Marmitek X10 is standard X10.
I have in my house Marmitek X10, ACT X10, Some of our own X10 modules, Xanura X10 modules. And all work well together.
I also have a CM15 PRO. I think the BBS protocol is slightly different to X10 and uses RF signals. I don't think its compatible with the CM15.
You may want to ask the question on the BBS forum http://www.byebyestandby.com/forum/v...20df11c8d3e3d4
