Automating lighting
I am new to home automation so this will probably be a very simple question to answer.I have a screened in patio with four wall mounted lights spread out around the space. Each light has a separate switch.What I would like to be able to do is control and dim all four lights simultaneously from any of the four switch locations. Any ideas?

I would use an XPDF for dimming lights and you would use an XPT base and depending on your preferences, one of the faceplates to go with it. The XP2DX is an on/off and bright dim for one house code, which would mean each location would transmit either on/off or bright dim commands to the XPDF.
If the switches are currently run as a 3 way circuit (all switches are wired together to be used for the one light) you can simply use an XPD3 (master switch) and 3 XPSS (slave switches). Each will control the light and you also can use an X10 remote to control the lights.
