I have two light switches which control the same light (is this known as a 3way connection?). I would like to replace one of the switches with a Z-wave light switch so I can incorporate the light in some home automation scenes.
Can I do this by just replacing one of the existing light switches with a Z-wave enabled one? Do I need to look for a special 3-way Z-Wave light switch? Do such things exist?
I am handy, but definitely not an electrician.
Here is a picture of how the switch is currently wired:
