Nabu Casa Home Assistant Connect ZWA-2 vs Smlight SLZB-06p7U

Full Smart Dongles comparison in 2026

Data from Amazon and official Nabu Casa and Smlight sites.
2026 verdict
The Smlight SLZB-06p7U wins this dongle comparison as the far more connected and multi-talented coordinator, offering Zigbee, Thread, a Bluetooth proxy, and USB, Ethernet, Wi-Fi and PoE placement that the USB-only Nabu Casa Home Assistant Connect ZWA-2 lacks. It even supports USB-over-Ethernet, letting it act as a remote radio on your network, and its +5dBi antenna edges the ZWA-2's +3.38dBi. The catch is protocol: these two do not overlap. The Nabu Casa Home Assistant Connect ZWA-2 is a dedicated Z-Wave 800 controller (the SLZB-06p7U has no Z-Wave) with a strong +20dB amplifier and standout Z-Wave range that owners praise. Both work well with Home Assistant. Pick the Smlight SLZB-06p7U for a flexible, network-placed Zigbee/Thread coordinator; pick the Nabu Casa Home Assistant Connect ZWA-2 when you need Z-Wave.
