I have to preface by saying that this isn't really related to Home Assistant. I can't find a more generic home automation community on Lemmy and I figured someone here might have some experience with this so I hope is post is allowed.

I have a large masonry fireplace that I'm fixing some issues with. It has a fresh air intake that I'm venting outside the house. Code says the air intake also has to have a damper which can be closed to prevent the fire from burning out of control.

I'm planning to use a 24 volt power open/power close damper. I want to be able to modulate it with a wall control where it can be set in increments somewhere between 0% and 100% open. I'm sure I could engineer a creative solution but I wanted to see if anyone else had a simpler way of accomplishing this first.
