Fix Home-Assistant statistics and energy erroneous values

Following are some notes about ST application notes I read to design an STM32L151 board.
I finaly published them: sources of my wireless sensors are available here.
I wanted to try if a 100% DIY process to reflow a small batch of boards. For about 10 boards it is cheaper to hand solder them than ordering a stencil, but I was wondering if it can be faster to manually cut a stencil and reflow the boards on a frying pan.
As I did not found any help over the Internet on that subject but read that other people have this problem I publish here why the buttons of my cruise control were not working.
I started one year ago when suddenly all the buttons were swapped:
Minus was not working anymore Plus was acting as minus Pause was acting as plus As I was able to use it I did not do anything, considered that it was behind the airbag.
