Product detailed description

⚡ Performance and Reliability in a Compact Adapter

Powered by the robust EFR32MG24 SoC chip with 1536 KB Flash memory and 256 KB RAM, it offers significantly more resources compared to previous models. This results in faster automation responses and more stable management of connected devices.

The device comes pre-flashed with Zigbee coordinator firmware, but using the SONOFF Dongle Flasher web tool, you can easily flash it into other modes—such as a Zigbee router, OpenThread RCP, or even a MultiPAN device—all in under a minute.

The package also includes a 1m USB extension cable, allowing for flexible placement and reducing the risk of signal interference.

The Base Adapter for Open-Source Platforms

The Dongle Plus MG24 can serve as the core adapter for popular open-source platforms, supporting the connection and unified management of Zigbee devices across various brands and categories. This makes it easier to build a multi-vendor smart home ecosystem.

Plug and Play with Open-Source Platforms

Its aluminum housing is durable, resisting both corrosion and pressure while offering a sleek, modern look. The integrated 3 dBi antenna can be optimized up to 4.5 dBi, enabling a range of up to 200 meters in an open area. This adapter is an excellent choice for advanced DIY smart home enthusiasts and demanding users seeking a reliable and powerful multi-protocol controller.

Multiple Adapter Variants

The table compares all four Zigbee adapters from SONOFF: Dongle Plus P, Dongle Plus E, Dongle Plus MG24, and the Dongle Max (also known as Dongle M), which features a different design supporting PoE, an ESP32 WiFi and Bluetooth SoC, and the SiLabs MG24 Zigbee 3.0 SoC. 

The main differences between the MG21-based Dongle Plus E and the Dongle Plus MG24 are that the latter performs better with MultiPAN firmware and comes with a USB extension cable, which helps prevent potential interference between USB 3.0 and Zigbee 3.0.
