I’m sorry this is not advice, but what an abomination of a window that is.

instead maybe just tint with window with UV / heat resistant ceramic film

Window stickers are cute and fun!

Not sure on Z-Wave but you can get Lutron for angled windows. $$$$ though.

I’d go a different route and put window film there, maybe tinted or frosted glass

Stained glass stick ons?

A motorized shade is possible but very expensive and you would have to run wire because they take 35V and do not come as battery operated. They are also tension so the casette would be at the bottom and you would have cables running up to the top of the window.

Another solution would be fixed shades by Insolroll - but you wouldn’t be able to open and close it; would be fixed.

Personally i would go for the fixed shade option over tinting.

Tint that bitch and be done

I would tint it with 5% window film, or depending on the outside colour off the house, either silver or bronze reflective film

Assuming that is not the only window, you can tint it?

Not much of a view, so I would put up some stained glass, there are many who make custom shape. You can have a custom theme.

I just want to know who did the mudding and taping. They need to be fired.

Plywood

You could order film for the window to protect the heat coming in the house and reduce the brightness as well too. It’s similar to tint on your car.

maybe ikea blinds like these

it’s somewhat “adjustable” and can tilt when one corner hits the bottom first… largest is 48" though.

Or just mount it on the outside of the window/ceiling
