Thank you for being active on the forum!
If I understand correctly, what you want to do is to get a notification whenever the forecast for the coming night includes temperatures below 2 degrees. You want the notification to pop up somewhere in the evening before you go to sleep because you need to adjust the curtains and blinds manually. (Please correct me if I misunderstood your goal or the exact problem you’re facing.)
You can set it up using the options you already mentioned. You will have 2 “when” conditions:
- When > Time & day > Time is in between … > [insert your preferred time range for receiving the notification]
- When > Weather > Tomorrow’s weather > Temperature low > is below 2 degrees.
“Tomorrow’s weather” means the day after weather, so every day the trigg will check for the temperature tomorrow. It will evaluate temperatures during the entire day, not only during the night. However, most likely the lowest temperatures are during the night anyway so most of the time it should work the way you intend.
I hope this helped. Please let me know if you have any further questions!
