SONOFF Z-Wave 800 USB Gateway Dongle-PZG23 Home Assistant openHAB

The SONOFF Z-Wave 800 Dongle-PZG23 is a compact USB gateway that adds a full Z-Wave 800 Series radio interface to any computer, single-board computer, or home automation server. Based on Silicon Labs' EFR32ZG23 chip (32-bit ARM Cortex-M33, 512 KB Flash, 64 KB RAM), it supports Z-Wave Long Range (ZWLR) technology with a claimed open-terrain range of up to 1,000 m under laboratory conditions. The dongle works out of the box with Home Assistant, openHAB, Z-Wave JS, and other major automation platforms, making it the ideal foundation for a multi-vendor Z-Wave smart home network without any hub lock-in.

Advantages

The EFR32ZG23 chip represents the latest 800 Series Z-Wave generation, delivering improved range, mesh reliability, and interoperability compared to earlier 500/700 series dongles. The external 2 dBi RP-SMA antenna improves signal quality in environments with walls and interference, and the included 1-metre USB extension cable lets you position the dongle away from potential USB 3.0 interference sources for a cleaner RF environment. The aluminum and PC+ABS housing aids heat dissipation during prolonged operation, and Z-Wave S2 encrypted communication keeps your smart home network secure. ESD protection and a reinforced USB connector ensure long-term durability through repeated plug and unplug cycles.

Suitable for

• Home Assistant, openHAB, or Z-Wave JS users expanding their Z-Wave device network without a proprietary hub
• Raspberry Pi and Linux-based home server setups requiring a Z-Wave 800 Series radio interface
• Smart home integrators building flexible, multi-vendor automation systems across large properties

How to use

Connect the Dongle-PZG23 to a free USB port on your server or computer, or use the included 1-metre USB extension cable to position it for optimal signal. Install the appropriate Z-Wave JS or platform driver, then add the dongle as a Z-Wave controller in your automation software (e.g., Home Assistant Z-Wave JS Integration). Pair Z-Wave devices using the software interface. For best range, place the dongle away from USB 3.0 ports, metal enclosures, and other radio transceivers.

Recommendations

Use the SONOFF Dongle-PZG23 with the 1-metre USB extension cable and position it high up on a shelf or wall bracket to maximise Z-Wave mesh coverage; pair it with Z-Wave JS UI for a powerful, open-source controller interface fully integrated with Home Assistant.
