Smart Electricity Meter Wi-Fi Tuya Single-Phase 80A DIN Rail Energy Monitor

Imagine a homeowner who wants to track the energy consumption of a specific circuit in the garage, or a small business owner monitoring the power usage of a refrigeration unit. The Smart Electricity Meter Wi-Fi Tuya is a single-phase DIN rail energy meter that provides real-time monitoring and remote control via the Tuya Smart or Smart Life app. With its 80A maximum current rating and Class 1 accuracy, it delivers reliable measurements of voltage, current, power, energy, frequency, and power factor. The built-in Wi-Fi connectivity (2.4GHz) allows seamless integration with Amazon Alexa and Google Home for voice commands, while the backlit LCD display offers clear on-site readings. Installation is straightforward on a standard 35mm DIN rail, and the compact 1P module width saves space in distribution boards. The meter also features configurable overload protection and remote on/off switching, making it a versatile tool for energy management and automation.

Why choose it

This meter stands out for its combination of high current capacity, precise measurement, and smart home integration. Unlike basic energy monitors, it offers remote control and overload protection, enabling you to not only track but also manage your electrical loads. The Tuya ecosystem ensures broad compatibility with other smart devices, and the DIN rail design makes it a professional-grade solution for both residential and commercial installations. Its wide operating temperature range and flame-retardant housing ensure durability in various environments.

Ideal use cases

• Monitoring energy consumption of individual circuits in homes or apartments
• Tracking power usage of specific appliances like EV chargers, heat pumps, or workshops
• Integrating into smart home automation for energy-saving routines
• Remote switching of non-critical loads to avoid peak tariffs
• Sub-metering in rental properties or commercial spaces for billing purposes

Good to know

The meter requires a neutral connection and is designed for single-phase systems only. It does not include a built-in battery; historical data is stored in the cloud via the app. For accurate readings, ensure the current transformers (if used) are properly sized. The device consumes less than 1W of power itself, minimizing its impact on measurements. Voice control requires a compatible Tuya hub or direct Wi-Fi connection to the app.
