A professional Zigbee gateway that connects Zigbee devices to a 2.4GHz Wi-Fi network, turning all your sensors, switches, and plugs into a unified smart home system. It offers higher capacity and better stability, with advanced features like security modes and local scenes that continue to work even when the internet is down.

This is a hub, not a sensor: it is used to connect and manage Zigbee devices within a smart system.

How does it expand the network to 128 devices?

• The gateway can connect 26 devices directly (typical distribution: 10 end devices + 16 router devices, or 26 routers).
• To reach 128 devices: you need Zigbee devices that act as a Router (such as some plugs or switches connected to permanent power), where each router can expand the connection by about 20–32 additional devices depending on the environment.
• Plug-in or permanently powered devices are generally better for strengthening the network and extending the range within the home.

Security Modes

Create a flexible home alarm system using three customizable modes: Home / Away / Sleep. You can define which devices trigger the alarm in each mode (e.g., motion/door/window sensors).

The gateway's buzzer/siren can be used as a local home alarm when a security scenario is triggered.

Stable Local Scenes + RTC Clock

• Local Smart Scene: Timing and Zigbee scene linking execute locally even if Wi-Fi/Internet is disconnected (within Zigbee devices).
• High-Precision RTC: Short power outages do not cause significant time synchronization errors, and schedules resume immediately after power returns.

Compatibility and Supported Devices

Supports Zigbee devices within the SONOFF / eWeLink ecosystem. Common compatible devices include:

Voice assistant support depends on your platform settings; it can be integrated with systems like Alexa, Google Assistant, and SmartThings within the eWeLink ecosystem.

Quick Setup Steps

1. Connect the gateway to power via a 5V/1A USB cable.
2. Add it within the eWeLink app as a Zigbee Bridge.
3. Start pairing Zigbee sub-devices (Quick Pairing) according to each device type.
4. If you have a large number of devices or a large space: add Router devices (such as plugs) to strengthen the network and extend range.
5. Create scenes: automatic lighting, alarm, doorbell, or time schedules.
