X10 Y2K failure

[Raymond <Reb.barnett@xxxxxxx>]

Just a quick warning to anyone who might be nearly as dim as I am!

I know the CM12U's lack of Y2K compliance has already been posted to the
group, but I'd ignored the warning on the basis that my CM12U isn't
currently programmed to do anything useful. It was however still plugged
in, and it's failure has strange symptoms which might not be obvious to
you... It appears that it isn't just a case of macros firing
incorrectly, but in my case the CM12U can lock up and jam the mains with
spurious X10.

Since we came back of holiday, at around 11pm each night the lights did
an all-units-off, which was a bit spooky. As it happens I'd been
tinkering with Comfort so this initially got the blame. I proved it
wasn't. It then occured to me that our new neighbour has kitted his
house out with timer modules, so maybe he was playing with X10 modules -
he wasn't. I happened to have the cover off of Comfort, and noticed that
after the failure, the 7223 X10 transceiver was blinking it's LED to
indicate repeated transmissions. Out came all X10 modules, with the
CM12U being last to take the blame - the blinking stopped.

Hope this helps someone.

Ray.
