Hello Pierre-Gilles.
Thanks for your work.
I upgraded my Sonoff Zigbee 3.0 USB Dongle Plus V2 model « ZBDongle-E » to version 8.0.2 to try to resolve the systematic OTA failures of US outlets and IKEA radar and devices that randomly disappear.
But the URL of the Zigbee2mqtt interface no longer responds and Gladys/MQTT/Zigbee2mqtt are not connecting together
Hi @thierry06 
I made your topic public because it might help others!
The error indicates that the « ezsp » driver is not compatible with firmware versions 8.x.x.
Currently, in Gladys, we don’t yet support the « ember » driver (there’s work by @cicoub13 on the subject, but it’s not available yet). That’s why even if you change the configuration.yaml, Gladys replaces it with « ezsp ».
Normally, rolling back to 7.4.4 should fix the issue. Are you sure you properly restarted Zigbee2mqtt after doing the downgrade? The error in the logs indicates you’re still on 8.x.x, so either the downgrade didn’t work, or you didn’t restart Zigbee2mqtt
Thanks @pierre-gilles
Downgrading to 7.4.4 didn’t fix anything at the time, but everything was working correctly the next morning. And the Lixee and NOUS OTAs went smoothly; only the Ikea radar is still giving trouble. Thanks a lot for your help
