You should definitely try using the build in logic AND cards, and look at the current luminescence level with that, and have the time as trigger (8:00), instead of the luminescence becoming bigger then 35.
Of course you can also ad more condition cards like It is after Dawn (30) if it makes sense, what I cannot judge in your case.
Regarding the DayLight - Yes/No variable. Such variables make sense if you can use them in many flows. But only for this particular flow, it makes no sense. You need additional flows and an additional variable.
But this is only my personal opinion.
Seems I didn’t explain it well enough.
– Logic card X is not greater than y: How should this card work if it’s not triggered? The connecting lines from the trigger cards to the logic card are missing.
– The value of the logic card X is not greater than y: In my screenshot I explicitly pointed out that not the value 50 but 0.5 has to be entered.
