I have the apex jr and would like to add an eb8 to it. I already have 3 other modules hooked up (pm1, pm2, fmm) and display of course. Can i plug a eb8 into the base unit with the display and the 3 modules into the eb8? Or would that not work. I would like it to show as all one on the fusion app and them to work in unison if that makes sense. I know i can upgrade but i have everything i need besides a few extra outlets. Thanks!
