Frequently Asked Questions (FAQ)

Can this smart meter be operated without a Wi-Fi connection?

Yes. In addition to 2.4G Wi-Fi remote management, the device fully supports local manual operation via physical keys and its manual control handle.

Which mobile applications and voice assistants are supported?

The device pairs seamlessly with Tuya Smart and Smart Life applications on iOS/Android, and can be voice-controlled via smart speakers powered by Amazon Alexa, Google Assistant, and Yandex Alice.

What electrical metrics can be monitored in real time?

Users can monitor current (A), voltage (V), leakage current (mA), active power (kW), total cumulative power consumption (kW/h), and real-time device temperature (℃) straight from the mobile interface.

How does the automatic reclosing function work?

When a fault (such as over/under voltage or overload) triggers a protective shutoff, the device monitors the circuit. Once conditions return to safe parameters, it automatically recloses after a preset delay time (5–90 seconds, default 30s) for unattended operation.

What are the adjustable ranges for circuit protection?

You can customize overcurrent (1~63A), over voltage (120~300V), under voltage (80~210V), residual leakage current (10~99mA), and temperature cut-off (10~85℃) directly through the application.

Does this unit support prepaid metering systems?

Yes, a switchable prepaid metering mode is built in, making it ideal for rental properties, sub-metering setups, and managed industrial circuits.
