Awesome puzzle! Here's an alternate solver if anyone prefers it.

Sorry for the long story, but, speaking as a beginner to sudoku, I felt like I've gone on a journey of awakening with this puzzle!
My first solve was 2.5 hours long, and I felt like a total idiot, especially when I accidentally lost the solution code.
My second solve was roughly 2 hours long, and some of the logic with the non-standard regions started to click, but I still felt like I was bending over backwards to find some of the numbers. And I lost the solution code again!
Finally, during my third solve, which took an hour and 15 minutes, the thermo logic finally started to click, and I was able to see that this puzzle was never meant to be so mind-bendingly hard in the first place! I feel like I now have a better idea of what to look for when solving other similar puzzles now. Thanks!

I had to colour a bit to see some fun logic a third of the way into the puzzle.
It wasn't necessary, I was just being an idiot. Very nice puzzle, and apart from that I managed to keep a very satisfying pace.

I came back to this after an evening or so. I ended up solving most of the outside ring and the entire cross, and had a lot of nonsense in the middle boxes. I deleted my pencil markings and started redocumenting. Hit a lightbulb moment and finished rather fast. Thanks for this!

Looked pretty easy but got stuck pretty fast. Then after one hour of very slow progress i got completly stuck for another hour. Then i started coloring a 23 pair around the grid which led me to the solution. Liked the last part very much!

Not nearly as easy as it looks.

Loved the hidden logic in this one! Glad to find a great puzzle after a sudoku hiatus! :)
