You can find my other Entropy sudokus here:
Entropy Sudoku
Entropy Killer
Heated Entropy
Rules:
Sudoku: Fill every row, column and 3x3 box with the digits 1-9.
Thermometer: Digits along a thermometer have to strictly increase from the bulb to the tip.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Have fun solving!
Solution code: Row 2 followed by column 2 (18 digits)

Contained a few very nice logic steps that were hard to spot, but very rewarding to find!
Thanks!

Tricky, but not too hard, unlike some other ones that i am still grappling with :-) Thanks for this exciting new variant, @ Mad_Tyas :)

Brilliant puzzle. The simultaneous simplicity and complexity of entropy continues to astound me

It's not that hard, but it took me a very long time. Very enjoyable though!
Thank you for the puzzle!!!

It took me awhile to pick up the entropy constraint so it was a bit of a struggle, but very beautiful throughout. Thanks! I look forward to trying the others.
