Smart switch module Nous B1Z ZigBee 1-channel (no power metering)

Nous B1Z ZigBee 1-channel smart switch module is an in-wall relay designed to integrate lighting and small electrical loads into ZigBee-based smart home systems. The compact single-channel module installs behind a switch or inside a junction box and uses ZigBee wireless communication for remote control, scene automation, and compatibility with voice assistants through a ZigBee hub. This version does not include power metering and focuses on reliable switching and automation functions.

Advantages

The module offers compact in-wall installation, stable ZigBee connectivity, and a single output channel for straightforward on/off control of lights or small appliances. Its lack of built-in power metering simplifies the device and reduces cost while maintaining quick response for scene activation, timers, and remote switching via a compatible ZigBee gateway.

Suitable for

• Switching LED or incandescent lighting circuits where power monitoring is not required
• Integration into ZigBee smart home scenes and schedules
• Voice control via a ZigBee-enabled assistant or hub
• Use behind existing wall switches or inside ceiling/wall junction boxes

Key specifications

• Control channels: single-channel relay output for on/off switching
• Communication protocol: ZigBee wireless for integration with compatible hubs
• Installation type: in-wall or within junction box, compact form factor
• Load type: suitable for lighting and small resistive or inductive loads (check local wiring limits)
• Power metering: not included in this model

How to use

Install the Nous B1Z module behind an existing wall switch or inside a junction box following local electrical regulations and ensuring power is turned off before wiring. Connect live and load conductors to the module's terminals according to the wiring diagram provided by the manufacturer, then pair the device with a ZigBee hub or gateway using the hub's pairing procedure. After pairing, configure the device in the hub or app to assign it to rooms, scenes, timers, or voice assistant groups for remote control and automation.

Usage recommendations

Ensure the module is installed by a qualified electrician and verify that the connected load does not exceed the switch relay's rated current. Use a compatible ZigBee hub for full functionality, and update hub firmware or device firmware if available to maintain stability and security.
