Parity Switching Thermo
(Published on 22. June 2021, 01:00 by SudokuExplorer)
Each row, column and 3x3 box contains the digits 1 to 9.
Non-standard thermometer rules apply
Digits along a thermometer increase and alternate in parity (odd/even) from the bulb end.
For example, 1258 and 4789 are valid digits from the bulb end.
However, 12456 is not valid since 2 and 4 are both even.
You can try this on Penpa+, Sudokulab or F-Puzzles. Enjoy!
Solution code: Enter the 2nd and 8th rows

I must have broken the puzzle five or six times before I finally caught on to my mistaken assumption early on.

I'm sorry you had a tricky solve. In fact the two-cell thermo at the bottom isn't necessary for a unique solution, but I included it to make the solve path smoother (easier to find). Thanks for persevering, I hope you found a logical solve path in the end. :-)
