Smart switch module Avatto LZWSM16-W2 ZigBee — no neutral required, in-wall relay module

Smart Switch Module ZigBee Avatto LZWSM16-W2 No Neutral TUYA

Make it easy to control the lighting in your home. The functional Avatto 2-channel smart switch module allows you to control your lights remotely - using the TUYA / Smart Life app or the voice assistants Google Assistant or Amazon Alexa. It also allows the creation of operating schedules, timers and automations. At the same time, the device is very easy to install - no neutral wire is required. It supports the ZigBee 3.0 communication protocol - a ZigBee gateway (sold separately) is required for its operation.

Many possibilities with the app

You no longer have to worry if you forget to switch off the light before leaving the house - now you can do it with your smartphone! The TUYA / Smart Life app allows you to switch the lights on and off remotely. It also allows you to group switches together and manage more of them at the same time. You can also share your devices with other household members. This way, they too will be able to control the lights remotely! An interlock function is also available.

Additional facilities

Make the lights in your home adapt to your schedule. Using the app, you can easily set a timer or schedule so that the lights automatically turn on at the time you usually get up and turn off when you go to bed. You also have the option to link more devices together and automate their operation. The switch can also remember the last settings and restore them if, for example, there is a power failure.

Hassle-free installation

Thanks to its compact design, the LZWSM16-W2 is compatible with a variety of switch types and fits into up to 95% of the installation boxes on the market. You can also attach it to a lamp. Its installation will not cause you any problems and it does not require a neutral wire. What's more, it is possible to use 2 switches to operate a single lamp, which is ideal, for example, near a staircase. This way, you can conveniently switch on the light on the ground floor and turn it off when you go upstairs!

Voice control

You are kneading a cake, your hands are busy and you need extra light? Or are you already lying in bed and want to go to sleep, but you still need to switch off the light? With Avatto, everything becomes much simpler - the LZWSM16-W2 switch is compatible with the voice assistants Amazon Alexa and Google Assistant. This allows you to control the lighting with simple commands! Now all it takes is a few words to turn the lights off or on - you don't even have to reach for your phone.

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.

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.
