Winner
Sonoff Zigbee Bridge UltraLast recorded priceSep 1, 2026$79.04
Currently unavailable on Amazon USA
For most buyers the Sonoff Zigbee Bridge Ultra is the better pick of this pair, a cheaper hub with Zigbee built in, Wi-Fi as well as Ethernet and room for 256 devices. It bridges to Matter, carries a 2-year warranty and works with Apple Home, Alexa, Google Home, SmartThings and Home Assistant. Home Assistant Green is the more capable platform: a quad-core computer with 4GB of memory and 32GB of storage that runs Home Assistant itself, open to devices from almost any brand, with ONVIF, RTSP, Node-RED and Tailscale support. It has no radio on board, though, so Zigbee and Thread need a dongle, and it connects by Ethernet only. Pick the Sonoff Zigbee Bridge Ultra for a Zigbee network, and Home Assistant Green to run your whole home locally.

What the differences mean
Zigbee out of the box
The Sonoff Zigbee Bridge Ultra is a Zigbee coordinator from the moment you plug it in. Home Assistant Green needs a separate dongle for Zigbee and Thread, which adds cost and a USB port to plan around.
Hub or platform
Home Assistant Green runs the whole Home Assistant platform, with ONVIF and RTSP cameras, Node-RED and Tailscale. The Sonoff Zigbee Bridge Ultra is a Zigbee hub that hands its devices to other platforms, Home Assistant included.
Network connection
The Sonoff Zigbee Bridge Ultra joins over 2.4 GHz Wi-Fi or Ethernet. Home Assistant Green is Ethernet only, so it sits next to a network port.
Matter
The Sonoff Zigbee Bridge Ultra is a Matter bridge, exposing its Zigbee devices to Apple Home and Google. Home Assistant Green is not marked as a Matter bridge.
Which one to buy if
- you already run Home Assistant and need a Zigbee coordinator
The Sonoff Zigbee Bridge Ultra works cleanly with Home Assistant, its owners say, and handles up to 256 devices.
- you want to leave the cloud and unify many brands
Home Assistant Green runs your automations locally and is open to third-party devices of every kind.
- your Zigbee devices should show up in Apple Home
Its Matter bridge brings them into Apple Home, Google Home and Alexa.
- you want cameras over RTSP or automations in Node-RED
Home Assistant Green supports ONVIF, RTSP, Node-RED and Tailscale.

What owners say
Owners of both devices praise how easily they install and how well they work with Home Assistant. Sonoff Zigbee Bridge Ultra owners single out a far steadier Zigbee network than the older ZB Bridge-P and Matter bridging to HomeKit, and they complain that third-party Zigbee devices such as Hue bulbs may not pair, that the advertised range is overstated and that Alexa or Google can read some sensors inconsistently. Home Assistant Green owners talk about bringing Lutron, Hue, Shelly and cameras into one local dashboard and a silent box that runs within minutes, while their warnings are the software learning curve, the dongle needed for Zigbee and Thread and a subscription for easy remote access.
