Has a doggy door but still pees in the house

Georgia girl here is almost 5 years old and has been peeing in the house daily since day 1. When we moved to our new house 2 years ago, we figured it would be alleviated because we have a fenced-in backyard and a doggy door out to it. While she uses the door constantly and the problem has improved, she still pees in the house every night (too lazy to go downstairs in the middle of her deep bass snooze, I think) and anytime of the day if it’s even slightly raining. She doesn’t poop though and she has a big brother (pitty mix) role model who NEVER goes in the house.

Crate training is kind of out of the question because 1.) I’m 95% sure she’d pee in that, resulting in both her and the crate needing a bath, and 2.) she would whine so loudly that none of the house would sleep. I’d also consider a doggy diaper, but I think she could get it off.

We are so fed up with daily steam cleans and lingering smells. Tips? Advice?
