Zemi 3-Phase Energy Meter for Solar

Zemi 3-Phase Energy Meter for Solar: Bi-Directional Zigbee Power Monitor

The Zemismart 3-Phase Energy Meter delivers precise bi-directional energy tracking for homes with solar systems, enabling comprehensive solar energy monitoring of both household consumption and grid-tied production through a compact Zigbee device.

Accurate Real-Time Power Analysis

This 3-phase, 4-wire smart meter measures voltage, current, active power, power factor, and ambient temperature with 1% accuracy. Bi-directional capability distinguishes between grid import and solar export, ensuring accurate data for budgeting, load balancing, and optimizing self-consumption percentages.

Seamless Home Assistant and Zigbee Integration

Engineered for advanced automation, the device streams telemetry directly to a Tuya Zigbee Hub or via Zigbee2MQTT, serving as a robust Home Assistant energy monitor. Note that this unit requires standard Zigbee connectivity and is incompatible with ZHA; users can create automations to manage battery charging thresholds and high-draw appliance schedules based on live voltage, current, and power metrics.

Specifications and Intelligent Alarms

• Electrical Configuration: 3-Phase, 4-Wire
• Operating Voltage: 208–415V
• Measurement Precision: 1% accuracy class
• Monitored Parameters: Voltage, Current, Power, Power Factor, Temperature
• Customizable Alerts: Notifications for over-voltage, under-voltage, high temperature, exceeding power limits, and phase unbalance conditions

Solution for Solar Homeowners and Automation Builders

Designed for properties with multi-phase electrical infrastructure and DIY smart-home ecosystems, this Zemismart energy meter empowers proactive energy management. Users gain visibility into real-time power consumption trends, enable instant fault detection through configurable alarms, and leverage accurate measurements to maximize renewable utilization while preventing circuit overloads.
