I have Type 1 Diabetes, and I’m always looking for fun/interesting ways to help me manage it, including some Home Assistant tools, like the Nightscout integration.

If your son is using an insulin pump, why are you taking a vial of insulin with you day-to-day? Even small pumps like the omnipod hold much more than one day’s worth.

When I do need to bring vials of insulin with me (if I’m camping in the summer for more than a few days, for instance), I just use a Frio pouch. They’re little evaporative coolers that keep the insulin cold enough. I’m sorry for ignoring your question, but it sounds like you could be making things more difficult for yourself than you have to.

I’m rocking in a hammock in my backyard, while the portal solar panel I got for camping charges my bike battery. The sun is definitely the most useful thing right now, giving me next week’s commute!
