Well, good news / bad news...
Two of my X10 switches worked with the modified program - thanks Stu! But my X10 switch farthest away did not respond.
Is there a proper way to test different outlets... meaning, can I plug the PLM into an extension cord and try different outlets and if yes, what is the least involved - proper shut down / start up procedure?
Thanks guys. I was really starting to doubt my ISY purchase, but with a support community like this, I think I can make this work,
