Tube's Zigbee Coordinator (EFR32)

Quick verdict

Tube's Zigbee coordinators are a favorite in the Home Assistant community for good reason. The Ethernet option solves the USB interference problem that plagues many Zigbee sticks by letting you place the coordinator anywhere on your network. The EFR32 chip is rock-solid with excellent range. Stock comes and goes since it is a small-batch operation, so buy when available.

Standout: Ethernet connectivity option lets you place the Zigbee coordinator anywhere on your network, away from USB interference and closer to your Zigbee devices.
