The FIBARO Dimmer 2 is a universal dimming module with built in power metering. The device allows remote control over many different light sources, which will also extend the lifespan of the lightbulbs and reduce electricity use. The Dimmer 2 works as both a standard dimmer or as a switch within a two-wire or three-wire electrical system. The compact size of the device allows it to be installed in wall switch boxes or housings. FIBARO Double Switch 2 can be controlled either via Z-Wave network or with a wall switch through a direct connection.
