Normal sudoku rules apply. Digits on a slow thermometer must not decrease as they move away from the bulb. Digits may repeat when otherwise allowed. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. Thanks to @Zixyegh for a helpful suggestion which improved the puzzle. I think this puzzle is 1 star out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!

for jva:
you shouldn't be doing much goodliffing here.
standard procedure:
1) use cages to locate high/low cells. PAINT high cells with yellow or orange. paint low cells light grey.
2) step along the thermos, putting in the MINIMUM value ONLY. and in this puzzle, you transition to the big DIGITS immediately.
3) add a couple corner marks, and you are almost done

The thermos are the same color as the pencilmarks in the CtC app, makes them very hard to see
