Product information

Description

The Nous B5Z Smart ZigBee Relay Module 1-Channel 8A 2000W with Power Monitoring is an ultra-compact smart device designed to integrate conventional wall switches, lighting, and electrical circuits into a TUYA smart home system. Operating via ZigBee 3.0 technology, this 1-channel relay module supports loads up to 8A and 2000W while offering real-time electricity consumption measurement. It features integrated electrical protections and allows users to retain their existing physical wall switches while adding remote smartphone control and automation scenarios.

Advantages

This smart relay module offers a practical way to modernise an electrical installation without replacing visible wall switches. Its ultra-compact housing allows for discreet installation behind a wall switch or inside junction boxes with limited space. The integrated energy monitoring function provides continuous visibility into electricity usage, helping to track connected loads efficiently. Built-in overcurrent, overvoltage, and undervoltage protections ensure safe operation, while the power state recovery function lets users define the exact operational state after a power interruption.

Suitable for

  • Modernising existing electrical installations while keeping traditional wall switches
  • Integrating lighting circuits into a TUYA ZigBee smart home ecosystem
  • Monitoring the energy consumption of connected electrical loads
  • Automating home lighting with schedules, timers, and smart scenarios
  • Installation in tight junction boxes or behind wall switches due to compact dimensions

When it may not be suitable

This module is not suitable for environments lacking a compatible ZigBee gateway, as the smart functions require this connection to operate. It should also be avoided for electrical loads exceeding 8A or 2000W, as operating beyond these parameters can damage the device.

Key specifications

  • 1-channel smart relay module with electromechanical design
  • Wireless connectivity via ZigBee 3.0 standard
  • Maximum load capacity of 8A and 2000W
  • Operating voltage range of 100–240V AC, 50/60 Hz
  • Electricity consumption measurement function
  • Overcurrent, overvoltage, and undervoltage protection
  • Configurable power state recovery after power outage
  • Compact dimensions of 29 x 34 x 17 mm

How to use

The module is designed for concealed installation behind a conventional wall switch or inside an appropriate junction box. Because it connects directly to mains electricity, installation must be performed by a qualified professional in strict compliance with safety regulations. Once wired and connected to a compatible ZigBee gateway, the module pairs with the smart application to enable remote control, energy monitoring, group management, and automated scheduling alongside your physical switch.

What to consider before purchase

  • Verify the availability of a compatible TUYA ZigBee gateway for smart features
  • Check that the connected electrical load does not exceed 8A or 2000W
  • Ensure adequate physical space behind the wall switch or inside the junction box
  • Confirm that installation will be handled by a qualified electrical specialist

Usage recommendations

Always ensure mains power is completely switched off before attempting any installation or wiring work. Regularly check the energy monitoring data within the app to ensure connected loads operate within safe parameters and standard consumption limits.
