Normal sudoku rules apply. Cells separated by a white dot are consecutive (not all possible dots are given). Digits on a thermometer must increase from the bulb end.

The grey line starts on the top left corner and ends in the middle cell. Along this line digits 1, 2 and 3 repeat in this order. There can be other numbers, before, after and between 1, 2 and 3 (also 1 doesn't need to be on the top left cell, and 3 doesn't need to be in the middle cell).

Apart from the given thermo, there are nine hidden thermos. All hidden thermos have their bulbs on a cell witht the digit 1 and they grow along the line. The tip of the hidden thermos is on the cell before the next cell with a 2, EXCEPT if 2 is immediately after 1, in this case the tip is before the next 3 OR if 2 and 3 are immediately after the 1, in this case the tip is before the next 1.

In this example you can see all the different possibilites for the tips of the hidden thermos
