## Long description

Smart Switch Module ZigBee Avatto LZWSM16-W2 is an in-wall 2-channel relay module for controlling lighting without the need for a neutral wire. Designed for installation behind mechanical switches or inside junction boxes, it operates over ZigBee 3.0 and integrates with TUYA / Smart Life compatible hubs to enable remote on/off control, scheduling, scenes and automations. The compact housing fits most installation boxes and supports voice control via Google Assistant and Amazon Alexa when connected to a ZigBee gateway.
Advantages
The Avatto LZWSM16-W2 offers two independent channels in a compact form factor, eliminating the need for a neutral conductor and simplifying retrofitting in older installations. It supports ZigBee 3.0 for stable mesh networking and works with TUYA / Smart Life for remote control, grouping, device sharing, timers and automation. The module can remember and restore the last state after power loss, and it supports voice control through popular assistants when used with a compatible gateway.
Suitable for
Retrofit of in-wall light switches where no neutral wire is available
Two-circuit lighting control in homes and apartments
Integration into ZigBee smart home systems for scheduling and scenes

How to use
Install the LZWSM16-W2 inside the installation box behind the existing mechanical switches or near the fixture, ensuring live (phase) connections to the module’s input terminals and load connections to the outputs. No neutral connection is required. Pair the module with a ZigBee 3.0 gateway that supports TUYA / Smart Life, then add it to the app to configure channels, timers, groups and automations. After commissioning you can control each channel from the app, via voice assistants (when linked) or using the physical wall switches paired with the module.
Usage recommendations
Use the module with a compatible ZigBee gateway and the TUYA / Smart Life app to access full functionality such as scheduling, grouping and voice control. Verify that total load per channel stays within the specified 10–100 W range and mount the module inside a dry, indoor installation box that matches its compact dimensions. For multiway switching (two switches controlling one lamp), follow proper wiring practices and local electrical regulations; consult a qualified electrician if unsure.
