Description

Seeed Studio Sonoff ZBDongle-E is a compact Zigbee 3.0 USB dongle built to turn a PC, Raspberry Pi, or home server into a local Zigbee coordinator. Based on the EFR32MG21 Zigbee coordinator platform and shipped with coordinator firmware, the ZBDongle-E is a practical choice for users who want dependable local control, strong signal coverage, and broad software compatibility without relying on a cloud gateway.
