Normal sudoku rules apply. There is a consecutive sequence moving clockwise in the corner boxes (1, 3, 7, 9), where digits connect by a single straight line. Once the sequence reaches 9, it goes back to 1. An example can be found here. Digits on a thermometer strictly increase from bulb to tip. Digits on an arrow sum to the digit in the circle. Xs and Vs sum to 10 and 5 respectively, not all X/V are given. Digits on a black kropki dot are in a 1:2 ratio, not all dots are given.
Solution code: Box 5 from left to right, top to bottom.

Very nice puzzle, I wonder if the instructions can be worded more clearly/completely though, and a solved example at least for the corner boxes might be more powerful than the partial example that's given
The bit that wasn't completely clear was that all the cells in the corner boxes are part of a single chain, leading back to the first cell in the end. Maybe saying something like "every cell in a corner box can see orthogonally the next higher digit in the next corner box around in a clockwise direction", I'm not sure if that's any clearer though
