Zemismart Zigbee Energy Meters 3 Phases 4 Wire Power Meter

Zemismart Zigbee 3-Phase Energy Meter with 4-Wire Power Monitoring

The Zemismart Zigbee Smart Energy Meter is a compact 3‑phase, 4‑wire power monitor designed for homes with solar or advanced energy setups. It integrates with Tuya Zigbee hubs, Zigbee2MQTT, and Home Assistant to deliver precise energy data and actionable insights.

• 3-Phase, 4-Wire Energy Monitoring: Bi-directional measurement that captures household consumption and solar production across all three phases, with support for accumulated energy and time-based views (hourly, daily, monthly).
• Voltage Range and Compatibility: Supports standard mains like 208V and 415V, with a compact update-ready form factor suitable for modern electrical panels.
• Zigbee Connectivity: Works with Tuya Zigbee Hub and Zigbee2MQTT for Home Assistant control and automation; note that it cannot be directly paired with ZHA—use Zigbee2MQTT for HA integration.
• High-Precision Measurement: Energy accuracy within 1% tolerance, enabling reliable tracking of usage and solar export over time.
• Comprehensive Data Points: Measures Voltage, Current, Power, Power Factor, and Temperature in addition to accumulated energy totals.
• Robust Alarm System: Sends alarms for over/under voltage, high temperature, high power, high consumption, and an unbalanced-load condition to help prevent electrical issues.
• New Mini Size with Wide Voltage: Updated form factor that fits into standard electrical enclosures while covering a wide voltage range for diverse installations.
• Security and Safety: Built for safe monitoring in a live electrical environment, with alerting designed to prompt timely checks and maintenance.

The Zemismart Zigbee Smart Energy Meter empowers you to see exactly how energy flows in your home. With bi-directional measurement, it reveals both consumption and solar production, helping you optimize usage, maximize solar self-consumption, and trigger automations in Home Assistant via Zigbee2MQTT. The device's precise 1% energy accuracy supports better budgeting and planning, while the unbalanced-load alarm helps safeguard electrical panels from potential faults.

12 Quick Q&A for practical use

Q1: What is the Zemismart Zigbee Smart Energy Meter used for?

A: It’s a 3‑phase, 4‑wire power monitor that tracks voltage, current, power, energy, and temperature, with bi-directional capability to quantify both consumption and solar production. This makes it ideal for homes with solar and smart energy goals.

Q2: Which ecosystems does it work with?

A: It works with Tuya Zigbee Hub and Zigbee2MQTT for Home Assistant; this Zigbee version is not directly compatible with ZHA, so use Zigbee2MQTT to connect to Home Assistant for full data visibility.

Q3: What voltage ranges are supported?

A: It supports typical high-voltage mains such as 208V and 415V, with a compact, update-friendly design.

Q4: Can it monitor solar energy?

A: Yes. Its bi-directional measurement shows both household energy use and solar production, helping you quantify exports to the grid (useful for optimization in Home Assistant via Zigbee2MQTT).

Q5: How accurate is the energy measurement?

A: It delivers high-precision energy measurement within a 1% tolerance, which is reliable for monitoring trends and informing automation choices.

Q6: What data points does it report?

A: Voltage, Current, Power, Power Factor, Temperature, and Accumulated Energy (with hourly, daily, and monthly views).

Q7: What alarms are included?

A: Over/under voltage, high temperature, high power, high consumption, and an unbalanced-load alarm to help prevent safety issues in the electrical panel.

Q8: How often does it report data?

A: The Zigbee version reports data at a default interval of 600 seconds (10 minutes), providing a steady stream for dashboards and automations.

Q9: Is installation safe for a homeowner?

A: The device is designed for in‑panel mounting and live monitoring; professional installation by an electrician is recommended to ensure correct wiring and safety compliance.

Q10: How does it help with energy management?

A: By showing real-time and historical energy use, it enables targeted automations (e.g., solar export alerts, load shedding during peak times) in Home Assistant via Zigbee2MQTT.

Q11: How does it compare to single-phase meters?

A: A 3‑phase meter captures data across all phases, offering a complete view for multi‑wire systems and more accurate energy balancing than single‑phase solutions.

Q12: Who benefits most from this meter?

A: Homeowners with solar systems, energy-conscious households, and smart‑home enthusiasts who want precise, automated energy visibility through Home Assistant or Tuya Zigbee hubs.
