Two sonoff Zigbee Stick e, Zigbee ans Thread not working

Hi

I have my home assistant running on proxmox and I am using the sonoff Zigbee E Stick with zigbee2mqtt without issues.
I recently bought the aqara u200 and needed matter support.
So I bought a second Sonoff Zigbee E Dongle and flashed it with openthreadRCP.

When the stick is plugged in and the Open Thread Border Router Add-on is installed (new stick is selected in configuration), the add-on crashes and also zigbee2mqtt stops working.

What could be the issue here?

Thanks!

I just solved the problem.
When i set up zigbee about a year ago i did not specify the device path under “serial”
now it works :slight_smile:
