NodOn Zigbee Multifunction Relay Switch Review: A Dry-Contact Module for Gates, Boilers and Sockets
The NodOn Zigbee Multifunction Relay Switch is a concealed 14A relay with a potential-free (dry contact) output, built to make an existing circuit smart: a gate, garage door or electric latch, a boiler or water heater, a power socket or a lighting line. It is Zigbee 3.0 and hub-dependent, so it needs a coordinator such as Zigbee2MQTT, Home Assistant or a SmartThings hub, and it supports dry and wet contact wiring plus an impulse mode for motorized access equipment. With no energy metering and no Matter or Apple Home support, it best suits tinkerers and installers already running a Zigbee network who want local, in-wall control of a single circuit.
- Retrofitting gates, garage doors and electric latches
- Boilers, water heaters and immersion heaters
- Home Assistant and Zigbee2MQTT households
- Smart sockets and lighting hidden in flush boxes
One relay per circuit you automate.

Who is the NodOn Zigbee Multifunction Relay Switch for?
This is an installer-friendly module for anyone who wants to add smart control to a circuit that a regular smart switch cannot handle. Its potential-free output makes it the right tool for equipment that is not a simple light: a gate or garage door operator, an electric strike, a boiler or water heater call, or a socket you want to switch remotely. Because it is a flush-mount module, it hides behind an existing wall switch or inside a junction box, and with the optional NodOn DIN Rail Box it also fits the electrical panel. It joins a Zigbee 3.0 network, so it fits households standardizing on Zigbee with a coordinator such as Home Assistant, Zigbee2MQTT, SmartThings or an Amazon Echo with a Zigbee hub.
What the NodOn Zigbee Multifunction Relay Switch offers
The headline is the potential-free output rated up to 14A and 3000W at 230V AC, with integrated zero crossing to soften switching. That rating and the dry contact are what let it drive a boiler, a water heater, a gate or an electric latch instead of only a lamp. It supports dry and wet contact wiring, an optional wired wall switch on its input with automatic detection of monostable or bistable switches, and an impulse mode that turns a short pulse into a gate, garage-door or latch trigger. It is Zigbee 3.0 certified for interoperability across Zigbee ecosystems, it takes over-the-air firmware updates, and Zigbee2MQTT exposes the switch state and a power-on behavior setting, so it returns to a chosen state after a power cut. At 44 x 40 x 16.9 mm and 34 g it slips into a standard flush box.
What to know before you buy
This is a Zigbee device without Wi-Fi, so it needs a Zigbee coordinator and will not work plugged into nothing. It requires a neutral wire at the installation point, and its 14A and 3000W contact rating sets the ceiling for what it can switch. This is the plain version: it has no energy monitoring, which is the separate metering model, and it has no Matter or Apple Home support, so it suits homes already built around Zigbee rather than Apple-first setups. There is no manual on/off button on the module itself, the wall switch on the input is what gives local control, and DIN-rail installation depends on the optional NodOn DIN Rail Box rather than being built in. Plan the impulse mode before pairing a gate or garage door, since switching a motor the wrong way can damage it.
Is the NodOn Zigbee Multifunction Relay Switch worth it?
For a single hard-to-automate circuit, it packs the two things that usually force a bigger purchase: a proper potential-free output and a 14A rating, both in a module small enough to disappear into a flush box. It is the practical pick for boilers, water heaters, gates, garage doors, electric latches and switched sockets, especially in a home that already runs Zigbee2MQTT or Home Assistant. Buyers who want energy data or an Apple Home path should look instead at the metering version or a Matter relay, but for local Zigbee control of one dry-contact load, this does the job cleanly.
Frequently asked questions
Does the NodOn Zigbee Multifunction Relay Switch need a hub?
Yes. It is a Zigbee 3.0 device with no Wi-Fi, so it needs a Zigbee 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 output contacts, so a neutral wire must be available where it is installed.
Can it control a gate, garage door or electric latch?
Yes. Its potential-free output supports an impulse mode for gates, garage doors and electric latches. Activate the impulse mode before pairing, since driving a motor without it can damage the equipment.
Does it monitor energy use?
No. This model has no energy metering. The metering version of the same module is the one that reports power consumption.
Does it work with Apple Home or Matter?
No. It has no Matter support and no native Apple Home path. It reaches Amazon Alexa and Samsung SmartThings, which NodOn lists as compatible, as well as Home Assistant through Zigbee2MQTT.
What can the relay switch?
Its potential-free contact is rated up to 14A and 3000W at 230V AC, covering boilers, water heaters, sockets, lighting and low-power motorized access gear. It can be wired as a dry contact or as a wet contact that passes line voltage to the load.
