Good day, all 
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
*if the blocks is better changed, please let me know. i really appreciate any advice
