The device is designed i a way that, it should wake up every 30 seconds via RTC wake up timer or upon button press, read sensor values (for temperature and humidity ), if there is any change in these values , send packets via radio (SUBGhz) and enter STOP 2 mode.
This works for 3-4 days after which it does not wake up.
The radio core is held in reset before entering STOP 2 mode.
