The Fibaro Z-Wave Single Switch 2 is a wireless Z-Wave module which can control appliances or lighting up to a maximum load of 2.0kW. 

• Control the ON-OFF function of a circuit remotely or using a wall switch
• Compatible with all Z-Wave networks
• Acts as a repeater expanding your Z-Wave network
• Wide range of compatibility with existing light fittings and does NOT require expensive cabling
• Control loads up to 2.0kW (8A)

• Advanced microprocessor control
•  Active power and energy metering functionality
• Works with various types of switches – momentary, toggle three-way, etc

The Fibaro Z-Wave Single Switch 2 is a smart Z-Wave module capable of remotely operating your existing light fittings. It works with Z-Wave enabled controllers (AUS/NZ version) and can be controlled individually or as part of a group in a pre-configured Scene.

The device is designed to operate inside your wall socket and can be easily installed by a qualified electrician.

This Fibaro Z-Wave Single Switch 2 requires 3-wire (including neutral) installation and works with an AC (110-230V) or DC (24-60V) power supply. 
 

Power and energy consumption.

The Switch 2 allows for the active power and energy consumption monitoring. Data is sent to the main Z-Wave controller, e.g. Home Center, Homeseer, Vera etc..

Measuring is carried out by the most advanced micro-controller technology, assuring maximum accuracy and precision (+/- 1% for loads greater than 5W).

Electric active power – power that energy receiver is changing into a work or a heat. The unit of active power is Watt [W].

Electric energy – energy consumed by a device through a time period. Consumers of electricity in households are billed by suppliers on the basis of active power used in given unit of time. Most commonly measured in kilowatt-hour [kWh]. One kilowatt-hour is equal to one kilowatt of power consumed over period of one hour, 1kWh = 1000Wh.

The Switch 2 require the power consumption of connected load equal to 5W or greater to correctly measure the power and energy.

Power measurement can contain mains voltage fluctuations within +/- 10%.

The Switch 2 stores periodically (every hour) the consumption data in the device memory. Disconnecting the module from the power supply will not erase stored energy consumption data.
