Hi, I’m new to homeassistant and trying to connect SONOFF Zigbee 3.0 USB Dongle Plus-E Gateway, Universal Zigbee USB Gateway with Antenna for Home Assistant, Open HAB, Zigbee2MQTT etc, Wireless Zigbee 3.0 USB Adapter
I am trying to connect the dongle via integration.
but I keep getting “Failed To Connect”.
Serial device path: /dev/ttyUSB0
Port Speed: 115200
Dataflow control: software
It sees ttyUSB0 ( The Zigbee dongle) but it refuses to connect to it,.
Spent all day and still can’t find a solution.
Thank you for any assistance.
Could you post the error log and describe your devices are involved? I had a similar problem the first time I tried to connect with docker mosquitto, homeassistant and zigbee2mqtt(dongle), and the error was caused by permissions I needed to start with sudo the container with z2m.
The fix was to use the stable path instead: I ran ls -l /dev/serial/by-id/ to find the full device path and updated configuration.yaml to use that. Also made sure my user had permission by adding it to the dialout group (sudo usermod -aG dialout $USER), then restarted. Worked perfectly after that. Hope this helps someone else!
