Sonoff ZBDongle-E vs Sonoff ZBDongle-P

The Sonoff ZBDongle-E wins narrowly as the cheaper, higher-rated stick. The Sonoff ZBDongle-P is very close and runs the community-favorite CC2652P chip that many prefer for larger Zigbee networks, so the choice is mostly about chip preference and price.

Mainly the radio chip. The Sonoff ZBDongle-E uses the Silicon Labs EFR32MG21, while the Sonoff ZBDongle-P uses the Texas Instruments CC2652P. Both are Zigbee 3.0 coordinators with an external antenna, a +20dBm amplifier and a 2-year warranty, and neither does Thread or Z-Wave.

Yes, both are near plug-and-play. The ZBDongle-E ships pre-flashed and is recognized instantly by ZHA, and the ZBDongle-P is the community standard that also works out of the box with ZHA or Zigbee2MQTT. Both benefit from a USB extension cable to reduce interference.

Buy the Sonoff ZBDongle-E if you want the more affordable, higher-rated Zigbee coordinator for a straightforward Home Assistant setup, and you do not have a strong preference for the CC2652P chip.

Buy the Sonoff ZBDongle-P if you specifically want the community's reference Zigbee coordinator on the well-supported TI CC2652P chip, which many favor for medium-to-large homes with many devices. It has the same 2-year warranty as the ZBDongle-E.
