I really like the interactions between diagonal and “pointer” constraints, so wanted to make a thermo version. This is quite tricky but, resisting the urge to bifurcate, considering immediate consequences for the diagonals should (hopefully) produce a satisfying solve. If anyone enjoys this, they may wish to try some of the other recent puzzles using similar rulesets:

• Pointed Variants
• Boiling Point

Rules:

• Normal sudoku rules apply.
• Digits cannot repeat along the marked diagonals.
• Pointer Thermos: Digits along thermometers increase in value from the bulb end. Additionally, thermometer tips point towards a cell containing the digit within the bulb. The value in the tip indicates the distance to this cell. There may be other instances of the digit between the tip and this cell. If a thermometer has more than one tip, then each tip points towards a different instance of the bulb digit.
• Pointer Arrows: Digits along arrows sum to the value in the connected circle. Additionally, arrow tips point towards a cell containing the digit within the arrow's circle. The value in the arrow tip indicates the distance from the arrow tip to this cell. There may be other instances of the same digit between this cell and the arrow tip.

Below are two examples to illustrate the ruleset.
