X10 Pro: Yes, the LED was staying on after
I stopped pressing a button on the remote.
As for if it is new behavior for my IR543,
it only arrived on Wednesday so it has
always been like this (I guess). ;-)
I did some more experimenting tonight.
When I got home from work, it worked just
fine, but after watching TV for a while (I
guess about an hour) the problem returned.
When I moved the IR543 further from my TV,
it starting working again and when I moved
it back, it immediately stopped working
properly. I tried creating a Faraday cage
by wrapping it in aluminum foil (obviously
leaving the front open and it completely
stopped working while it was wrapped.
After I turned the TV off for about an hour
it started working normally again (with the
TV on), so it seems to only be a problem
when the TV is warm.
One other thing I did notice is that the
LED will eventually turn off on its own
(after 5 or 10 seconds). If you wait for
the LED to turn off before pressing the
next button, you can successfully send a
command (ex 5–wait–ON will turn on lamp 5
and 5–wait–6–wait–ON will turn on both
lamps 5 and 6).
Due to lack of shelf space up until now I
have had it standing on its side. I have
now moved it onto a shelf where it can sit
flat and I will see if that fixes the
problem.
