Sonoff Dongle Max vs Sonoff ZBDongle-P

The Sonoff Dongle Max wins overall thanks to USB, Ethernet and PoE connectivity, a Thread border router and higher +5dBi antennas. The Sonoff ZBDongle-P is the cheaper, slightly higher-rated and longer-warrantied pick, and remains the community's reference USB Zigbee coordinator if you do not need network connectivity or Thread.

Connectivity and chip. The Dongle Max uses the EFR32MG24 and runs over USB, Ethernet or PoE with a Thread border router, while the ZBDongle-P uses the well-supported TI CC2652P over USB only, with no Thread. Both are Zigbee 3.0 coordinators for Home Assistant.

The Sonoff ZBDongle-P has the longer, more proven track record, working cleanly with ZHA and Zigbee2MQTT across almost any host. The Dongle Max is more flexible but has documentation gaps and a login-happy web portal, so it favors users comfortable troubleshooting.

Buy the Sonoff Dongle Max if you want to place your Zigbee coordinator away from the host over Ethernet or PoE, want a Thread border router alongside Zigbee, or need the higher +5dBi antennas to cover a larger home.

Buy the Sonoff ZBDongle-P if you want the community-favorite Zigbee coordinator on the well-supported CC2652P chip, with a +20dBm amplifier for range and a longer 2-year warranty. It does no Thread or Z-Wave and is USB only.
