Oh no! I spilled coffee all over my brand new Sudoku!
Part of it can be wiped away, the other part is too sticky and won't go away...
Well, anyway, maybe you can still solve it:
Normal Sudoku rules apply. Digits in cages sum to the number in the top left corner of the cage. Digits cannot repeat in cages.
There are two thermometers in this Sudoku: on a thermometer digits strictly increase from the bulb end.
The two main diagonals also contain the digits 1-9 exactly once.
This puzzle can only be solved on f-puzzles: https://f-puzzles.com/?id=yznpvfc6
Good luck!
Solution code: Row 2 followed by row 8 (18 digits, no spaces)

Added German description using Google translate, so I hope it is somewhat understandable (sorry for any mistakes)

Changed image to allow the puzzle to be solved without the f-puzzles link.
