Interesting. I have a whole house Generac too x 2. I don’t have a fancy set up like yours tho although mine came with the switching mechinism. Mine is the G0072910 model, and tho I am not one for putting wi-fi on any and everything willy nilly, but I would have to say it is handy. Also the wi-fi on the Traegeris very nice too. Out where I am is mostly farming and we are some of the last people to get power restored. Thankfully, this state has a real good track record for keeping the power on.
