Little devices like this are popular amongst some Diabetics for displaying their continuous glucometer data (I built something similar using an eink screen and the Dexcom home assistant integration). It's fun to see what people use these for!

My mom recently found out she has diabetes, and doing something like this for her I think would make life nicer. How did you manage to build something like this?

[–] joelectron@lemmy.world 4 points 2 months ago (2 children)

I can't really give you a step-by-step guide, but here's the gist of how I did it: I have a dexcom CGM, and use the dexcom share functionality in the app to sync the CGM data to a Home Assistant plug in. From there, the blood glucose data is treated like any other sensor value in Home Assistant, so the sky is the limit.

How you could implement this for your mom would depend on what brand of CGM she can get, and the level of tech aversion or savvy she is. xDrip and Nightscout are excellent projects which would also help you make something that uses or displays CGM data, if you didn't want to use Home Assistant.

Ahhh, honestly this was a lot more helpful than you probably know, so thank you very much for sharing <3.

How do I learn these talents!

Thanks for the insight. That's a really awesome use case: near real-time health tracker data.
