What are the differences between the CM11A and the CM15A, other than USB? Just started to go back to X-10
in my new house, and hitting a lot of frustrations. I wanted to be able to use my Harmony remote to control lights in my family room. Needed a IR543(discontinued), found a dealer that still has at a high price. Bought the software and a bunch of new modules etc. Well the IR543 does not communicate back to run macros with the "CM15K", so it appears I need a CM15A, getting outbid on the ones I find on Flea Bay. Now I am wondering if the CM11A which appears reasonably priced is a suitable substitute until or if the CM15A becomes available again.
Also the light switches I ordered from X10 are re-certified and appliance modules are back ordered, after two months to get my order. It does not look good for this company IMHO.
