What is the easiest way to tie multiple switches together. I have 3 sets of outdoor lights with each having a GE Zwave on/off switch.
What I want: if I turn on any of the outdoor lights have them all come on. If I turn off any of the 3 lights turn off the other 2.
I was thinking that this would be relatively simple to implement as a plug in. Do I need a plugin? If so which plugin should I look at to get started. Where is the best tutorial/documentation for plugins?
thanks
