Self-powered, wireless technology requires no batteries or additional wiring. EnOcean® technology converts the press of a switch or the slide of the key card into enough energy to transmit a wireless signal to power up or down receptacles, lights and thermostats. With 50 to 150 feet in the transmission range you can control unlimited receivers over the 315 MHz band without interference.
Switches can be placed anywhere within range of the receivers without running additional wires. This saves 1/3 the labor and materials of traditional installation by reducing the use of expensive copper wiring and conduit. During retrofit, there is no need to tear holes in walls to install a new switch.
