Z-Wave is a next-generation wireless "ecosystem" that lets all your home electronics talk to each other, and to you, via remote control. It uses simple, reliable, low-power radio waves that easily travel through walls, floors, and cabinets. Z-Wave functionality can be added to almost any electronic device in your house, even devices that you wouldn't ordinarily think of as "intelligent," such as appliances, window shades, thermostats, and home lighting.
