Nabu Casa Home Assistant Connect ZBT-2 vs Sonoff ZBDongle-P

Full Smart Dongles comparison in 2026

Updated August 2026
Data from Amazon and official Nabu Casa and Sonoff sites.
2026 verdict
The Sonoff ZBDongle-P wins this dongle comparison as the more affordable, longer-warranted Zigbee workhorse, backing a lower price with 2 years of coverage versus 1 year on the Nabu Casa Home Assistant Connect ZBT-2 and adding Zigbee router use. Built on the well-supported Texas Instruments CC2652P chip, it is the community reference coordinator for Home Assistant, working cleanly with ZHA and Zigbee2MQTT and covering multi-floor homes. Where the Nabu Casa Home Assistant Connect ZBT-2 pulls ahead is versatility and refinement: it is also a Thread border router (the ZBDongle-P is Zigbee only, no Thread), it holds the higher owner rating, and its +4.16dBi antenna tops the ZBDongle-P's 2dBi. Both are USB-only radios with no Z-Wave. Go with the Sonoff ZBDongle-P for a proven, cheaper pure-Zigbee coordinator with a longer warranty; go with the Nabu Casa Home Assistant Connect ZBT-2 if you also want Thread/Matter and a stronger antenna.
