Sorry I confused you guys.
-One module I have has got two wheels; one wheel has letters (House Code) a,b,c,...The other wheel has got numbers; 1,2,3...
-The scond modules I have only have one wheel with (House code) letters; a,b,c...This one does not respond to the new wifi unit
-Do I understand correctly that the second modules I mentoned here will not work with the new wifi hub? If this is the case, this will be an easy fix. I will simply purchase more of the first modules and continue the new wifi shake down
