Oh thanks Dave.
I'm an older x10 user but am looking for a wired solution. i have to mount the sensors high so i don't want to revisit them.
thanks for the link to the 'robot security' light. i definitely want a 'spooky' look or action to curtail use of the pathway.
i also had something like this in mind...when you start at one end of the path, the light on the opposite end comes on.
again thanks for the ideas.
