Its okay, I understand you’re reaction this isn’t a easy project with the lack of knowledge I have. So thanks again for the effort!You will have to find an appropriate module, although I don't know from the documentation of your valve if the 5V signal would work. It's easy to get 5V from 12, but all these details, which honestly are simple, compound to make a project that needs either knowledge or handholding.
Some people here will take something like this on, and help with all the details, but it's going to be a step-by-step process.
I have too many things going on to be helpful with yet another project so I am trying to avoid leading you in a direction you can't go by yourself.
