SONOFF New Z-Wave USB Dongle (Dongle-PZG23) with EFR32ZG23 Chip

After releasing several Zigbee dongles over the past few years, SONOFF has stepped into the Z-Wave Dongle with its first product: the Z-Wave 800 Dongle Plus (Model: Dongle-PZG23 ).

The newly listed Dongle-PZG23 is built on the Silicon Labs EFR32ZG23 chip and brings the key advantages of the Z-Wave 800 series , including:

  • Stable and responsive control
  • S2 security for encrypted communication
  • Support for Z-Wave Long Range (ZWLR) for long-distance, point-to-point control

Besides, the adjustable external antenna helps improve overall signal quality, and being able to fine-tune its angle makes it easier to find the best placement—especially useful in setups where USB ports are close to interference sources.

If you’ve been running Z-Wave on Home Assistant or other open-source platforms, this dongle fits right into that workflow.

Dongle-PZG23 is currently running a promotional campaign on SONOFF.tech. The price is $19.9 , which makes it a very affordable way to upgrade to a more powerful Z-Wave 800 series dongle.

Promotional campaign ends on January 18, 2026. If you’ve been waiting for a new Z-Wave USB stick, this might be worth a look.
