I have several 3- and 4-way switches in my house that I want to enable with X10.
Sites like X10.com and Leviton suggest using an X10 controller for one end and then using special X10 companion switches for the other switches.
I spoke to someone at tech support at one of the X10 vendors and he confirmed my suspicion that you can use regular 3- or 4-way switches for everything but the controller at one end.
e.g., For 3-way:[X10 3-way master] [Standard 3-way]
For 4-way:[X10 3-way master] [Standard 4-way] [Standard 3-way]
The above makes sense electrically since only switch needs to be controlled remotely. Can anybody confirm that indeed one can use standard (and cheaper) 3/4 way switches for everything but the master?
