Global DLC1Harkon dead must be at 0; it is set to 1 at the end of "Kindred Judgement". So the attacks should cease if Harkon is killed.
However, blotting out the sun can cause attacks that ignore the time of day.
Habitation meaning any location with the keyword "LocTypeHabitation"; usually, any area populated by NPCs, including settlements and farms.
The change location event may be triggered by going in and out of buildings, but the attacks never occur more than once a day, unless you've the bad luck of having an attack cross midnight.

I killed harkon and never blot out the sun.
It seemed like a waste honestly to do. It's useful I'm sure it's just, tedious and you can get by without it. So I did it once or twice immediately after to watch the animation but never did it again.
Still attacked during the day, after Harkons death.
