I have spent time surfing the web looking for compatible sketches/scripts that will allow the generation of alarm-based push notifications from a Uno Wifi Rev2 to a web client like Pushbullet. I also checked out RemoteMe.org but their stuff is for ESP32 and 8266.
If you know of any links that might work I would appreciate it.
Looking for ready projects is almost always a waist of time.
Split the project down into smaller pieces and look for similar projects. Modify the best example to fit Your needs.
Then integrate those parts to one piece.
Getting the alarm data is not the issue. That bit is finished.
Getting communications established with a push notification client is my roadblock.
There is plenty of push notification/SMS stuff on the web for the 8266 and esp32 but not the Uno WiFi Rev2 which uses different libraries.
I tried Pushbullet with a Youtube sourced script. To be honest I have tried so many different approaches that I forget the specific Pushbutton obstacle.
I am going to pursue your "curl" suggestion for sure; as soon as I understand what curl is. Lol.
Curl is a useful command line utility that lets you hit an endpoint and examine the results as text.
I usually start with curl to make sure that my authentication is right and to verify that what I got from the API was what I expected. Then I write the client code to do the same thing and parse the results.
