Secure the perimeter
This is the first ever puzzle that I tried to set. I think it's quite beginner friendly. Enjoy!
Rules:
1. Classic 6x6 sudoku rules apply: Place the digits 1-6 once in each collumn, row and 2x3 box.
2. Thermo: Digits on a thermo must increase from the bulb end.
3. Cages: Digits in a cage sum to the number on the top left corner of the cage. Digits within a cage may repeat if allowed by other rules.
Puzzle:
Lösungscode: Row 3, read left to right.

Thanks to everyone for their comments. Change was made so that the cages were not set as "killer", so as to not flag repeat digits as wrong. If this still doesn't work, please let me know.

Nice snack, but the rules need to be fixed in sudokupad indeed
Thank you for sharing !

Cute! If you use cages in which digits can repeat, set these as "cosmetic cages" in your setting tool. The conflict checker will then ignore them.
