✨ What Makes This Special

  • Pre-flashed & ready — EZNet 6.10.3 coordinator firmware, works out of the box with ZHA & Z2M
  • EFR32MG21 chip — the same proven chip used in Home Assistant SkyConnect. Rock-solid stability
  • +20dBm output gain — high transmission power for excellent coverage and range
  • Shielded aluminium housing — reduces electromagnetic interference from surrounding devices
  • External SMA antenna — replaceable, adjustable for optimal signal direction
  • Green Power support — works with Zigbee Green Power devices (Hue Tap, energy harvesting)
  • Multi-firmware — flash Coordinator, Router, Thread RCP, or MultiPAN via Dongle Flasher
  • 1 Year Warranty
💡 Best for: First-time Home Assistant users wanting a proven, community-tested coordinator. Also great as a second dongle for extending your Zigbee mesh (flash as Router) or as a Thread RCP.
📌 Tip: For best signal, always use a USB extension cable (sold separately — 1.5m recommended) to keep the dongle away from USB 3.0 ports and metal chassis. This dramatically improves Zigbee reliability.

❓ Frequently Asked Questions

Do I need to install drivers?
On Linux / Raspberry Pi: no, plug and play. On Windows / macOS: you may need to install CH9102/CH343 USB-to-serial drivers. Links are in the Quick Start Guide.
Should I get this or the Dongle Plus MG24?
The Dongle Plus MG24 is the newer model with a more powerful chip (300% more RAM). If buying new, MG24 is recommended. The ZBDongle-E is still excellent and widely supported — great value if on a tighter budget.
Does it include a USB extension cable?
No. We strongly recommend purchasing a separate 1-1.5m USB extension cable. This prevents USB 3.0 interference and dramatically improves signal quality. The newer Dongle Lite MG21 and Dongle Plus MG24 both include cables.
Can I use it as a Zigbee router?
Yes! Flash router firmware via the SONOFF Dongle Flasher. Plug into any USB power source (even a phone charger) and place it to extend your Zigbee mesh range. Great use for a second dongle.
How many devices can it support?
~30 direct children devices in coordinator mode. Add router-capable devices (mains-powered SONOFF switches) to extend the mesh and support hundreds of devices. No hard firmware limit — depends on your platform.
What's included in the box?
1× ZBDongle-E and Quick Start Guide. Note: USB extension cable is NOT included — highly recommended as a separate purchase.
