Sleek Design Meets Robust Functionality

The ITEAD Zigbee 3.0 dongle has been crafted for utmost convenience, sporting a size comparable to that of a standard USB flash drive, ensuring it fits seamlessly into your setup without hogging adjacent USB ports. At the heart of this compact powerhouse is the Silicon Labs EFR32MG21 SoC, which boasts superior capabilities in managing extensive networks, especially when contrasted with the older CC2531 chip.

Points to Ponder

Despite the undeniable allure of ITEAD's Zigbee 3.0 dongle due to its affordability and performance, there are a few considerations that potential purchasers should take into account.

A Sacrifice in Range for Compactness

One notable omission is the lack of an external antenna, with the dongle relying entirely on its PCB antenna for connectivity. While this decision contributes to its sleek profile, it does mean the dongle falls short in range compared to devices like the CC2652RB development stick from slaesh, known for its impressive connectivity span. The absence of an option for an external antenna attachment might leave some users wishing for a bit more flexibility in enhancing their device's reach.

Tailored for Enthusiasts, Sans Protective Casing

It's evident that ITEAD's Zigbee 3.0 dongle caters primarily to the DIY crowd, especially those weaving their smart home systems with Home Assistant or similar platforms. This focus is underscored by the dongle's lack of a protective case, a choice that underscores its enthusiast-grade pedigree but might be considered a downside for users concerned about physical durability.

Nonetheless, for those diving into home automation, ITEAD's dongle represents a blend of affordability and capability that's difficult to overlook.

Zigbee2MQTT Compatibility on the Horizon

For now, the ITEAD Zigbee 3.0 USB dongle does not mesh with the stable release of Zigbee2MQTT, but hope glimmers on the horizon. Development efforts are underway to integrate EFR32 chips, including the EmberZNet v8, heralding future compatibility. The more intrepid among us can already experiment with this dongle by venturing into the dev branch of Zigbee2MQTT, though this path may come with the bumps and hiccups typical of pre-release software.

This blend of affordability, practicality, and forward-looking compatibility positions ITEAD's Zigbee 3.0 USB dongle as a compelling choice for anyone looking to enhance their smart home ecosystem without breaking the bank.
