Z-Wave Plus flush-mounted, 1-way Switch from wiDom - WPM1.04S with Electric Parameters Metering feature.

The smallest device in its category worldwide, and the only device specifically intended for use both as a Relay Switch with integrated Power Meter, and as an Energy Meter either at the point of entry of your electrical system, or on a section of the latter. Device featuring an internal shunt resistor. In addition to Power measurements, the device also provides data for Energy, Voltage, Current and Power factor.
The only device capable of implementing an active energy-saving management policy defined by the user according to his energy consumption, or to the amount of energy produced by his solar power system. It automatically connects and disconnects a specific load if the threshold limit is exceeded, or “supplies” the required power, momentarily excluding non-priority loads.
