I hope that you will find that this is a simple but fun puzzle. It is aptly named after the 1000-year-old wind-mills in Iran that are still in use today.
Normal Sudoku rules apply.
Cells of the same color contain the same digit.
Two cells that are separated by a white dot contain consecutive digits. If two cells are separated by a black dot, the digit in one of the cells is half of the digit in the neighbouring cell. Not all possible dots are given.
Thermometers in the grid contain digits that increase from the bulb end.

Thank you, alexd441!

Hi! Nice puzzle! One suggestion though: I've finished row 2 with 5 boxes still uncompleted, I would add another column, maybe, to the solution code.
