** Rules Revised **
Solution has changed since original version
Rules
Normal sudoku rules apply.
The corner cells in each boxes are highlighted. The digits 1 to 9 appear 4 times each in highlighted cells (not necessarily in different corners).
Arrows outside the grid designate the sum of digits along the indicated diagonal, but only one of these sums is given. The total sum of all these sums (including the given sum) is 178.
Digits on a thermometer increase from the bulb end. The sum of the bulb digits is 18.
In cages, digits sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage.

Notes
I think the break-in to this puzzle is pretty difficult.
This is my first puzzle I'm publishing, so let me know in the comments if there are any issues
Solution code: 18 digit code of column 9 (top to bottom) and box 7 (left to right, then down)

Clarified rule about corners

The rules intention was not full disjoint groups, but disjoint groups for the 4 corners. So the top-left corners of all the boxes contain the digits 1 to 9, as do the top-right corners, the bottom-left corners, and the bottom-right corners.
Thanks for giving it a try! I'll try to take a look at yours.

By 'Each digit appears in each corner of a box exactly once.', did you mean in every position in a box, a.k.a. Disjoint Groups, or only the 4 literal corners of a box? I initially took it to mean the latter, but when I couldn't solve it that way I solved it asuming you did mean every position, so if that is what you meant and I didn't just get lucky, you should probably clarify that rule a bit.
Other than that, this is a very nice puzzle! I recently started setting puzzles as well. Currently working on my second sudoku. Maybe you would like to have a look at my first sudoku, if you have time?
