That's how I use mine. It runs fine for a half year or sometimes more,
then hangs up and does nothing. After a power cycling and battery
removal it wakes up again.

That is not encouraging. I'd have no problem improving a poor receiver
or transmitter design but when it comes to its particular micro
controller code I am not an expert. If losing that much time happens to
all of them and not just yours that is usually not a good sign for
firmware quality at all. Well, maybe switching to the CM15A isn't the
solution then.

I am still hoping that someday a better scheme than X10 comes to market.
But my hopes aren't high because home automation isn't advertised
enough. So it may not make it out of niche applications like yours or
mine any time soon.
