Sonoff ZBDongle-E on home assistant problem

I am installing Sonoff ZBDongle-E on home assistant using ‘Smart Home Junkie’ YouTube video Install Zigbee2MQTT THE RIGHT WAY with the Sonoff ZBDongle E in Home Assistant - Tutorial”. I am trying to configure the Zigbee2MQTT add-on. I am running HA version 2022.11.2 on a Raspberry Pi 4. I installed a Sonoff ZBDongle E, and when trying to configure Zigbee2MQTT this is the message I get:

'“Failed to save add-on configuration, Missing option ‘serial’ in root in Zigbee2MQTT (45df7312_zigbee2mqtt). Got {‘data_path’: ‘/config/zigbee2mqtt’, ‘socat’: {‘enabled’: False, ‘master’: ‘pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777’, ‘slave’: ‘tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5’, ‘options’: ‘-d -d’, ‘log’: False}, ‘mqtt’: {‘server’: ‘mqtt://core-mosquitto:1883’, ‘user’: ‘mqttuser’, ‘password’: ‘MagiKreb$4me’}}”’

Any help would be appreciated.

Hi, I’m just in the middle of setting this up myself. Have you entered the address of the Dongle?
If you are using the Add-on UI, there will be a section ‘Serial’. Under there you need to paste the /dev/serial/by-id/usb-xxxxxxx address that can be found under the Hardware menu in settings.
