Modulo interruttore smart Avatto LZWSM16-W1 ZigBee senza neutro per montaggio da incasso

Avatto LZWSM16-W1 is a 1-channel ZigBee smart switch module for in‑wall installation where a neutral wire is not available. It enables remote control of lighting and compatible loads via the TUYA / Smart Life app or connected ZigBee gateway, and supports voice control through Amazon Alexa and Google Assistant. The compact module fits most installation boxes and supports scheduling, timers, automations and state restoration after power loss.

Advantages

The module uses ZigBee 3.0 for reliable local wireless communication and requires a ZigBee gateway for cloud or app access. Its no‑neutral design allows retrofit installation behind existing switches without rewiring. The device supports one channel with a wide operating voltage range and low-profile dimensions, occupies minimal space in the backbox and can be used in two‑switch (multiway) configurations. It also retains the last state after power interruptions and integrates with TUYA / Smart Life for grouping, sharing and interlock functions.

Suitable for

• Adding remote control to existing in‑wall light switches without a neutral wire
• Retrofit installations in homes and apartments where rewiring is not desired
• Automation and scheduling of single lighting circuits
• Multiway switching setups (two switches controlling one lamp)

How to use

Install the Avatto LZWSM16-W1 behind the existing wall switch or inside the fixture box following local electrical regulations. No neutral wire connection is required. Pair the module with a ZigBee 3.0 gateway and add it to the TUYA / Smart Life app to control the lighting remotely, create schedules, timers and automations. The physical wall switch remains functional for manual control; the app and voice assistants provide additional remote operation.

Recommendations

For stable operation, place the ZigBee gateway centrally and avoid large metal obstacles. Verify the total connected load stays within the 10–100 W range. Use certified installers for in‑wall installation and follow local electrical safety rules. When using multiway switching, ensure correct wiring and test the function after installation.
