How Do WiFi Power Meters Work?
A WiFi power meter measures electrical parameters such as voltage, current, power, and energy consumption and sends the data through a WiFi network to an app, cloud platform, or energy management system. CT clamp models measure current without requiring the main conductor to pass directly through the meter, making them particularly suitable for retrofit energy monitoring. Depending on the model, WiFi power meters can monitor single-phase, split-phase, 3-phase, solar, or individual circuit loads.
WiFi Power Meter App and System Integration
WiFi power meter data can be accessed through mobile apps, cloud dashboards, or third-party energy management platforms, depending on the meter configuration. OWON models can support options such as Tuya, MQTT, HTTP, Modbus TCP, APIs, and integration with EMS/BMS or smart home platforms. This allows OEMs and system integrators to select between ready-to-use app monitoring and customized energy management solutions.

FAQs
1. What is a WiFi power meter?
A WiFi power meter is an energy monitoring device that measures electrical parameters such as voltage, current, power, and energy consumption and sends the data through a WiFi network to an app, cloud platform, or energy management system. Depending on the model, WiFi power meters can be used for single-phase, split-phase, 3-phase, solar, or circuit-level energy monitoring.
2. How does a WiFi power meter work?
A WiFi power meter measures electrical data directly or through CT clamps installed around power cables. The meter calculates real-time power and energy usage and transmits the data over WiFi for remote monitoring. CT-based models are especially useful for retrofit projects because they can monitor current without cutting the main power cable.
3. Can a WiFi power meter monitor 3-phase electricity?
Yes. OWON offers 3-phase WiFi power meters such as PC321, PC473, PC341, and PC4713 for different monitoring requirements. Options include clamp-based monitoring, DIN rail installation, multi-circuit measurement, and solutions designed for solar or energy management integration.
4. Can I monitor a WiFi power meter through an app?
Yes. Depending on the model and configuration, OWON WiFi power meters can support mobile app or platform-based energy monitoring for real-time data, historical energy usage, and remote access. Tuya-compatible models provide ready-to-use app monitoring, while other versions can support MQTT, HTTP, Modbus TCP, or APIs for customized platforms and OEM projects.
5. Can OWON WiFi power meters work with Home Assistant?
Home Assistant integration depends on the specific WiFi power meter model, firmware, and supported communication method. Models that provide suitable MQTT, API, or compatible third-party integration options can be used in Home Assistant-based energy monitoring projects. Integration requirements should be confirmed for the selected model before deployment.
6. Does OWON support OEM/ODM WiFi power meter projects?
Yes. As a WiFi energy meter manufacturer, OWON supports OEM/ODM projects for system integrators, distributors, smart energy solution providers, and other B2B customers. Available services can include hardware configuration, firmware customization, branding, packaging, cloud or API integration, and volume production according to project requirements.
