Nabu Casa Home Assistant Connect ZWA-2 vs Sonoff ZBDongle-E comparison

Updated August 2026

Data from Amazon and official Nabu Casa and Sonoff sites.

2026 verdict

The Sonoff ZBDongle-E wins this dongle comparison as the cheaper, longer-warranted radio that covers Zigbee, the protocol the Z-Wave-only Nabu Casa Home Assistant Connect ZWA-2 does not touch, and it also doubles as a Zigbee router with 2 years of warranty against 1 year on the ZWA-2. It is the most popular budget Zigbee coordinator for Home Assistant, pre-flashed and plug-and-play with ZHA and Zigbee2MQTT, and a proven way to drop brand hubs like Philips Hue. The two are not interchangeable, though: the Nabu Casa Home Assistant Connect ZWA-2 is a dedicated Z-Wave 800 controller with a stronger antenna (+3.38dBi versus 2dBi) and the standout local Z-Wave range Nabu Casa hardware is known for. Choose the Sonoff ZBDongle-E for an affordable Zigbee coordinator; choose the Nabu Casa Home Assistant Connect ZWA-2 when your devices run on Z-Wave.
