SONOFF Z-Wave 800 Dongle Plus – USB Z-Wave Hub with S2 Security for Home Assistant & openHAB

The SONOFF Z-Wave 800 Dongle Plus is a compact USB Z-Wave hub built on the powerful EFR32ZG23 processor. It is designed for secure, stable control of your Z-Wave devices and supports the S2 security protocol for authentication and encryption. This dongle is engineered to minimize interference, helping your smart home devices respond reliably in everyday scenarios.

With Z-Wave Long Range capability, you can reach farther devices directly, reducing the need for additional repeaters and expanding coverage across larger spaces. An external 2 dBi antenna can be angled for optimal signal stability, making it easier to place the dongle in a position that suits your home layout. The unit is plug and play, requiring only a USB port to get started, and it plays nicely with popular open source platforms such as Home Assistant and openHAB, broadening your automation possibilities.
