The Dongle Plus (ZBDongle-P) is SONOFF’s Zigbee 3.0 coordinator, which can be connected as a USB adapter to a computer, Home Assistant server, or other smart home hub. The ZBDongle-P provides a stable and reliable Zigbee network, enabling centralized control and integration of multiple Zigbee devices – up to 21 child devices simultaneously, such as sensors, switches, and relays.
One of the biggest advantages of the dongle is that it is based on the CC2652P chipset, which ensures strong radio performance and stable network operation. The external antenna further increases range and signal quality, providing reliable connectivity even in larger homes or across multiple rooms.
The device operates via USB, making installation and use simple with Plug&Play functionality. The ZBDongle-P is especially popular among DIY and advanced users, as it supports various firmware and systems such as Zigbee2MQTT, ZHA, or even Matter (in eWelink Cube OS). This allows users to build their smart home system according to their own needs, even with fully local, cloud-free operation.
