Sonoff Zigbee 3.0 USB Dongle Plus-Max - Universal Coordinator for Smart Home and Advanced Automation

TheSonoff Dongle-M is a universal USB Zigbee adapter based on the state-of-the-art EFR32MG21 processor. It acts as a powerful gateway for your smart home network, allowing you to connect dozens of Zigbee devices directly to automation platforms such as Home Assistant, OpenHAB or Zigbee2MQTT, without depending on proprietary hubs from manufacturers.

Key Selling Points

• Universal Matter & Zigbee Compatibility: Dongle-Max is ready for the future. It supports the Zigbee 3.0 standard and can be upgraded to work as a Matter/Thread Border Router, giving you incredible flexibility in managing devices from different brands (IKEA, Philips Hue, Xiaomi, Sonoff etc.).

• Enhanced Performance and Stability: Based on the EFR32MG21 chip, this dongle offers +20dBm signal gain, ensuring a stable connection and extended range throughout your home. It can directly manage up to 32 devices, and with Zigbee routers, the network can be expanded to hundreds of nodes.

• Aluminium Housing for Heat Dissipation: Unlike plastic adapters, the Sonoff Dongle-Max has a rugged metal housing that prevents overheating during continuous operation, ensuring long life and consistent performance.

• Plug & Play for Open Source Platforms: Natively recognised by Home Assistant (via ZHA or Zigbee2MQTT integration), it is the ideal solution for advanced users who want total local control, data protection and elimination of latency caused by cloud services.

• SMA External Antenna: Comes equipped with a detachable external antenna that improves signal reception, enabling efficient communication even through thick walls or at longer distances.

Modes of Use and Automations

1. Central Coordinator: You can use it as the main "brain" of the Zigbee network on a Raspberry Pi or mini-PC system, eliminating the need to buy separate hubs from each brand of sensor.

2. Router (Extender) Mode: With specific firmware, the device can be turned into a Zigbee router. You plug it into any powered USB port (e.g. a phone charger) to extend the reach of the Zigbee signal to remote areas of your home.

3. Total Local Control: By integrating with Home Assistant, you can create complex automations between devices from different brands (e.g. an IKEA motion sensor to switch on a Sonoff light bulb) without depending on an internet connection.
