Meross Smart Wi-Fi Plug vs Sonoff Zigbee Smart Plug S40 Lite

The Sonoff Zigbee Smart Plug S40 Lite comes out ahead overall, winning on a lower price, a higher owner rating, and its ability to act as a Zigbee router that extends mesh network range to other devices. The Meross Smart Wi-Fi Plug remains the better pick for buyers who specifically want two independently controlled outlets or Apple HomeKit support.

Connectivity. The Meross Smart Wi-Fi Plug connects directly to 2.4GHz Wi-Fi with no hub required, while the Sonoff Zigbee Smart Plug S40 Lite needs a Zigbee hub or coordinator to function at all, and in exchange doubles as a Zigbee router that repeats signal to other mesh devices.

No, it only communicates over Zigbee and requires a compatible hub, such as a Sonoff Zigbee Bridge or a Zigbee2MQTT coordinator, to pair and operate. The Meross Smart Wi-Fi Plug, by contrast, connects straight to Wi-Fi with no hub needed.

Only the Meross Smart Wi-Fi Plug can, its two outlets are switched independently from the app, HomeKit, or voice assistants. The Sonoff Zigbee Smart Plug S40 Lite is a single-outlet plug.

Buyers who want to control two nearby devices, like a pair of lamps or holiday lights, from a single Wi-Fi plug with no hub, and who want Apple HomeKit and Siri support alongside Alexa and Google Home.

Buyers who already run a Zigbee network, especially through Home Assistant or Zigbee2MQTT, and want an affordable outlet that also strengthens mesh coverage to distant sensors or outbuildings.
