Hey Dave..
I have a bunch of their lamplinc and appliancelinc modules and have several
with the same problem.  They work fine until the power goes off, when the
power comes back on they are as if they were reset.  They lose their
programming and code setting..Very frustrating, some of them are behind
heavy furniture..I emailed Smarthome and they said "sounds like your getting
surges, we recommend a whole house protector"..Well..I have two..One in each
panel...
Now we have had several power failures and most of them last only 1-2
seconds..But seems the only thing not liking this is the smarthome
modules...

Anyone else having similar troubles?
John
