Notification when temperature below 0 at night

[Donkey-Doug]

Please make ot possible to get a notification at a specified time (for example, 20:00) if in the upcoming night the temperature drops below zero.

Reason:
If this is the case, I will park my car inside such that I do not havr to scrape off the frost.

This is a neat suggestion, I'll keep it in mind for future versions. Thank you!
