Tuya ZigBee Switch Module without Neutral Wire for 1 to 4 Channel Smart Lights

The Tuya ZigBee Switch Module without neutral wire transforms your traditional system into a smart lighting system without masonry work or running new cables. It works at 230V AC (200–240V) and, depending on the model chosen, offers 1 to 4 independent channels (1CH–4CH) with supported power 10–100 W per channel , perfect for LED lamps, spotlights, wall lamps and chandeliers. Thanks to its operation without neutral wire, it can be easily installed behind the switch or in the 503 box, making it compatible with most Italian home systems. Connected to a ZigBee 3.0 Tuya hub , the module can be managed from the Tuya / Smart Life app like a normal smart WiFi switch : you can turn the lights on and off remotely, check the status of the relays, create timers , daily schedules, countdowns and automatic scenarios (switching on at sunset, switching off at night, simulating presence when you are away from home). Integration with Amazon Alexa and Google Assistant allows voice control of individual light points or groups of lamps, for completely hands-free management. Support for two-way control also allows for the automation of systems with two-way switches (staircase lights, corridor lights, bedroom lights), while maintaining existing mechanical switches: manual control remains available even if Wi-Fi is not present. The ZigBee 3.0 network ensures stable and responsive communication and, by increasing the number of devices, creates a true home automation mesh network throughout the home. Compact, reliable, and easy to install, this module is the ideal solution for those who want to bring home automation for lights to their homes, making indoor and outdoor light points smart without replacing existing buttons and plates.

App control and voice commands with Alexa and Google

Thanks to integration with the Tuya Smart or Smart Life app, you can control the ZigBee switch directly from your smartphone, even when you're away from home: turn lights on and off in real time, create room groups, schedules, and customized scenarios (e.g., leaving home , night , vacation ). Connected to a ZigBee 3.0 gateway , the module becomes fully compatible with Amazon Alexa and Google Assistant , allowing you to manage your lighting with simple voice commands—“Alexa, turn off the living room lights”—for a convenient, hands-free smart home experience. Even in the event of Wi-Fi issues, the lights can still be controlled using the traditional wall switch, ensuring constant control of the system.

Relay status memory after blackout

The Tuya ZigBee switch module lets you choose what your lights do when power returns after a blackout. From the app, you can set whether the load should turn back on , stay off , or resume the last state (on/off) before the power outage when power returns. This relay status setting function is ideal for lamps, spotlights, and controlled sockets: it increases safety, prevents unwanted switching on, and makes the lighting system truly intelligent even in the event of power surges or interruptions.

2-way diverter support: control from the staircase and from the app

The Tuya ZigBee module without neutral is compatible with classic 2-way switches: you can turn the same light on and off from two points (e.g., at the top and bottom of the stairs, in the hallway, or in the bedroom) while maintaining existing mechanical switches. The relay detects every change in the physical control state and synchronizes it with the Tuya / Smart Life app, so the lamp can be controlled both via wall switches and via smartphones or smart automations. This way, you can transform a traditional "two-way" lighting system into a smart lighting system without breaking walls or rewiring.

Automatic time programming and timers

With the Timer Schedule feature in the Tuya / Smart Life app, you can create daily and weekly schedules to automatically turn lights and connected loads on and off, based on your habits. Set them to turn on at sunset, turn off at night, or set a countdown timer for when you go to bed, and the neutral-free ZigBee module will take care of the rest, simulating your presence at home and helping you save energy by preventing lights from being left on for too long.

Requires Tuya ZigBee 3.0 Hub for Connection

The Tuya ZigBee Switch Module without neutral works in combination with a Tuya ZigBee 3.0 hub , essential for pairing and app control. The gateway creates a stable, low-latency mesh network that connects all your smart devices even when Wi-Fi is saturated or poorly covered. Once paired with the hub, the switch appears in the Tuya / Smart Life app and you can manage it remotely, create automatic scenarios with compatible sensors, thermostats and lights and control your home lighting with a single platform, even when you're away from home.

Frequently Asked Questions

1. Do I really need a ZigBee hub? Can I just use it with my home Wi-Fi?

Yes, a Tuya /Smart Life compatible ZigBee 3.0 hub/gateway is required. The module communicates via ZigBee, not Wi-Fi: without a hub, you can't connect it to the app or control it remotely or with Alexa/Google.

2. I don't have a neutral wire in the breaker box, can I still install it?

Yes, that's its strong point: it works without a neutral. Simply connect: the incoming phase (L), the outgoing phase to the lamp (L1, L2, L3, L4), inputs S1...S4, to the switches/buttons. The neutral remains only at the light point/lamp.

3. Can I use it together with a dimmer or other smart modules on the same circuit?

No, it's not a dimmer and shouldn't be used in series with other dimmers or smart switches on the same load. It should be connected as the sole control device for the lamp; if you want to adjust the light intensity, you'll need a dedicated dimmer module and a dimmable lamp.

4. After a blackout, the lights turn on by themselves: can this be changed?

Yes, in the device settings ( Tuya / Smart Life app) you can find the option “Status after power recovery / Relay status”.

5. How does 2-way control (staircase/corridor with two switches) work?

The module supports 2-way control : Connect the module to the lamp.

Connect inputs S1 / S2 to the two mechanical switches/diverters.

This way you can turn the lights on and off both from the app and from traditional switches , without redoing the system.

6. Can I use it together with a dimmer or other smart modules on the same circuit?
