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

Overall the Aeotec Z-Stick 10 Pro comes out ahead for versatility and value. It is the more affordable option and adds a Z-Wave 800 controller and a stronger +20dB amplifier, so one stick handles both Z-Wave and Zigbee. The Nabu Casa Home Assistant Connect ZBT-2 is higher rated and the easier plug-and-play choice, but it is Zigbee and Thread only, so the Z-Stick 10 Pro wins for anyone needing Z-Wave too.

The protocols they cover. The Aeotec Z-Stick 10 Pro is a dual Z-Wave and Zigbee stick with no Thread. The Nabu Casa Home Assistant Connect ZBT-2 is Zigbee and Thread (a Thread border router for Matter), but has no Z-Wave controller. So the Z-Stick 10 Pro is the pick for Z-Wave, and the ZBT-2 is the pick for Thread and Matter.

Only the Nabu Casa Home Assistant Connect ZBT-2. It acts as a Thread border router and pairs Matter-over-Thread devices, running Zigbee or Thread (not both at once). The Aeotec Z-Stick 10 Pro covers Z-Wave and Zigbee only, with no Thread or Matter.

On paper the Aeotec Z-Stick 10 Pro has the higher amplifier gain at +20dB, versus the ZBT-2's 10 dBm rating, and adds Z-Wave Long Range. The Nabu Casa Home Assistant Connect ZBT-2 counters with a dedicated external antenna that owners find covers a whole home for Zigbee and Thread, so both reach well in practice.

Buy the Aeotec Z-Stick 10 Pro if you want Z-Wave and Zigbee from a single stick and prefer to spend less. It suits cloud-free Home Assistant users consolidating both protocols, provided you are ready for the initial Zigbee firmware update.

Buy the Nabu Casa Home Assistant Connect ZBT-2 if you want the most seamless official Home Assistant radio for Zigbee and Thread, need Matter support, and value automatic setup and strong antenna range over having Z-Wave in the same device.
