes! Omnipod 5 support, along with a fix for 203 errors, is now in the main branches of both Loop and Trio. Update your app to the latest version, then switch your pod type to Omnipod 5.
See the Omnipod 5 compatibility page for known limitations, setup instructions, and more detailed FAQs.
How does this affect Android users or AndroidAPS?
Loop and Trio are for iOS (iPhone) only. If you are very keen to use Omnipod 5 pods, you can get an iPhone and switch to Loop or Trio.
While we don't have anything to announce today, there is work being done on supporting Omnipod 5 in AndroidAPS - it is just not ready and doesn't currently have an ETA.
You can keep up to date on development progress by monitoring the AAPS Users Facebook group or the WeAreNotWaiting Discord server.
Does the iPhone 16 or 17e still have connection issues with Omnipod 5 pods?
There has been no indication that the iPhone 16 or 17e have the same connection issues with Omnipod 5 pods as with DASH Atlas pods.
Does the Omnipod 5 have the 203 errors?
We can’t guarantee you won’t encounter a 203 error or any other error, but at this time there has been no indication that the frequency of 203 errors persists with Omnipod 5 pods.
What does this mean about support for other pumps, like Mobi?
The same developers working on Omnipod 5 are also working on Mobi. Omnipod 5 took priority due to the drastic increase in 203 errors and iPhone 16/17e communication issues. We are still working on Mobi and hope to have an update for you… soon™️…
How did support for Omnipod 5 happen? What can I do to help?
Loop and Trio are projects built and maintained entirely by volunteers, and they will always be free to use. The Omnipod 5 driver alone in OmnipodKit represents years of volunteer work by open-source developers, supported through the Nightscout Foundation. If these systems have helped you and you’d like to help support the community, the Nightscout Foundation is a nonprofit focused on empowering development to improve the lives of those with Type 1 diabetes and would be grateful for your support.
