Moved from CP290 (!) to CM15A - What a disappointment!!

I could have sworn I read somewhere that the CP290 used to really put some signal on the lines, and that the later controllers don't have the oooomph.

That's about the extent of my EE vocabulary: ooooomph.

That is a highly technical term which should not be bandied about willy nilly. Use it with caution.

Plus the Windows version of Smart10 still only works with the CP290, its the X10 version of putting a Maserati engine in a Ford Model T.  The CP290 is 1980's   There's ZERO support anywhere for it.
