ZigBee 3.0 USB Dongle for Home Assistant

This USB dongle adds a ZigBee 3.0 coordinator to a Home Assistant server. It arrives pre-flashed with EZSP 7.4.5 firmware so the host detects it immediately without manual code entry. The device targets users who want local control of smart sensors, switches and bulbs without relying on cloud bridges.

250m open-space range with two-wall penetration

A 3 dBi extended antenna delivers 250m line-of-sight coverage and penetrates two walls to reach attics or basements. In dense buildings the signal will fade sooner, so very large homes may need additional routers. The dongle manages dozens of mixed-brand ZigBee devices simultaneously.

Multi-protocol flashable via official HA platform

The hardware supports OpenThread and ZigBee and can be re-flashed through the Home Assistant platform when protocols change. Buyers who need Thread-only or Matter-only firmware today should verify the current image before purchase. The dongle is FCC certified and priced 30% below the official SkyConnect ZBT-1.
