Build Your Ultimate Local Smart Home
The ZBDongle-E Pro Kit combines the robust EFR32MG21 chip with a high-grade 1.5m shielded extension cable. Engineered to block USB 3.0 noise and optimize antenna placement, it guarantees superior stability for your Home Assistant or Zigbee2MQTT system, ensuring fast and reliable connectivity.
Solve Interference & Optimize Signal Coverage

The Problem: USB 3.0 Interference
Why connection drops happen: High-speed USB 3.0 ports on Raspberry Pi and Mini PCs generate radio noise that jams 2.4GHz Zigbee signals. Plugging a dongle directly into the port often leads to network instability and device dropouts.

The Solution: Shielding & Distance
Silence the noise: The included 1.5m shielded extension cable is the cure. By physically distancing the dongle from interference sources and using high-quality shielding, it ensures a clean communication channel for your smart home.

Optimized Placement
Maximize your range: Don’t bury your gateway behind a metal PC case. Use the extension cable to mount the dongle high up or on a wall, maximizing Line-of-Sight (LoS) for better signal coverage across your home.
Hardcore Specs

Next-Gen Power: EFR32MG21 Series 2
Built on the Silicon Labs EFR32MG21 protocol, this dongle is future-proof. It supports significantly higher throughput and more concurrent connections compared to older CC2531 or CC2652 units, making it ideal for growing smart home networks.

+20dBm Signal Gain
Punch through walls. The external SMA interface with a rotatable antenna delivers a powerful +20dBm output gain. Combined with the flexible placement of the extension cable, say goodbye to weak signals.

Cooler Operation, Better Shielding
The sleek aluminum alloy shell isn’t just for looks. It effectively dissipates heat from the high-performance chip and provides an additional layer of RF shielding against Wi-Fi interference.
Dual Function: Coordinator or Router

One Dongle, Two Powerful Modes
Coordinator Mode: Ships ready to act as the “brain” of your Zigbee network.Router Mode: Need more range? Flash router firmware to turn this device into a powerful signal repeater, eliminating dead zones in garages, basements, or backyards.
Performance in Action: Real-World Scenarios

Zero-Lag Local Automation
Experience the power of instant response. With this Zigbee 3.0 dongle, your automations run locally. Lights turn on the very moment you enter a room, with no frustrating cloud delays or dependencies. Your smart home, your rules, your speed.

Unbreakable Offline Reliability
Your internet connection should not be a single point of failure. Because all data and automations are processed locally, your security sensors, alarms, and critical routines keep working perfectly, even when the internet goes down.

No More Network Dead Zones
Unleash the full potential of your smart home. The dongle’s powerful signal provides extensive primary coverage. For larger properties, it can be flashed with router firmware to act as a Zigbee signal repeater, creating a robust mesh network that covers every corner.
Universal Compatibility: One Hub for All Devices

Break free from vendor lock-in.
As a universal Zigbee 3.0 gateway, ZBDongle-E connects seamlessly with thousands of standard Zigbee devices, including sensors, switches, and plugs from SONOFF and other major brands.
Built for Open-Source Freedom

Your Setup. Your Rules. Zero Latency.
The ZBDongle-E is engineered as a universal coordinator, integrating seamlessly with Home Assistant, Zigbee2MQTT, openHAB, and Jeedom. Powered by the standard EmberZNet (EZSP) protocol, it serves as a robust gateway for all your Zigbee 3.0 devices. Whether you are a developer flashing custom firmware or a user building a local, cloud-free smart home, we provide the reliability you need.
Compatibility Note: True plug-and-play on most systems. Manual driver installation (CP2102N/CH9102F) for Windows or macOS is only required in the rare event the device is not automatically recognized.
ELIMINATE USB 3.0 INTERFERENCE & SIGNAL DROPOUTS: Stop unstable connections on your Raspberry Pi or Mini PC. High-speed USB 3.0 ports generate noise that jams 2.4GHz Zigbee signals. This Zigbee 3.0 USB Dongle Plus-E Pro Kit includes a 1.5m (Approx. 5ft) shielded USB extension cable. By physically separating the dongle from noise sources. It is the essential solution for a rock-solid Home Assistant network, perfect for users migrating from cloud hubs to local control.
HIGH-POWER ZIGBEE NETWORK EXTENDER & REPEATER: Go beyond a standard coordinator. While pre-configured as a gateway, this device can be flashed with router firmware to become a professional-grade Zigbee Network Extender. The included cable allows you to mount the dongle high up for maximum Line-of-Sight, while the EFR32MG21 chip delivers a massive +20dBm output. It punches signals through thick concrete walls, eliminating dead zones in garages, basements, or backyards.
POWERED BY SILICON LABS EFR32MG21 FOR MAXIMUM RANGE: Experience wall-penetrating performance. Built on the industry-leading EFR32MG21 (Series 2) chip, this ZBDongle-E gateway significantly outperforms older CC2531 units. The rotatable external SMA antenna and aluminum alloy shell (for superior cooling and interference shielding) ensure reliable coverage for up to 40 direct child devices and 100+ sub-devices, ideal for large, multi-story homes.
PRE-FLASHED FOR HA, ZIGBEE2MQTT, IOBROKER & OPENHAB: Get started in minutes with pre-loaded EZNet 6.10.3 firmware. This Zigbee Dongle offers native plug-and-play integration for these platforms on Linux/Pi. Note for PC: While widely compatible, Windows/macOS ensures reliable connection via a standard driver installation (CP2102N/CH9102F) if not auto-detected. Perfect for beginners building a smart home system without cloud dependency or monthly fees.
UNIVERSAL COMPATIBILITY & 100% LOCAL PRIVACY CONTROL: Break free from cloud servers. As a universal Zigbee 3.0 Coordinator, this Zigbee hub acts as a central brain for thousands of devices. It seamlessly integrates SONOFF sensors (SNZB-01P/02P/03P/04P/06P/02D/02WD/02LD), ZBMINIR2, and diverse standard Zigbee 3.0 devices from major brands. Keep your data private with 100% local control, ensuring automation runs instantly even without the internet.
