A Tuya WiFi smart power meter combines real-time electricity measurement with WiFi connectivity, app-based monitoring, historical energy data, and supported smart automation. Depending on the model, CT clamp sensors can be used for non-intrusive monitoring across single-phase, split-phase, or three-phase electrical systems.
Also commonly described as a Tuya WiFi energy meter, this type of device can be used for home energy monitoring, commercial buildings, solar installations, and smart energy projects.
For system integrators, distributors, and energy solution providers, choosing the right meter depends on the electrical system, CT range, installation method, monitoring requirements, and integration platform.
What Is a Tuya WiFi Energy Meter?
A Tuya WiFi energy meter is a connected device that measures electrical parameters such as voltage, current, power, power factor, and energy consumption and sends the data through WiFi for remote monitoring.
Compatible meters can connect with Tuya Smart or Smart Life for app-based monitoring, historical energy data, and supported automation. Depending on the design, Tuya energy meters are available for single-phase, split-phase, three-phase, CT clamp, DIN rail, and multi-circuit applications.
Key Features of a Tuya WiFi Smart Power Meter
Modern Tuya-compatible energy meters can provide more than basic kWh measurement.
Real-Time Energy Monitoring
Monitor voltage, current, power, power factor, frequency, and energy consumption, depending on the meter model.
Historical Energy Data
Review electricity usage over time to better understand consumption patterns and support energy analysis.
Tuya Smart / Smart Life App
Access real-time and historical energy information remotely through a compatible mobile app.
Smart Automation
Use supported energy values to create automation with other Tuya-compatible devices.
Solar Energy Monitoring
Models with bidirectional measurement can monitor both electricity consumption and solar energy production.
Tuya WiFi Energy Meter with CT Clamps
CT clamp-based Tuya WiFi energy meters measure current using external current transformers installed around electrical conductors. This makes them useful for retrofit installations, residential panels, commercial energy monitoring, and solar PV projects.
CT range should be selected according to the expected electrical load. For example, an 80A Tuya WiFi energy meter may be suitable for lower-current applications, while larger loads may require higher CT ratings.
Buyers should therefore consider CT range, number of monitored circuits, electrical system, and installation environment rather than choosing a meter based only on WiFi or app compatibility.
Tuya 3-Phase Energy Meter
A Tuya 3-phase energy meter provides connected energy monitoring for three-phase electrical systems. It can be used in commercial buildings, workshops, solar installations, and other projects where three-phase loads require centralized energy visibility.
When selecting a three-phase meter, check the supported wiring system, number and range of CTs, bidirectional measurement, installation method, and communication requirements.
Tuya Energy Meter and Home Assistant
Home Assistant compatibility depends on the specific meter and integration method. Selected OWON Tuya energy meters support Home Assistant integration, allowing energy information to be incorporated into a broader smart home or energy monitoring dashboard.
For example, the PC4713 Tuya version supports Tuya automation and HA platform integration. It also provides WiFi and Ethernet connectivity, bidirectional measurement, and historical energy data.
Typical Applications
Tuya WiFi smart power meters can be used for:
• Home and whole-building energy monitoring
• Commercial electrical panels
• Solar PV monitoring
• HVAC and major electrical loads
• Multi-circuit energy monitoring
• Electrical retrofit projects
• Smart building and energy management systems
The appropriate meter configuration depends on whether the project requires single-phase, split-phase, three-phase, whole-system, or individual circuit monitoring.

How to Choose a Tuya WiFi Smart Power Meter
Before selecting a meter, consider four key factors:
Electrical System: Determine whether the project uses single-phase, split-phase, or three-phase power.
CT Configuration: Select the appropriate number and current range of CT clamps according to the monitored loads.
Monitoring Requirements: Determine whether you need whole-system, individual load, multi-circuit, or bidirectional solar monitoring.
Integration: Confirm Tuya/Smart Life compatibility and any additional platform integration requirements.
For B2B projects, OEM/ODM requirements such as branding, firmware, CT configuration, and system integration may also need to be considered.
