This WiFi Smart Energy Meter is a compact and integrated device designed for residential and light commercial electrical monitoring and protection. It combines multiple functions into a single unit: a 63A capacity relay switch, a circuit breaker, an earth leakage protector, and an over-under voltage protection mechanism. The meter measures active energy consumption in kWh and provides real-time power usage data via a wireless connection. It operates within an input voltage range of 80-300V AC, making it suitable for various global electrical standards, including 110V systems. The hardware is built with flame-retardant materials and a durable ABS外壳, ensuring reliable long-term operation in panel boxes or distribution boards.

The internal components are precisely assembled to maintain consistent switching performance and accurate energy readings. The device connects to a 2.4GHz WiFi network and pairs with the Smart Life app, allowing users to monitor energy consumption, set voltage thresholds, and control the relay remotely. It supports voice commands through Amazon Alexa and Google Home, enabling hands-free operation. The app interface displays real-time voltage, current, power, and cumulative energy data. Users can schedule on/off times and receive alerts for abnormal voltage conditions or leakage events.

The relay is rated for 63A continuous current, with a breaking capacity suitable for typical household circuits. The earth leakage protection function meets international safety standards, automatically disconnecting the load when imbalance is detected. From a performance standpoint, the meter maintains stable WiFi connectivity and updates data at regular intervals. The switching response time is fast, ensuring timely protection against overvoltage or undervoltage scenarios. The energy measurement accuracy is within typical Class 1 or Class 2 tolerance levels, sufficient for cost monitoring and load management.

The device does not require a neutral wire for the WiFi module, simplifying installation in existing panels. The compact form factor fits standard DIN rail mounting, and the terminals are clearly labeled for easy wiring. This smart meter is an affordable solution for homeowners looking to enhance electrical safety and gain insight into their power usage. It offers a practical way to automate energy management without complex hardware.

The compatibility with popular smart home ecosystems adds convenience. The price point provides good value for a multifunctional device that replaces several separate components. It is especially useful for monitoring high-power appliances like water heaters, air conditioners, or EV chargers. The absence of annual subscription fees further adds to its cost-effectiveness.
