Zemismart Energy Meter 3Phase 120A (Tuya ZigBee)
The Zemismart Energy Meter 3Phase 120A (Tuya Zigbee) is a powerful and accurate energy monitor designed for three-phase electrical systems, using external Current Transformers (CTs) for easy installation and integrating with the Tuya Smart Life app via a required Zigbee hub.
Key Features:
- Connectivity: Operates on the Tuya Zigbee 3.0 protocol, which ensures stable, low-power communication. A Zigbee gateway/hub (e.g., from Zemismart or Tuya) is necessary to use the device.
- Measurement Capabilities: Provides detailed real-time and historical data for each of the three phases, including voltage, current, active power, accumulated energy (kWh), and power factor.
- Max Current: Designed for high loads with support for up to 120A per phase using the included split-core Current Transformers (CTs).
- Installation: Features a compact DIN rail mounting design and uses external CT clamps, allowing for installation without disconnecting the main high current wires.
- Accuracy: Delivers high-precision energy measurement with an accuracy class of ±1%.
- Bi-directional Measurement: The hardware can monitor both energy consumption from the grid and generation from alternative sources like solar panels. When integrated into platforms like Home Assistant via Zigbee, this data is often more accessible and clearer than in the standard Tuya Wi-Fi version.
- Alarms: Allows the user to configure notifications for abnormal power conditions such as over/under voltage or high current.
