Roman Thermo Somedoku

This is somedoku #12. Check out the rest of the puzzles in the somedoku series.

Rules:

Somedoku: Fill each cell with a digit from 1-9. Fill each row 'n' and column 'n' with exactly 'n' different digits, repeating digits as necessary.

Diagonal: Digits along the marked blue diagonal must not repeat.

Even: Cells with a grey square contain even digits.

Thermo: The digits along a grey thermometer must strictly increase from the bulb to the tip.

Roman Sum Lines: Red lines are divided into 2-cell segments. The sum of the digits in each segment must be one of 5 (V), 10 (X), or 15 (XV). A segment sum cannot repeat on the same line.

This puzzle uses a slightly modified version of the Roman Sum Lines constraint created by StartUp21. I made this puzzle for a Scojo setting prompt that asked us to build a puzzle in our signature style. I hope you enjoy it, if you do please leave a rating and a comment below!
