Sonoff Orb-MW2 Review: A Matter-over-Wi-Fi Double Switch That Keeps Working Without the Cloud
The Orb-MW2 (MINI-2GS-E) is Sonoff's double switch for Matter over Wi-Fi: a two-gang in-wall unit that controls two lighting circuits separately and commissions straight into Apple Home, Google Home, Alexa, SmartThings and Home Assistant through Matter. It keeps the physical paddle useful even when the relay is decoupled, so a smart bulb downstream stays powered and the button can trigger a scene instead of cutting the circuit. Two constraints decide whether it fits: a neutral wire at the switch box and a resistive load, since Sonoff rates it for resistive circuits only and not for fans, motors or LED drivers. For a Matter-first home that needs two gangs on one plate, it is a value pick.
- Matter-first homes
- Two-gang lighting circuits
- Boxes that carry a neutral wire
- Smart-bulb setups that want the paddle decoupled from the relay
Pros
- Matter over Wi-Fi: commissions into Apple Home, Google Home, Alexa, SmartThings and Home Assistant through a Matter controller
- Two independently controlled channels, 10A per gang and 16A total for resistive loads
- Detach Relay Mode decouples the paddle from the relay so smart bulbs stay powered and the button can trigger a scene
- Configurable power-on state (On, Off, Last State, Reverse Last State) with an optional delay
- Adjustable blue status LED through the eWeLink Network Indicator setting
- Schedules, countdown timers, loop timers, Smart Scenes, group control and local LAN control
- External S1 and S2 switch inputs for a conventional rocker or momentary switch
- Wide 110-240V range and a two-year warranty
Cons
- Requires a neutral wire at the switch box
- Rated for resistive loads only; no inductive or capacitive rating for fans, motors or LED drivers
- No power metering on this model
- 2.4GHz Wi-Fi only, with no 5GHz, Zigbee, Z-Wave or Thread
- A Matter controller or hub is required to use the Matter path
Who is the Sonoff Orb-MW2 for?
This is a two-gang in-wall switch for replacing a standard double light switch with a connected one. It runs Matter over 2.4GHz Wi-Fi, so it commissions into Apple Home, Google Home, Alexa, SmartThings and Home Assistant through a Matter controller rather than a Sonoff-specific bridge, and it also works through the eWeLink app. It suits a wall box with a neutral wire on 110-240V wiring and two lighting circuits to control independently. The two channels share one faceplate and one neutral feed, and the switch keeps a physical paddle for each gang.
What the Sonoff Orb-MW2 offers
Matter over Wi-Fi is the headline: one device joins the major ecosystems directly, with on/off, channel control and Smart Scenes exposed through Matter. Each gang is rated for 10A and the two channels combined for 16A of resistive load. Detach Relay Mode separates the external switch from the relay, so pressing the paddle can leave a smart bulb powered while still sending its command, and the physical switch keeps working locally if the network drops. External S1 and S2 inputs accept a conventional rocker or momentary switch. The unit carries a blue LED that reports pairing, online and offline states, and the eWeLink Network Indicator setting can turn it off. Schedules, countdown timers, loop timers, Smart Scenes, group control and local LAN control are all documented, the power-on state can be set to On, Off, Last State or Reverse Last State with an optional delay, and inching settings auto-off after a chosen duration. It measures 86 x 86 x 33.7 mm and weighs 96.5g.
What to know before you buy
Wiring comes first: the Orb-MW2 needs a neutral wire, and the rating is stated for 110-240V at 50/60Hz, so it suits homes on those voltages with a neutral at the box. It is rated for resistive loads only, up to 10A per gang and 16A total, and Sonoff publishes no inductive or capacitive rating, so fans, motors, LED drivers and similar loads are out. There is no power metering on this model. Connectivity is 2.4GHz Wi-Fi only, with no 5GHz, Zigbee, Z-Wave or Thread, and a Matter controller or hub is required to use the Matter path. The detach relay, inching and indicator fine-tuning live in the eWeLink app, and the warranty runs two years.
Is the Sonoff Orb-MW2 worth it?
For a two-gang Matter switch the Orb-MW2 lands on value: it replaces one dumb double switch, controls two circuits separately and joins every major ecosystem through Matter without a brand hub. The decoupled relay and the physical-paddle fallback are the practical touches that matter day to day, and the wide 110-240V range makes it usable on either side of the Atlantic. The case weakens when the wall box has no neutral, when a load is inductive or capacitive, or when the circuit needs power metering, since those are exactly what this model does not offer. Where a single-gang dimmer or a metered model fits the job better, Sonoff's own Orb line covers that ground.
Frequently asked questions
Does the Sonoff Orb-MW2 need a neutral wire?
Yes. Sonoff states the Orb-MW2 requires a neutral wire for proper installation and operation, so a box carrying only live and load cannot run it.
Does it need a hub?
It is a Matter over Wi-Fi device, so it joins a smart home through a Matter controller or hub, such as an Apple Home hub, a Google or Alexa device that manages the fabric, a SmartThings hub or Home Assistant. It does not depend on a Sonoff Zigbee bridge, and it can also be added to the eWeLink app.
Does it work with Apple Home, Google Home and Alexa?
Yes. Matter is what carries it into all three, along with Samsung SmartThings and Home Assistant. Sonoff documents adding it to each via the Matter QR code.
How many circuits can it control and what loads can it switch?
It has two independently controlled channels, each rated for 10A with a combined maximum of 16A for resistive loads. The rating is stated for resistive loads only, so inductive loads such as fans and motors and capacitive loads such as LED drivers are not covered.
Does it measure how much power the lights use?
No. The Orb-MW2's specification and feature set do not include power metering.
What does Detach Relay Mode do?
It separates the external switch from the relay, so pressing the paddle does not cut power to the circuit. That lets a smart bulb downstream stay powered while the button still triggers a Smart Scene, and the physical switch keeps controlling the load locally if the network goes down.
