I've confirmed that CFLs generate noise too -- when they are off there's
no problem but when you turn them on then there is some noise that
affects an INSTEON's switch ability to turn the light off. I have a
light fixture with three CFLs and I was getting unreliable comms with
the switch until I unplugged 2 or the 3 CFLs. Perhaps it is not all CFLs
and just the specific brand/model that I've got...

This part is something that I have never understood... it is stated
everywhere (Smarthome literature, common knowledge online, etc.) that
INSTEON has wonderful re-transmissions that make it more robust when
compared to X10. Sure, that's very nice. However, as far as I know these
re-transmissions are not part of the INSTEON protocol itself, i.e.
device firmware does not implement re-transmissions. Instead, it is the
INSTEON stack in the application the one that implements the
re-transmissions when an ACK to a command is not received. I know, the
end result is the same, but I think the marketing literature is a bit
misleading on this regard. Our INSTEON stack in MisterHouse does
implement the re-transmissions.
