Core Features & Project-Focused Advantages

Tuya Ecosystem Compatible Multi-Mode Control

Our Tuya compatible smart WIFI switch supports unrestricted remote control via the Tuya APP, alongside local manual operation, giving project managers full flexibility to adjust circuit status on-site or from any location. It also supports voice control integration, making it ideal for smart building and hospitality projects requiring hands-free operation.

Customizable Multi-Level Electrical Protection

This remote control circuit breaker features fully configurable protection thresholds for overvoltage, undervoltage, overcurrent, and overpower events, allowing tailored settings to match the specific requirements of different project loads. It delivers proactive fault prevention to minimize equipment damage and downtime for critical commercial and industrial systems.

High-Precision Energy Metering for Cost Optimization

With 1% voltage/current accuracy and 2% energy metering accuracy, this smart metering WIFI switch enables real-time energy consumption tracking for distributed sites. It empowers commercial and industrial operators to identify wasteful usage, optimize energy habits, and reduce operational costs across multi-site portfolios.

DIN-Rail Mounting for Rapid Project Deployment

The compact DIN-rail design allows for seamless installation into standard electrical distribution cabinets, making it perfect for retrofitting existing systems or new construction projects. Its small form factor saves valuable cabinet space, ideal for high-density deployment in street lighting control cabinets and commercial distribution panels.

Product Operate Guide

Download and register an account on the Tuya APP, designed for centralized management of multiple devices across project sites.

Complete wiring per the standard diagram: connect the upper terminals to the power supply and lower terminals to the load, then power on the device and wait for the indicator light to activate.

10 seconds after power-on, press and hold the pairing button until the WIFI indicator flashes, confirming the device has entered pairing mode.

In the Tuya APP, click the "+" icon in the top right corner to enter the device addition interface, and wait for the app to detect the device.

Select the 2.4G WIFI network for the device to connect to (5G networks are not supported), then click "Next".

Wait for the device pairing process to complete, then follow the in-app prompts to proceed.

Assign the device to the correct project category and set a standardized name for batch management, then click "Finish" to complete setup.

FAQ

Can this smart WIFI switch be deployed in large-scale street lighting projects?

Yes. This device is purpose-built for distributed street lighting control, with unlimited remote control distance, centralized batch management via the Tuya APP, and customizable protection thresholds to adapt to different municipal grid conditions, making it ideal for city-wide street lighting upgrades.

What should we do if the device indicator light does not turn on during project installation?

First, verify correct wiring: the upper terminals are for power input, and the lower terminals are for load connection only. Next, confirm the power supply voltage is within the rated range, and ensure the neutral wire (N) is correctly connected to the grid neutral (not the PE ground wire). If issues persist, power off the upstream supply and recheck all connections.
