In this review, I will supplement my recent comparison of two USB Zigbee coordinators from Sonoff with another similar device based on the same Zigbee module as ZBDongle E - namely the EFR32MG21. The test was carried out on the same platform, the same method and with the same devices as the coordinators from Sonoff, which makes it possible to compare them all with each other.
