Aeotec Home Energy Meter 8 – Energy meter, three‑phase, with 3 x 60A current transformers, Z‑Wave 800 (ZWA046C3A60)

The Aeotec Home Energy Meter 8 (ZWA046C3A60) is a Z-Wave 800 Series three-phase energy meter supplied with three 60 A current transformers.

The device measures the current of all three phases using current transformers installed in the electrical distribution board, while mains voltage is detected through its own power supply wires. Based on the measured data, it can provide instantaneous power, energy, voltage, current, reactive power, and power factor values, among others.

The three current transformers, each with a 60 A measurement range, are suitable for monitoring three-phase 230/400 V electrical systems with a neutral conductor. Measurement is performed without interrupting the circuit: the current transformers must be clamped around the phase conductors being measured. The device can handle consumed energy and energy exported back to the grid separately.

The Home Energy Meter 8 uses Z-Wave Plus V2 and Z-Wave 800 Series technology for data communication. It supports traditional Z-Wave mesh communication, Z-Wave Long Range, SmartStart inclusion, and S2 encryption. It can be used with Home Assistant, SmartThings, Homey, FIBARO, and other compatible Z-Wave hubs.

Key Product Features

• Z-Wave 800 Series and Long Range: The device uses Z-Wave 800 Series radio hardware and supports Z-Wave Long Range communication when paired with a compatible controller.
• Single-phase and three-phase energy measurement: The Home Energy Meter 8 product family is designed for measuring single-phase and three-phase electrical systems. This version includes three 60 A current transformers.
• Energy consumption and generation measurement: The device handles imported and exported energy separately, making it suitable for monitoring photovoltaic energy production.
• Per-phase measurement: Data from the three current transformers can be reported separately and as aggregated values to the control system.
• Measurement of multiple electrical parameters: Supported reports include active energy, instantaneous power, voltage, current, apparent energy, reactive power, reactive energy, and power factor.
• Non-invasive measurement: The split-core current transformers are installed around the phase conductors, so the full load current does not pass through the meter electronics.
• S2 encryption: Z-Wave communication can be protected using S2 security classes.
• SmartStart inclusion: With a compatible Z-Wave controller, the device can be pre-added to the network using its QR code or DSK identifier.
• Z-Wave repeater: Due to its continuous mains power supply, it can forward the traffic of other Z-Wave devices in a traditional Z-Wave mesh network.
