Zigbee2MQTT Installation Issues on HA OS

Hey everyone, I’m new to Home Assistant and I’m trying to integrate Zigbee2MQTT into my setup. I’ve got a Sonoff Zigbee 3.0 USB Dongle Plus and a TI CC2652P + CP2102N Zigbee Gateway. I’ve installed Zigbee2MQTT as an add-on and set up the Mosquitto broker, but I’m running into some issues.

I followed Simon’s video guide, but it didn’t quite work out for me. The latest update of Zigbee2MQTT seems to have changed some configuration settings, and I’m not quite sure how to adjust. I’ve set the device path for my USB stick under the ‘Serial’ port in the Zigbee2MQTT settings, but it still isn’t working.

Here’s what I’m seeing:

[21:28:10] INFO: Preparing to start…
[21:28:10] INFO: Socat not enabled
[21:28:11] INFO: Starting Zigbee2MQTT…
Starting Zigbee2MQTT without watchdog.
Onboarding page is available at http://0.0.0.0:8099/

And the Mosquitto logs show:

2025-11-13 23:21:21: mosquitto version 2.0.22 starting
2025-11-13 23:21:21: Config loaded from /etc/mosquitto/mosquitto.conf.

2025-11-13 23:22:59: New connection from 172.30.32.2:39704 on port 1883.
2025-11-13 23:22:59: Client closed its connection.

I’m stuck and could really use some help. Has anyone else encountered similar issues with the latest Zigbee2MQTT update? Any tips or suggestions would be greatly appreciated! Thanks in advance!
