Counting Thermometers

Play in Sudokupad
Previously I published a counting circles puzzle where the bulbs of the thermometers were also counting circles. Lately I solved some puzzles with counting killer cages which I really liked. This puzzle uses all of the thermometer cells as counting cells.
Normal sudoku rules apply.
Digits on a thermometer increase from the bulb to the tips.
A digit N that appears on any thermometer cell must appear N times on thermometer cells. (Counting Thermometers)
Solution code: Row 7

I got to the end and started guessing. But then remembered that they are counting cells so went back and solved it properly.

Very fun ruleset and a nice smooth solve path.
I'd love to see a more challenging take on the same rules after this :)
--thank you! The difficult part is making the puzzle have only one solution. Without careful organization there are just not enough low number clues. Believe it or not, this was the hard version of the puzzle.

Such a fun rule set! Never too challenging, but with enough friction for a lovely solve!

Absolutely wonderful puzzle. Never tried a counting thermo before, so quiet difficult for me to break into. But a blast to understand more og more of the principles of counting thermo when breaking into the puzzle.

Very smooth and clever counting puzzle. Difficulty depends on experience on counting puzzles. To me rather 1* from the solve time but a brilliant one thx.
