Moes ZigBee Mini Switch Module Review: A Slim 10 A Relay That Also Repeats Your Mesh
The Moes ZM-104-M is a basic in-wall Zigbee relay done in a usefully thin package: 18 mm deep, which is what decides whether a module actually fits behind an existing switch in a crowded back box. It switches one circuit at up to 10 A across a wide 90-250 V range, keeps power-off memory, mounts on a DIN rail if you prefer a panel install, and acts as a Zigbee router so it strengthens the mesh for battery sensors. It needs a neutral wire and a Zigbee hub, and works with Google Home, Alexa and Home Assistant. There is no energy monitoring and no Apple HomeKit or Matter support.

Who is the Moes mini module for?
It is for making an existing circuit smart without changing anything visible: the module hides behind the switch, the switch keeps working by hand, and the room looks the same. The slim 18 mm profile is the practical differentiator, because retrofit projects usually fail on depth rather than on features. Being Zigbee, it neither uses a Wi-Fi slot nor depends on a cloud account, and it works with Google Home, Alexa and Home Assistant through a hub.
What it offers
One channel switching AC from 90 to 250 V at up to 10 A, in wet contact mode so the load is powered directly. Power-off memory sets the state after an outage, automations run through your platform, and DIN rail mounting means it can also live in a consumer unit rather than a wall box. The quiet bonus is Zigbee router functionality: as a permanently powered device it relays messages for battery sensors, so each module you install makes the mesh a little more reliable.
What to know before you buy
A neutral wire is required, which rules out many older installations, and a Zigbee hub is mandatory with no Wi-Fi or Bluetooth fallback. There is no energy monitoring. Apple HomeKit, SmartThings, IFTTT and Matter are all unsupported. There is no dry contact mode, no interlock or roller mode for shutters, and no wireless switch mode for decoupling the rocker as a scene button. Several specifications are undocumented, including the maximum load in watts, idle consumption, all four protection features, whether there is a manual button, and OTA update support.
Is the Moes mini module worth it?
It is cheap and it fits where bulkier modules do not, which for a retrofit is often the deciding factor. The mesh routing is a genuine bonus at this price. What you give up is documentation and features: no metering, no protection specs stated, and a narrow platform list. 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.
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, so it fits back boxes where bulkier modules do not. Measure the free depth behind your switch before ordering.
Does it need a neutral wire?
Yes, along with a Zigbee hub. 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.
Which platforms work with it?
Google Home, Alexa and Home Assistant. Apple HomeKit, SmartThings, IFTTT and Matter are not supported.
