Moes ZigBee Mini Switch Module 2 Gang Review: A Tiny Retrofit Relay That Keeps Your Wall Buttons Working

A compact 2-gang Zigbee relay that hides behind existing switches and pairs with Alexa, Google Home and Home Assistant, if you have a Zigbee hub.

The verdict

The Moes ZigBee Mini Switch Module 2 Gang is a small, hardwired relay designed to fit inside a tight switch box behind an existing wall plate, adding Zigbee control to two lighting circuits while keeping the physical switch working. Buyers consistently highlight how small it is and how easily it pairs with the Tuya Smart Life app, Alexa and Home Assistant once a Zigbee hub is in place, while the main complaints are a small number of units that became unreliable or developed a switching delay after months of use. For anyone retrofitting a couple of existing light switches into a Zigbee smart home without rewiring the wall, it is a solid, space-saving choice.

Best for
  • Retrofitting existing wall switches without rewiring
  • Tight, shallow switch boxes
  • Zigbee and Tuya Smart Life households
  • Keeping physical switches working alongside automation

Pros

  • Very compact size fits tight switch boxes
  • Keeps the existing physical wall switch working
  • Quick pairing with Tuya Smart Life app and Alexa
  • Doubles as a Zigbee router to extend mesh coverage
  • Power-off memory keeps behavior consistent after outages

Cons

  • No Apple HomeKit, SmartThings, Matter or IFTTT support
  • No energy monitoring or dry contact mode
  • Requires a separate Zigbee hub to operate
  • A minority of buyers reported delayed or erratic switching over time

Who is the Moes ZigBee Mini Switch Module 2 Gang for?

This module targets people who want to smarten up two existing light switches without replacing the wall plate or running new wiring. Reviewers describe fitting it into shallow switch boxes thanks to its compact size, and using it to control shop signage on a timer, retrofit lighting circuits, and keep a physical wall button working side by side with app and voice control. Since it requires a Zigbee hub, it is best suited to households already running a Zigbee gateway, whether that is a Moes hub, a Tuya Zigbee gateway, or a platform like Home Assistant.

What buyers love

Buyers repeatedly single out how small the module is, with several noting it fits behind existing switches and outlets where bulkier relays would not. Pairing with the Smart Life/Tuya app and with Alexa is described as quick and reliable, and the wet contact mode that keeps the physical switch functional alongside the smart control is called out as a genuine convenience, letting a button toggle attached lights without losing app or voice control. The unit's small footprint also lets it work as a Zigbee router, which a few buyers note helps extend mesh coverage around the house.

What to know before you buy

A minority of buyers reported real reliability issues: one described a unit that began switching with a several-second delay after about a year of use, another said their unit started rapidly toggling the lights on its own, and one buyer could not find their exact model listed on the manufacturer's site. Installation still needs a sufficiently deep switch box despite the module's small size, and there is no support for Apple HomeKit, Samsung SmartThings, Matter or IFTTT, so it fits best into Alexa, Google Home or Home Assistant setups rather than an Apple-centric one. It also lacks energy monitoring and dry contact mode, so it is built for basic on/off lighting control rather than motor or appliance automation.

Is the Moes ZigBee Mini Switch Module 2 Gang worth it?

For a low-cost way to add Zigbee control to two lighting circuits while preserving the existing wall switch, this module delivers on its core promise for the large majority of buyers, and its compact size is a genuine advantage in cramped switch boxes. The scattered reports of delayed or erratic switching after extended use are worth weighing, but for straightforward retrofits in a Zigbee or Tuya smart home, it remains a practical, budget-friendly pick.
