push notification - esp32 with bmp280 pressure sensor via bluetooth

Good day, all :slight_smile:

I’m new here and really need your help.
I want to make a tire pressure monitoring application via Bluetooth using ESP32 and BMP280 pressure sensor (so far), with condition the application will show a push notification on smartphone if the pressure sensor number exceeds a certain limit.

I have created an application with 2 screens where the first screen is the login page which thankfully works well, and the second screen is the main display.

Thank you for your help :slight_smile:
*if the blocks is better changed, please let me know. i really appreciate any advice
