The Profiles screen under Remote can switch, create, edit, rename and delete profiles, and edit the scheduled starts, for Loop and Trio. It only shows these when the app lists the commands. Before sending, the review shows a diff and warns when a change gives more insulin, and a change to the active profile says that it changes dosing at once. When the reply push is lost, LoopFollow reports the command as applied once the uploaded profiles show the change. Loop with the Profile Save & Load customization keeps switch only. Loop push bodies are serialized without escaped slashes, so the size check measures what is sent. Glucose values in mmol/L are shown with one decimal.

Companion to LoopKit/LoopWorkspace#583 and nightscout/Trio#1766.

Testing so far, for reviewers.

On real phones. LoopFollow ran on an iPhone SE against Loop and Trio on an iPhone XS Max, over real APNs, against test Nightscout sites. Both apps ran with an Omnipod DASH pod filled with water, lying on the table and not on a body.

• Against both Loop and Trio:
  • switch, create, edit of the active profile, rename and delete;
  • deleting the active profile or Default is not offered, and the phone refuses it as well;
  • the scheduled-start editor (add, pause, resume, delete);
  • a conflict after a change on the phone, and a missing profile.
• The review before sending: the diff, the more-insulin warning, and the warning that a change to the active profile changes dosing at once.
• When the reply push is lost, the command is reported as applied once the uploaded profiles show the change. This happened in practice with both apps, and was also forced.
• Loop with the Profile Save & Load customization: the Profiles button works for switching only, and create, edit, delete and scheduled starts are not offered. After Loop is upgraded to the profiles version, the full set appears.
• Loop without the customization: the Profiles button is greyed out and explains why.
• Switching the glucose unit in Loop and in Trio:
  • previews follow the uploaded profile document;
  • mmol/L values are shown with one decimal;
  • an edit made from a preview loaded before the switch is applied correctly or refused, never applied wrongly;
  • values the caregiver didn't change stay exactly as stored on the phone, in both Loop and Trio.

In the simulator. The full unit test suite, plus end-to-end runs against a mock Nightscout with Loop and Trio.

In daily use: I'm running this in vivo, with LoopFollow on an iPhone 16 Pro Max following Trio on an iPhone 17 with a Medtrum Nano.
