koboscout VS ntfy

Many years ago, I went a similar route and built a small T1D monitoring stack from scratch for myself. It even pretended to be a Dexcom Follow client so I could get CGM from Dexcom in near real-time. When Dexcom eventually changed their internal APIs and broke my data ingestion, I decided to finally give Nightscout a shot. I've never looked back since.

As I see it, the big advantage of Nightscout is that it is a de facto standard interface, with many integrations already existing. And it's easy to build add-on apps on top of its API. I've built about four myself [0], [1] and there is a big community of users and developers building other things such as [2], [3], [4]...

Even though Nightscout is a little bit messy and requires MongoDB, it's surprisingly easy to self-host. I'm using the stock docker-compose file from the main repo with only minor modifications. I run it on a $6/mo VPS. As an alternative, there are two or three hosted Nightscout services costing little more than that.

I highly recommend you to consider going this "standard" Nightscout route because it can save you work (and worries) in the future, and you get to connect with the community around it. In my experience, going all alone from the start was not worth it.

Slightly related, but I've also been working on and off for a few years on my own Type 1 Diabetes management solution (https://github.com/algao1/iv3).

I haven't had time to work on it recently, but it uses ntfy (https://ntfy.sh/) to send alerts and such.

I was thinking of eventually incorporating some kind of automatic remedial solution eventually to help keep my glucose in range, but haven't had any time to look into it yet.

If you go to the settings, there should be a notification category, which then contains another menu "App Notifications" where you can see all the apps that are allowed to receive notifications, but I don't know if this will stop google play services to receive these identifiers.

I use GrapheneOS, so I don't have any google play services running, but for the apps where I need notifications I use https://unifiedpush.org/ (only a few apps implement it) and I host my own https://ntfy.sh server.

Kind of similar, in the early days of COVID, I accidentally discovered that my state's website would have test results available several hours before they sent out the "view your results" email. So I made a script that would check the site every five or ten minutes and then ping me as soon as the result changed to something besides PENDING.

In the course of that I stumbled on https://ntfy.sh/ which solved the notification problem without needing Twitter, and I've used it since then to let me know when long-running scripts complete.

I connect any app that supports https://unifiedpush.org/ to a self hosted https://ntfy.sh instance for fully self hosted push notifications

changedetection.io just donated to the awesome crew over at ntfy.sh

For further monitoring & alerting about critical cpu temperatures (unlikely now) for example, I plan to use notify & something else. Haven't thought about this much yet though.

I've started tossing https://ntfy.sh/ alerts into my Deno apps to get push notifications for things I'm interested in

ntfy.sh

If it was for fun and to learn how, that's fair. But are you aware of https://ntfy.sh?
