Automatic sending of notifications when a specific temperature is reached

Configuration
1

I want to install an automatic device that will send a signal (Pushover) when the temperature is below -1°C. The automation must be active at a specific time (4:45 AM) and must send the notification three times.

However, in my case it was sent at a different time (2 AM).

Temperatures below -1°C were already reached earlier (around 10:30 PM).

Can anyone send me a guide on how to create it correctly?

The alert integration will send the notification multiple times:

Otherwise it’s hard to comment on why your automation isn’t working as expected without seeing it. Could you post the code?
