Temporary start my app in background?

Hello Knowers
I am trying to make an application that takes the data on soil temperature and humidity from NodeMCU.
So far it works satisfactorily.
I also have a notification (in the task bar) for "dry soil".
The application does not need to run continuously.
But when it doesn't work or is stopped by Android, I don't receive notifications!
Is there a way in a round of 6 hours for my app to start in the background, "do its job" in about 60 seconds and close again?

Excuse my English and Google translation!
I hope you understand me.
Thank you in advance.

You can try using the BackgroundTasks extension (should be on this Community; I'm on my phone, sorry).

The following extension would be another possibility... the question is, what happens, if the device is locked...

The BackgroundTasks extension was my first choice!
The Alarm Manager Extension was my second choice (because is not free :slight_smile:)
But and both are hard to uderstanding for me!
If can I to use some examples, that will be very big help for me.

If can to receive notification or start and then receive notification after the device is unlocked - it is OK.

can you share how you did it

You can find several example projects here App Inventor Extensions: Alarm Manager | Pura Vida Apps
