HSW-120Z

Z-Wave Dual Switch Embedded Module

The HSW-120Z is a compact in-wall smart switch module that enables wireless control of two lighting circuits or electrical appliances through Z-Wave networking. Designed to fit behind standard wall switches, it allows users to maintain their original switch panel appearance while upgrading to a smart home automation system.


Developed by HomeScenario, the HSW-120Z integrates seamlessly with Z-Wave controllers and HomeScenario gateways, enabling remote control, real-time status monitoring, and automation through mobile apps or smart home systems.

Product Overview

The HSW-120Z Z-Wave Dual Switch Embedded Module is designed to convert conventional wall switches into smart automation devices. Installed behind a compatible switch panel, the module allows users to wirelessly control two lighting circuits or electrical appliances.


The device supports Z-Wave two-way mesh networking, enabling reliable communication with smart home gateways and controllers. It automatically detects the on/off status of connected loads and reports the status to the central controller, allowing users to monitor and control devices remotely through the internet.


In addition to its switching function, the HSW-120Z also acts as a Z-Wave repeater, extending wireless signal coverage throughout the smart home network.


Its compact design allows it to fit inside standard in-wall electrical boxes and integrate with popular Panasonic switch panels, making it an ideal solution for upgrading existing homes to smart home automation without extensive renovation.
