🌐 Dongle-LMG21: Your Key to Seamless Connectivity

The hardware is built on the EFR32MG21 radio chip, providing a stable Zigbee mesh network that allows for pairing and controlling bulbs, switches, and sensors of various brands within a single system.

The hardware dongle works as Plug & Play on Windows, Ubuntu, and Raspberry Pi systems (including Docker environments). Its external antenna, adjustable up to ≤180°, provides improved range.

It works perfectly with Home Assistant, openHAB, and Zigbee2MQTT for local control of all your Zigbee devices.

Flexible Flashing for Multiple Roles 

For advanced users, flashable firmware (Zigbee NCP/Router, OpenThread RCP, MultiPAN) is available, allowing configuration for multiple network roles as needed.

It also supports firmware updates using the Dongle Flasher tool to switch between various open-source platforms easily.

The pre-installed firmware using the EmberZNet protocol supports the addition of multiple Zigbee devices.

Functions as a Zigbee network router to boost connections and improve the stability of Zigbee devices in your home.

Runs the OpenThread protocol suite and works with a Thread Border Router, supporting the connection and control of Matter (Matter over Thread) devices.

Thanks to the 2-in-1 Zigbee and OpenThread integration, a single hardware dongle allows you to connect and manage both Zigbee and Thread devices simultaneously.

Ultrasonically Welded Compact Design

The Dongle Lite MG21 features a compact and streamlined design. It is 65% smaller than the ZBDongle-E, allowing greater flexibility when plugging it into various USB ports. It can also be flexibly placed using the included USB extension cable.

Powered by EFR32MG21

Stable performance with low energy consumption, fully utilizing its hardware capacity.

Adjustable Antenna

Hidden axis design with adjustable angles, reaching up to 140m of stable coverage in open spaces.

USB Extension Cable

Comes with a 0.5m extension cable, which minimizes electromagnetic interference for a smoother and more reliable experience.
