Smart On-off Device WiFi Monitoring Electricity Statistics Meter 39x39x19mm Black for Home Energy Management Remote Switch Control
Smart On-off Device for WiFi and ZigBee Electricity Monitoring

This intelligent on-off device brings remote control and electricity monitoring to your home or office. Supporting both WiFi and ZigBee models, it helps you track power consumption and switch appliances on or off from anywhere. Measuring just 39x39x19mm, it fits neatly into standard electrical boxes without protruding. The black finish blends into most interiors, and the single-switch design keeps installation straightforward. Whether you are managing home energy or automating small office equipment, this compact meter offers a practical starting point for smart energy management.
Features and Construction

The device is built around reliable wireless connectivity and a compact form factor that suits modern smart homes. Its small footprint and simple design make it easy to integrate into existing setups.
Wireless Connectivity
Choose between WiFi model-1 and WiFi model-2 for standard home network integration, or ZigBee model-1 and ZigBee model-2 for low-power mesh networks that connect with other ZigBee devices. Both options provide remote on-off switching and monitoring without requiring dedicated hubs beyond what the protocol demands.
Compact Dimensions
At 39x39x19mm, this intelligent switch is one of the smallest in its class. It can be installed in confined electrical boxes or behind furniture where space is limited. The exact wiring and mounting method follows standard electrical practice as per local codes.
Black Finish
The black colour is the only option listed. It offers a neutral appearance that suits most home, office, or commercial environments where the switch may be partially visible after installation.
Uses and Placement

This device is suitable for a range of applications where remote monitoring and control of electrical loads is beneficial. Its compact size supports flexible placement.
Home Energy Management
Monitor the electricity usage of individual appliances such as lamps, fans, or small kitchen devices. The provided electricity statistics help you identify high-consumption periods and adjust usage habits accordingly.
Office or Workshop Control
Automate lighting or equipment in small offices, workshops, or server rooms. The WiFi or ZigBee connectivity allows scheduling or manual remote switching without needing to be physically present.
Retrofit and Expansion
Add smart control to existing circuits without replacing larger infrastructure. Multiple units can be installed for multi-point monitoring, though the package includes only one switch per order.
Benefits and Buying Value

The main advantages are the combination of remote control, energy monitoring, and a compact footprint. This device provides a cost-effective entry point into smart home automation.
Energy Usage Insights
By tracking consumption through the statistics meter function, you gain visibility into which devices draw power and when. This can help reduce unnecessary electricity use without guesswork.
Simple Installation
The 39x39x19mm size simplifies placement, and the lack of extra modules means fewer potential points of failure. Basic wiring knowledge is required, but no specialised tools beyond standard electrical equipment.
Network Flexibility
With both WiFi and ZigBee options, you can choose the protocol that best matches your existing smart home ecosystem. ZigBee models may offer lower power consumption and mesh reliability, while WiFi models leverage your existing router without extra hubs.
