This one took me a long time! It wasn't clear to me from the outset that the digits were necessarily given digits (rather than just thermo lengths). It also took a long time for me to think to look at the thing that removes the majority of the ambiguity in the puzzle, so I spent a couple hours feeling like I was completely in the dark!

There was a typo in the solution code that I managed to test twice! Sorry.
