The Wireless Energy Meter (WEM) is a smart device that performs quasi real-time measurements of the electricity consumption of the home by continuously monitoring the power line.
WEM will be installed into the main distribution board, with the amperometric clamp closed around the live wire of a 1-phase system. This allows WEM to measure the line voltage and current, and thus compute the total power and energy consumption of the home.
After a simple configuration phase, WEM starts reporting the measurement it takes to a central controller device, such as a home gateway, by means of the Z-Wave wireless technology. Z-Wave is a widespread and interoperable wireless home control technology based on the ITU-T 9959 open standard.
WEM has an intuitive user interface, with a LED informing the user about its current state, and a push button to let the user issue the necessary commands.
WEM can measure and report the following physical dimensions: Total Accumulated Active Energy (Wh), Instantaneous Active Power (W), RMS Voltage (V), RMS Current (A).
WEM allows to fine-tune the way the measurements are performed and reported by means of several parameters, which can be set by most controllers on the market.
