Dongle Plus is a universal Zigbee USB stick. It can be used as a Zigbee gateway in Home Assistant, openHAB, Zigbee2MQTT, or other open-source platforms to locally control all your Zigbee devices, so you don’t need to invest in different brands’ Zigbee hubs, all you need is a universal gateway – Dongle Plus!

This auction is the Sonoff Zigbee 3.0 USB Dongle Plus (ZBDongle-P) without retail packaging. I purchased it roughly 2 years ago and tried it for a couple weeks. It has been sitting in a box ever since. I presume it still works as new (haven't got any Zigbee devices to test with but it is detected by my computer). Selling since I don't own or intend to get any more Zigbee devices.
