NodOn Zigbee Multifunction Relay Switch Review: A Small Dry-Contact Relay Owners Trust for Gates, Boilers and Lights
The NodOn Zigbee Multifunction Relay Switch is a concealed single-channel relay with a potential-free output rated up to 14A and 3000W at 230V, and owners mostly rate it a dependable, easy-to-install module. They praise the stable Zigbee connection, the way it works with Home Assistant (through Zigbee2MQTT or ZHA), the dry contact for boilers, water heaters, garage and gate motors, and its fit with Alexa and Philips Hue setups. The complaints are narrower: some units forget their configuration after a power cut, a firmware update can drop pulse mode, Hue bridge pairing needs patience, and the maker's support is slow. It needs a Zigbee hub, a neutral wire and has no energy metering.
- Home Assistant and Zigbee2MQTT households
- Boilers, water heaters and heating control
- Garage doors and gate motors
- Lights behind existing switches
Pros
- Stable Zigbee 3.0 connection with no dropouts for many owners
- Potential-free output for boilers, garage doors, gates and sockets
- Plug-and-play with Home Assistant, including over-the-air updates
- Keeps an existing wall switch working, monostable or bistable
- Acts as a Zigbee router and strengthens the mesh
- Up to 14A and 3000W for resistive loads at 230V
Cons
- Needs a Zigbee hub and a neutral wire; no Wi-Fi
- Some units lose their setup after a power cut or firmware update
- Hue bridge pairing can be fussy, and it appears only as a basic on/off light
- No energy monitoring, no Matter, Apple Home or Google Home support
- No on/off button on the module; DIN rail needs an optional box
- Support is slow for some owners
Who is the NodOn Zigbee Multifunction Relay Switch for?
It is an installer-friendly module for circuits a regular smart switch cannot handle. Owners use it to replace an old dry-contact thermostat for heating, to control a water heater's day and night contactor, to pulse a garage or gate motor, to run a fan timer and to make a lamp smart behind an existing switch. It joins a Zigbee 3.0 network, so it suits homes built around a Zigbee coordinator such as Home Assistant, a SmartThings hub, a Philips Hue bridge or an Alexa device with Zigbee.
What owners like
Stability and simple setup are the most repeated praise. Owners say it pairs quickly, stays connected for months without dropping off the network, and extends the Zigbee mesh as a mains-powered router. Home Assistant users call it plug-and-play, including over-the-air updates, and several pair it with a temperature probe as a heating controller. The dry-contact output is valued because it avoids the bouncing of cheaper relays, the build feels solid, and the terminals accept thicker wires, ideally with ferrules. Several owners also use it with a Philips Hue bridge and an Alexa app, and one owner added it to a Somfy hub as a light.
What to know before you buy
Behavior after a power cut is the most specific complaint: one owner saw units lose their configuration and settle into odd input modes, and another reports that a firmware update drops pulse mode, which must be reset on the module. Owners connecting it to a Philips Hue bridge say pairing can be fussy and that it behaves as a basic on/off light, so it cannot be controlled in the Hue app like a Friends of Hue product, and it cannot be paired to a Hue switch. One owner measured stray voltage across the dry contacts on all four units they bought, so check the contact before wiring it to sensitive control boards. A neutral wire is needed, there is no Wi-Fi, no energy metering, no on/off button on the module, and the module is not Matter, Apple Home or Google Home compatible. The maker's support is described as slow to answer, and a couple of owners received an item that had been opened or was the wrong product, so check what arrives.
Is the NodOn Zigbee Multifunction Relay Switch worth it?
For a single hard-to-automate circuit in a home that already runs Zigbee, it is a well regarded pick that most owners describe as set-and-forget. It is priced above generic relays, which a couple of owners note, but the stable connection and true potential-free output are what they pay for. If you want energy data or a path into Apple Home or Matter, look at a metering or Matter relay instead.
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 hub or coordinator, for example Home Assistant through ZHA or Zigbee2MQTT, a SmartThings hub or an Alexa device with Zigbee.
Does it need a neutral wire?
Yes. It runs on 230V AC and needs a neutral wire where it is installed.
Can it control a gate, garage door or electric latch?
Yes. Its potential-free output can work as a pulsed dry contact, which is how gates, garage doors and electric latches are triggered. Owners also use it for heating and water heater control.
Does it monitor energy use?
No. This model has no energy metering.
Does it work with Apple Home, Google Home or Matter?
No. It works with Amazon Alexa, Samsung SmartThings and Home Assistant, but not with Apple HomeKit, Google Home or Matter. Some owners add it to a Philips Hue bridge, where it shows as a basic on/off light.
Does it keep its settings after a power cut?
It is built to remember its state after a power cut, but a few owners report units that lost their input configuration after an outage or dropped pulse mode after a firmware update, so check it after either.
