First attempt at creating a puzzle. Hopefully it's not a total disaster.
Rules
Normal sudoku rules apply
Digits on the thermometer increase from bulb to end
Each horizontal/vertical cage contains a two or three digit number (read from left/top to right/bottom), whose 9-digit binary representation corresponds to the parities of the cells in its row/column (0 is even, 1 is odd).
Example: A horizontal cage contains 91, which is 001011011 in binary. Its row must be even,even,odd,even,odd,odd,even,odd,odd.
Note that such a cage can only start at cell 5 or 8 as 91 consists of two consecutive odd digits.

Lovely puzzle! Well-set puzzle with interesting logic :-)
Those who find converting between binary and decimal a bit tedious might want to solve using this penpa link: https://tinyurl.com/y2hec9qw
It has powers of two around the border.

@sideG: Thanks for your feedback, glad you liked it. A slight tendency to enjoy tormenting yourself with mental arithmetic is certainly required for this mechanic.

Nice puzzle. A bit tedious with the conversion between binary and decimal, but luckily I enjoy that.
