A small price for a complete wall control
SONOFF Orb-MW1 makes the most sense when the wall switch itself needs replacing. The white 86 × 86 mm face has one round button, giving it a different look from a conventional rocker without adding a screen or a row of controls. It is a straightforward way to put smart switching on the wall.
The exact MINIR4M-E was listed at £17.23 in SONOFF's UK shop and €19.28 in France on September 9, 2026, with tax included and shipping extra. That is an appealing price for a finished control. It connects directly over Wi-Fi Matter, so there is no SONOFF hub to add to the bill, although your chosen home app still needs a Matter controller.
The simplicity is also the limitation: pressing the button switches the load on or off. The circular shape does not make it a rotary dimmer, and there is no energy measurement. If brightness adjustment is what you dislike about your current switch, this purchase will not fix it.
The inexpensive part is the switch
Orb-MW1 needs neutral wiring and a suitable 86-style mounting box. Its body is 34 mm deep before allowing space for the conductors. A qualified installer needs to confirm the box, circuit and local installation requirements; the modest hardware price is not the full cost of replacing a switch.
The maximum 10 A rating is for resistive loads. It is not a blanket approval for any fan or motor that happens to draw less current. We would choose Orb for a known, suitable on/off circuit rather than treat it as a universal wall control.
Smart-bulb control has a catch
The interesting extra is eWeLink's Detach Relay Mode. It lets the physical button trigger scenes while the relay can keep a smart bulb powered. That addresses a real annoyance: someone using the wall switch can otherwise remove the power that the bulb needs for app control.
However, SONOFF says the button resumes direct control when the device goes offline. That fallback can switch the bulb's power again, so this is not an unconditional promise that the bulb will always stay available. Detached scenes are also an eWeLink feature, not a guarantee that the button becomes a configurable scene remote in every Matter app.
For ordinary switching, the extra mode is optional. Buy for the basic wall control first; treat the smart-bulb behavior as a specific feature with limits.
Keep your faceplate if you already like it
The SONOFF MINIR4M is the better direction when your existing switch looks right and you only want to add remote control behind it. Orb earns its place when replacing the visible control is part of the job.
Aqara Light Switch H2 EU is worth considering when the box lacks neutral or you prefer Matter over Thread. That solves a different constraint from Orb's low hardware price. Choose Orb when the wiring fits, Wi-Fi suits the home, and a simple finished on/off button is exactly what you want.
