Hi Everyone.
I had the same issue as above. I’ve tried many things but no luck. I didn’t want to update the firmware on my ZBDongle-E. Finally I’ve found the solution and it works.
The main confusion is that ZBDongle-E uses different chip Silicon Labs EFR32MG21 which uses Zigbee Stack EmberZNet (EZSP v8). Please check ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus V2” (model "ZBDongle-E") based on Silicon Labs EFR32MG21 +20dBm radio MCU now sold for $19.99
In the error log for Zigbee2MQTT it clearly mentioned Zstack, which is other option.
That being said, after explicitly specifying adapter: ezsp Zigbee2MQTT started successfully.
Check this option here Adapter settings | Zigbee2MQTT
Please check and let me know.
My config is below.
