Original product FAQs

Which app is used to control this WiFi MCB, and does it work without the internet?

This device uses the Smart Life / Tuya Smart app (available on Android and iOS) for remote monitoring and control. If the internet is unavailable, you can still operate it manually using the physical override switch on the device itself.

What electrical parameters can I monitor in real time through the app?

The app displays real-time voltage (V), current (A), active power (W), and cumulative energy consumption (kWh). This helps you track usage patterns and identify power-hungry appliances in your home or office.

What is the maximum load capacity, and is it suitable for heavy appliances like ACs and geysers?

This MCB supports up to 80A on a 3-phase supply, making it suitable for heavy-duty loads including air conditioners, geysers, motors, and industrial equipment. Always verify your total connected load does not exceed the rated capacity.

How does the over-voltage and overload protection work?

The device continuously monitors incoming voltage and current. If either exceeds safe thresholds, the MCB automatically trips and disconnects the circuit to protect connected appliances from damage — and sends an alert to your smartphone via the Smart Life / Tuya Smart app.

Is this compatible with Alexa and Google Assistant, and how do I set it up?

Yes, it works with both Amazon Alexa and Google Assistant. Use the voice-assistant linking options provided in Smart Life / Tuya Smart for your device and selected voice service.
