Aeotec Z-Stick 7 vs Sonoff Dongle-PZG23

The Sonoff Dongle-PZG23 is the better overall Z-Wave dongle, with a newer Z-Wave 800 chip, a stronger amplifier, a higher rating and a lower price. The Aeotec Z-Stick 7 remains a solid Z-Wave 700 controller, but the PZG23 leads on nearly every measurable point here.

Generation and range. The Sonoff Dongle-PZG23 uses the Z-Wave 800 chip with Z-Wave Long Range, S2 security and a +20 dB amplifier, while the Aeotec Z-Stick 7 is an older Z-Wave 700 controller with a +9.3 dB amplifier. Both do only Z-Wave.

Yes. The Aeotec Z-Stick 7 and the Sonoff Dongle-PZG23 are both dedicated Z-Wave controllers with no Zigbee, Thread or Matter. Owners who want Zigbee run a separate stick alongside either one.

The Sonoff Dongle-PZG23 is described as plug-and-play, recognized quickly by Home Assistant with no flashing, often running in under ten minutes. The Aeotec Z-Stick 7 usually ships with old firmware that must be updated before use, which is more involved.

Buy the Sonoff Dongle-PZG23 if you want a modern, dependable Z-Wave 800 controller for Home Assistant or openHAB with strong range, Long Range support and S2 security. Use the bundled USB extension cable to keep it away from interference.

Buy the Aeotec Z-Stick 7 mainly if you are migrating an existing Z-Wave 700 network and value its long-term stability, or already own into the Aeotec ecosystem. Otherwise the newer PZG23 is the stronger Z-Wave pick, and plan for a firmware update on the Aeotec.
