Aeotec Z-Stick 10 Pro vs Nabu Casa Home Assistant Connect ZWA-2

The Aeotec Z-Stick 10 Pro is the better overall pick here. It is the more affordable option and adds a Zigbee 3.0 coordinator alongside its Z-Wave 800 controller, so one stick handles both networks. The Nabu Casa Home Assistant Connect ZWA-2 is higher rated and a superb Z-Wave-only radio with standout antenna range, but it cannot do Zigbee, which is why the dual-protocol Z-Stick 10 Pro takes the win.

Zigbee support. Both use a Z-Wave 800 controller with a +20dB amplifier, but the Aeotec Z-Stick 10 Pro also includes a Zigbee 3.0 coordinator, while the Nabu Casa Home Assistant Connect ZWA-2 is strictly a Z-Wave adapter (Nabu Casa sells a separate Zigbee radio). If you want both protocols in one device, that is the deciding factor.

Very similar on the Z-Wave side, since both run the Silicon Labs 800 series with a +20dB amplifier. The Nabu Casa Home Assistant Connect ZWA-2 adds an external antenna that owners say reaches through walls other coordinators could not, so it can have an edge for difficult Z-Wave layouts, while the Z-Stick 10 Pro spreads its strength across two protocols.

The Nabu Casa Home Assistant Connect ZWA-2 is official Home Assistant hardware, so it is effectively plug-and-play, with HA prompting to install the software on insertion. The Aeotec Z-Stick 10 Pro works well with Home Assistant too but usually needs an initial Zigbee firmware update, and its firmware guide is Windows-only.

Buy the Aeotec Z-Stick 10 Pro if you want a single, cheaper stick that covers both Z-Wave and Zigbee for a cloud-free Home Assistant setup, and you do not mind the one-time Zigbee firmware step.

Buy the Nabu Casa Home Assistant Connect ZWA-2 if you only need Z-Wave and want the smoothest official Home Assistant setup plus the external-antenna range that solves dead zones through stucco or glass. It is ideal for large or hard-to-cover homes struggling with Z-Wave reliability.
