NodOn Zigbee ON/OFF Lighting Relay Switch Review: A Two-Channel Module That Hides Behind the Switch
The NodOn Zigbee ON/OFF Lighting Relay Switch is a concealed two-channel module that turns one or two lighting circuits smart without any building work: it fits behind an existing wall switch, in a ceiling box or, with the optional DIN Rail Box, in the electrical panel. Each channel switches up to 3A and 690W at 230V AC with integrated zero crossing, so it handles resistive, inductive and capacitive lighting alike, and an optional wired switch can drive either channel on its own. It is a Zigbee 3.0 end device, so it needs a coordinator such as Zigbee2MQTT, Home Assistant, SmartThings or an Echo with a built-in hub, and it requires a neutral at the installation point. With no energy metering and no Matter or Apple Home path, it best suits homes already built around Zigbee that want dependable local lighting control for a fair price.
- Retrofitting existing lighting circuits
- Home Assistant and Zigbee2MQTT households
- SmartThings and Alexa users
- Homes with neutral wiring at the switch box
One relay per circuit you automate.

Who is the NodOn Zigbee ON/OFF Lighting Relay Switch for?
This is a module for anyone who wants to automate lighting that a smart bulb or a new wall switch cannot cover cleanly. Because it hides behind the existing switch, at the ceiling light or in the electrical panel, it keeps the original fixtures and wiring and adds app, voice and automation control on top. Its two independent channels let one unit look after two separate circuits, and each can be paired with a physical wall switch on its own input. It joins a Zigbee 3.0 network, so it fits households with a coordinator such as Home Assistant, Zigbee2MQTT, SmartThings or an Amazon Echo with a Zigbee hub, and its small 44 x 40 x 16.9 mm footprint means it fits standard flush boxes deeper than 30 mm. It suits renovators who want to automate without construction work and households that value local control over a cloud-only light.
What the NodOn Zigbee ON/OFF Lighting Relay Switch offers
The headline is the pair of switching channels, each rated up to 3A and 690W at 230V AC, which covers ordinary lighting loads across resistive, inductive and capacitive types. Integrated zero crossing softens switching at the AC wave crossing, which is what lets it stay compatible with all kinds of lamps, including the LED drivers and transformers that trip simpler relays. Installation is flexible: behind a wired switch, at the ceiling light, or with no wired switch at all, and the two switch inputs accept momentary or toggle wall switches so existing hardware keeps working. It is Zigbee 3.0 certified for interoperability across Zigbee ecosystems, it supports over-the-air firmware updates, and a per-channel power-on behavior lets it return to a chosen state after a power cut. At 33 g it is light enough to hang safely on a short wiring run, and idle draw stays under 1W.
What to know before you buy
This is a Zigbee device with no Wi-Fi and no Bluetooth, so it needs a compatible coordinator and will not work on its own. It also requires a neutral wire at the installation point, which rules out some older no-neutral switch boxes. Its 3A and 690W rating applies per channel, so heavier loads than that are out of scope, and the output switches the mains line rather than offering a potential-free dry contact, so it is not the model to reach for when you need to trigger a garage door or a boiler input. There is no energy metering, no Matter support and no native Apple Home path, so it suits homes already built around Zigbee rather than Apple-first or Matter-first setups. There is no manual button on the module itself, local control comes from the optional wired switch, and DIN-rail installation depends on the optional NodOn DIN Rail Box rather than being built in. Note too that Alexa can only address one of the two channels.
Is the NodOn Zigbee ON/OFF Lighting Relay Switch worth it?
For a concealed, Zigbee-based way to smarten up one or two lighting circuits, it packs the details that matter: two independent channels, a 3A and 690W rating per channel, zero crossing for tricky LED loads and inputs for existing wall switches, all in a module small enough to disappear into a standard box. It is the practical pick for retrofitting ceiling lights and switches in a home that already runs Zigbee2MQTT, Home Assistant, SmartThings or an Alexa hub. Anyone who needs energy data, Matter, or a dry-contact output should look at a metering or multifunction relay instead, but for local, reliable lighting control on a Zigbee network, this does the job cleanly.
Frequently asked questions
Does the NodOn Zigbee ON/OFF Lighting Relay Switch need a hub?
Yes. It is a Zigbee 3.0 device with no Wi-Fi or Bluetooth, so it needs a compatible coordinator or hub such as Zigbee2MQTT, Home Assistant, a SmartThings hub or an Echo with a built-in Zigbee hub.
Does it need a neutral wire?
Yes, it is powered from 230V AC with a line and a neutral terminal, plus the switching outputs, so a neutral wire must be available where it is installed.
How many lights can it control?
It has two independent channels, so it can control one or two lighting circuits, each rated up to 3A and 690W at 230V AC.
Can I still use my existing wall switch?
Yes. The module has two optional wired switch inputs that work with momentary or toggle switches, so an existing wall switch can keep driving each channel, and it can also be installed with no wired switch and controlled entirely wirelessly.
Does it monitor energy use?
No. This lighting relay model has no energy metering.
Does it work with Matter or Apple Home?
No. It is a Zigbee 3.0 device with no Matter support and no native Apple Home path. It works with Home Assistant through Zigbee2MQTT, with Samsung SmartThings, and with Amazon Alexa, which can only control one of its two channels.
