My system is not what I consider,
extensive. I went to the Pro to expand it.
Configured in my CM11A is 6 Dimmable modules
(Plug and Wall), 14 Appliance modules(5
have duplicate house/unit codes), 2 20
amp/220vac modules, 4 Motion sensors, 29
macros all on 5 different house codes. I
have different groupings for different
functions because I like to use the all
units off per house code. I mask out my
motion sensors during the day by feeding
the transceiver module through an appliance
module, and switching the appliance module
on & off via my timed macros. With all
this, I’ve never gotten as far as my one
main timer to turn the lights on at dusk +
10… That’s where it always fails. I have
thought maybe I have some bad memory and so
added dummy modules to this main macro,
shifting my main macro into other memory
locations. The CM15A simply cannot handle
my main timed macro to start my evening
lighting events let alone, the rest of my
stuff. FYI, in this main macro is the ON
command to command the masking appliance
module for my exterior motion sensors so
I’m not getting communication on my lines
during the daylight hours. I have used an
oscilloscope on my AC lines measuring it
against the wave forms I have found on
other sites, to ensure I don’t see anything
else that should not be there. The CM11A
works 99.99% of the time and I’ve had that
for 5 years… The CM15A always fails
miserably! I too have communicated my
findings to X-10, but their lack of
response has conditioned me to stop that
avenue.
