SONOFF Orb-MW1 is the Matter over Wi-Fi smart wall switch of the Fusion series, which complements the traditional wall switch with modern, multi-platform control. A well-known module Sonoff Mini R4M is responsible for the operation, which can be easily replaced in case of failure. Thanks to Matter compatibility, it can be integrated into Apple Home, Google Home, Amazon Alexa, SmartThings and other systems from a single device, so uniform, brand-independent automation can be realized.

The Detach Relay mode ensures that the "smart" light sources do not lose power and connection even when the wall switch is turned off - the lamp can thus still be controlled by automations or by voice. In the event of an Internet outage, local (LAN) control and the operation of the physical switch ensure continuous usability.

The Orb-MW1 is a single-circuit (1-gang) design, operates from a 100-240 V~ network, and has a nominal load capacity of 10 A (≈2400 W @ 240 V). A neutral conductor is required for installation. An ideal choice for smartening up existing lighting circuits, with a fast, practically Plug&Play setting.

Main product features

- Matter compatibility: By supporting the Matter standard, the Orb-MW1 can be seamlessly integrated with Apple Home, Amazon Alexa, Google Home, SmartThings, etc. systems. It allows you to cooperate with Matter devices from other manufacturers and build a unified smart home environment.
- Detach Relay mode: By turning on this function, you can remotely control your smart devices through "Smart Scenes" even if the physical switch is turned off. If the device goes offline, the physical switch immediately takes back full control.
- LAN control: Can be used even without an Internet connection with local (LAN) control.
- Smart Scene: Works seamlessly with SONOFF sensors, switches and other devices, creating a fully connected smart ecosystem with a unified user experience.
- Compatible accessories: The Orb-MW1 is compatible with the switch frames of the SONOFF Fusion series (Orb-2/3 Gang, sold separately), allowing for flexible, vertical or horizontal mounting.

Smart home protocols and platform compatibility

- Supported protocol: Matter over Wi-Fi (2.4 GHz, IEEE 802.11 b/g/n).
- Factory platforms: eWeLink application (quick pairing) or any Matter-compatible app/base center.
- Ecosystems: Apple Home, Google Home, Amazon Alexa, Samsung SmartThings (functions may vary by platform).
- Local operation: LAN control even without internet; physical switch also works in offline mode with full functionality.
- Voice control: Siri / Google Assistant / Alexa via the appropriate platform.

Smart functions

- Timers and countdown: automatic on/off according to set schedules.
- Power-On State: entering the power-on state (e.g. on/off/last state).
- Scenes and automations: eWeLink "Smart Scene" and Matter-based automations; cooperation with SONOFF sensors and switches.
- Detach Relay use: continuous power supply of smart bulbs/smart lamps to maintain connection and voice control.
- Two types of pairing: recording from the eWeLink app or directly from a Matter-enabled app.
