I have a three-way switch setup where I’d like to replace one or two of the existing switches with a Z-wave zone controller. Can this be done? Can anyone help with wiring instructions for my electrician? I don’t want to purchase the items until I know for sure that it can be done. Thanks. ps: I have the same question for a few two-way switch setups I have, where I want to replace one of the two-ways with a zone controller
