Is it possible to assign a number of different modules to a single house code, unit code.The reason I ask is, for example, as soon as I assign A1 to Hall Light, the A1 house code is no longer available in the drop down menu when I am adding a second module. Also, my MS13 x10 movement sensor has the same address, A, as my hall light and I need to pair them both together. What I am finding is that even though my other MS13 movement sensors have different house codes and unit codes they are all activating the hall light.
