Zigbee ON/OFF lighting module SIN-4-2-20

Ceiling lights, wall lights, spotlights: the SIN-4-2-20 lighting module fits behind the existing switch or in the false ceiling and makes one or two lighting circuits controllable from your Zigbee gateway, by voice or through scenes.

The problem: lighting that can only be controlled from the wall

Replacing every bulb with a smart model is expensive, and it stops working as soon as the wall switch is turned off. Replacing the switches often means changing the look of a room or an entire building.

The NodOn Zigbee ON/OFF Lighting Module tackles the problem at its source: it is wired into the lighting circuit, keeps the existing switches in place and adds remote control and automation, whatever lamps are installed.

The SIN-4-2-20: two lighting circuits in a single module

In a 40 × 44 × 16.9 mm housing, the module combines two independent outputs, two inputs for wired switches and the Zero Crossing function. It communicates via Zigbee 3.0 with your gateway, your BMS or a compatible ecosystem.

💡 Two channels Two separately controlled outputs, up to 3 A and 690 W each, for one or two lights	〰️ Zero Crossing Switching at the zero crossing of the voltage ensures compatibility with all types of lamps
🎛️ Existing switches kept Each output has its own wired switch input; the module automatically detects whether it is a push button or a standard switch	📶 Zigbee 3.0 Compatible with the main Zigbee gateways and voice assistants, OTA firmware updates

Key point: the module can be mounted behind an existing switch, in a false ceiling or in the consumer unit using the NodOn DIN Rail Box. On the ceiling, it can also be combined with the NodOn DCL Cover. Note: with Alexa, Tydom and Enki (via Lexman), only one of the two channels can be controlled.

Installation: one or two channels

The module is connected to neutral and live, using 1.5 to 4 mm² cables stripped to 8 mm. Depending on the number of lights to be controlled, there are two wiring options:

Option 1

One light

The light is connected to output 1, and the existing wall switch to the corresponding input. The second channel remains available.

Option 2

Two lights

Each light has its own output, and each switch (for example the two rockers of a double switch) its own input. The two circuits are controlled independently.

⚠️ Electrical safety: switch off the power at the consumer unit before any work and do not make any changes while the module's LED is lit. The module must be placed in a compliant junction box and is for indoor use only. If you are not comfortable with electrical installations, call a qualified electrician.

Setup in 3 steps

Wiring and switch detection

With the power off, remove the switch that controls the light or lights, wire the module according to the diagram in the user guide, then refit the switch and restore the power. Next, press each wired switch once: the module automatically detects whether it is monostable or bistable.

Adding it to your Zigbee network

When powered up, the LED flashes orange: the module is looking for a network. Start device discovery on your gateway (Home Assistant, Jeedom, Zigbee2MQTT, Philips Hue, Homey…). Once pairing succeeds, the LED turns green. If no network is found within 15 minutes, it stays orange: a short press on the button restarts the search. The module appears as a Zigbee ON/OFF light (Device ID On/Off Light 0x0100) with two control endpoints.

3	Control and scenes Each channel can be controlled separately from your interface, by voice or in a scene. The wall switches keep working as normal. To get started with a voice assistant, see our tutorial Using the NodOn Zigbee Lighting Module with Amazon Alexa.

What you can automate

🚶 Turning on a corridor or staircase light when presence is detected, then switching it off automatically	🌅 Turning on outdoor lighting at sunset and switching it off at a set time
🏢 Switching off all the lights on a floor or in an office at the end of the day	🏠 Presence simulation during extended absences

The product

The SIN-4-2-20 is installed in the wall, in the ceiling or in the consumer unit and communicates directly with your Zigbee gateway, your BMS or your lighting ecosystem.
