A:Answer Yes; however, you must have a module on each switch location. I have them installed in 2-, 3-, and 4-way switch locations and they work great. The key is that you must connect all the circuits together so it's a "homerun" to each of the fixtures. This will mean all the fixtures are powered 100% of the time and the wall module is "talking" to the Hue lights directly to turn them On/Off.
While the circuit is powered 100% of the time, that doesn't mean full power is being drawn constantly. If the lights are turned "off" then its only the marginal standby current being used. We have several of these installed contolling numerous lights and our electric bill hasn't been affected enough to notice.
