Im gonna dive in here on this one ..
First of all .. we woudl have to know what type of fogger you have..
Second...as far as "hacking" there is really no way to do that... at least not that I know of..
Third .. once you knwo the type of fogger you have you MIGHT be able to get a regular remote WITH a timer ... SOME of them are universal .. some are not ..
Again it depends on the Fogger you have.. Me i have used timers , the type you buy with the foggers to begin with, and have had success using them on diffrent foggers.. it all depends.
More info would help to get better answers.
