RE: Using an LD11 as an appliance module ?

["Paul Gale" <groups2@xxxxxxxxxxxxxxxx>]

Marcus,

I can't answer your main question but I can say that I've had quite a few
occasions where I've had LD11's come on uncommanded. Not sure of the cause,
be it corrupt packets, interference or a neighbouring X10 system. I do have
an incoming mains filter though.

This is one of the reasons I'm finally going CBus - although that doesn't
help you I know!

Paul.
