smtp4dev VS ntfy

smtp4dev https://github.com/rnwood/smtp4dev - works well in docker, has api, can selectively forward to a real smtp

depends on the infrastructre setup, but if you're able to specify smtp server the backend will use you can you something like https://github.com/mailhog/MailHog or https://github.com/rnwood/smtp4dev to catch any sent email, regardless of email address and read it via the respective api. Both mailhog and smtp4dev have decent api documentation.

If so you could check out smtp4dev, it gives you a locally hosted client that you can use to intercept any mail send out by your app and displays them in a nice web based gui interface so can see what they look like.

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?
