Get notifications from apps
I would like to make a LED strip blink whenever I receive a notification (at least for some apps) and do a different blinking color depending on the app (e.g. blue for Signal and green for WhatsApp) using a RP2040 hence I wonder if there is a way to receive these notifications in a quick way or not. Do I need to use the APIs? Can I link my phone to get the push notifications from them and maybe ID the app it comes from? It would be powered up by my computer via USB so maybe I can communicate with the RP2040 via USB to tell it which notification I get?
How to build notification system in Azure
I have a system running in Azure that accepts messages via a REST endpoint. The customer has a certain number of devices that send some data for example temperature and we present this data in a web interface. The part of the system that accepts messages is separate from the website (microservices!) but they access the same database (not so microservices?). I am building a new functionality that allows the customer to setup notifications. For example the customer defines that if any of his devices sends a temperature above 50°C then an e-mail should be sent. The notifications can be instant (or of relatively short period) or aggregated (daily, monthly, etc.).
Why are cloud services needed for push notifications?
We currently have a customer that wants us to implement push notifications to our app. The problem is that for this customer, security is really, really important…
I am not able to find any official documents, that state that the only way to send push a notification to an Android or iOS device via internet is the use of FCM / APNS.
Sadly, I don’t think that I can convince the decision makers to open ports to a Google / Apple service, if I can’t show them that this is a real necessity.
