This is no ordinary wall switch. Insteon Wall Switches like the Insteon 2432-292 can be remotely controlled from almost any device in your home: Sensors monitoring doors, windows, leaks and more, remotes, keypads and other wall switches throughout your home, even your smartphone when used with the Insteon Hub. With Insteon, every wall switch can control every other wall switch, no extra wires needed. Just a few taps of the set button and you've made a 3-way switch. Want to add another? Make it a 4-way - or 5-way. There's no limit to Insteon's multiway switching. No wall switch is more customizable.
