About 20 years ago I had the brilliant idea of installing
X10-controlled floodlights under the eves of the house and
putting the X10 modules that control same up in what passes for
an attic.

Now something's getting flaky. There's this one set of lights
where I can hit "All On" on a controller and the lights come on,
but "All Off" will not turn them off - even though other lights
do get turned off.

We've been through a couple of other similar happening. In one
case, another controller would turn all lights on via "All On",
but no lights responded to "All Off".

The obvious is that the modules up there are at the end of their
lives and need tb replaced.

But I'm fishing for some other explanation before I crawl up
there and start ripping things out - and running Romex down the
soil stack to someplace more accessible to locate the new modules
in.

Controller "volume"? Some interaction with other devices on the
same circuit? Something with different circuits in the house
blocking some X10 commands?

Anybody have experience?
