The 400,000 Subscriber Puzzle

Somewhat incredibly, Cracking The Cryptic looks to have reached 400,000 subscribers. Thank you so much to all of you who've joined us on this journey. Today's sudoku commemorates 400k and it's a quite beautiful puzzle by PjotrV. Give it a try at the following link:

Rules:
Normal sudoku rules apply. Cells separated by a white dot contain consecutive digits. Not all white dots are given. The grey line is a "Double Digit Thermometer" where it alternatives tens digits and units digits. Starting at the bulb the double digits increase along the thermometer. All double digits added together sum to 400. Digits along each purple line multiply to 400. [NB Some people have questioned whether r3c2 should be counted twice in doing the multiplication. It should NOT be. It only counts once.]

Sam Cappleman-Lynes has made an extremely clever 6x6x6 set of puzzles. We have released a solution video for this puzzle on Patreon and you can try to solve it yourself at these links (one to our software, one to penpa (which allows you to increase the size of the grids):
