Moes ZigBee Mini Switch Module Review: A Tiny 10 A Relay That Doubles as a Zigbee Repeater

The verdict

The Moes ZM-104-M is a basic one-channel Zigbee relay in a very small package, and its size is the first thing owners mention: it slips behind an existing switch or into a junction box where bulkier modules do not fit. It switches up to 10 A across a wide 90-250 V range, keeps its state after a power cut, acts as a Zigbee router that extends the mesh, and works with Google Home, Alexa and Home Assistant through a hub. It needs a neutral wire and a Zigbee gateway, has no energy monitoring and no Apple Home or Matter support, and its software quirks (a slight switching delay, a beeper while unpaired, pairing between modules only through the app) make it a good-value tinkerer's part rather than a polished one.

Best for
  • Retrofitting existing light switches
  • Tight back boxes and junction boxes
  • Zigbee2MQTT and Home Assistant setups
  • Extending a Zigbee mesh

Pros

  • Very small and slim, so it fits crowded back boxes and junction boxes
  • Acts as a Zigbee router and extends the mesh, with good range
  • 10 A rating across a wide 90-250 V range
  • Works with Google Home, Alexa and Home Assistant through a hub
  • Pairs without trouble with Zigbee2MQTT and Home Assistant
  • Power-off memory, DIN rail clip and a low price

Cons

  • Requires a neutral wire and a Zigbee hub
  • Connected buttons always toggle the light; no wireless switch mode
  • A short switching delay and a buzzer that beeps until it joins a network
  • A quick run of switch toggles can trigger a hard reset
  • Linking modules directly goes through the app; OTA updates are not offered in Zigbee2MQTT
  • No energy monitoring and no Apple Home, SmartThings or Matter support

Who is the Moes mini module for?

It is for making an existing lighting circuit smart without changing anything visible: the module hides behind the switch or in the junction box, the wall switch keeps working by hand, and the room looks the same. Owners use it for ordinary ceiling lights, for 3-way setups they wired by following the diagram, and as a cheap way to bring a lamp into an existing Zigbee system. Being Zigbee, it needs a hub or gateway rather than a Wi-Fi slot, and it works with Google Home, Alexa and Home Assistant.

What owners like about the Moes mini module

Size comes up more than anything else. Owners call it tiny, and one who swapped an older relay with a radio-frequency receiver said the new one is smaller, faster and quieter when the rocker clicks, with no interference from the old module. It also works as a Zigbee repeater, and owners say connectivity is very good and the range is better than similar modules. People running Zigbee2MQTT or Home Assistant had it pair and switch without trouble, one paired it with a Somfy TaHoma box and used it with voice control and scenarios, and a teardown by a hands-on owner found a 10 A, 250 V relay, a varistor and a fusible resistor at the input with clean soldering, plus a clip that also fits a DIN rail.

What to know before you buy

A neutral wire is required, and one owner points out that it has to be the same neutral that feeds the lights, which is not always reachable in a classic installation. A Zigbee gateway is mandatory; one owner stresses that it only works with a hub. The relay cannot be used separately from its switch input: the connected buttons always toggle the attached light, which matches the missing wireless switch mode on the spec sheet. Hands-on owners also report a switching delay of about a quarter of a second, a buzzer that keeps beeping until the module joins a network, and a hard reset that triggers when the switch input is toggled quickly, which could be set off by a child playing with the switch. Linking several modules directly is done through the app rather than through Zigbee binding, and OTA updates are not offered through Zigbee2MQTT. In a deep junction box, one owner saw the signal drop out repeatedly, and one reported the module failing within minutes after pairing. Another could not pair it with a Philips Hue bridge. The wiring diagram for 3-way setups confused one owner at first.

Is the Moes mini module worth it?

It is cheap and it fits where larger relays do not, which for a retrofit is often the deciding factor, and the mesh routing is a real bonus at this price. What you give up is polish: no energy monitoring, no HomeKit or Matter, a modest switching delay and a few firmware habits that owners find annoying. For a Google Home, Alexa or Home Assistant home with neutral wiring and a Zigbee hub, it is a practical, low-cost way to convert a light switch, as long as you are comfortable with a little tinkering.

Frequently asked questions

Will the Moes mini module fit behind my switch?

It is 18 mm deep and 40 mm square, which is slimmer than most relays, and owners call it tiny. Measure the free depth behind your switch before ordering.

Does it need a neutral wire and a hub?

Yes to both. It needs a neutral wire, and it needs a Zigbee hub or gateway, since there is no Wi-Fi or Bluetooth alternative.

Does it measure energy use?

No. Energy monitoring is not supported on this model.

Will it extend my Zigbee network?

Yes. It works as a Zigbee router, relaying messages for battery-powered devices, and owners report good range.

Which platforms work with it?

Google Home, Alexa and Home Assistant, through a Zigbee hub. Apple Home, SmartThings and Matter are not supported.

Why it needs a Zigbee coordinator

The Moes ZigBee Mini Switch Module 1 Gang speaks Zigbee, not Wi-Fi. On its own it cannot reach your phone, your voice assistant or any automation: it needs a Zigbee coordinator to join. These are the ones in our catalog that can run it.
