Zigbee2mqtt herdsman not starting due to broken pipe

Setup, Configuration and Use Installation
, ,

Hi all,

i am struggeling currently with zigbee2mqtt. Hardware is a conbee2 stick, brand new. I inserted it into my rasperrypi 4, and went to openhabian-config and installed deconz “plugin”. That was working perfectly, the webui started, i was able to add some aqara sensors and everything went fine.

Later, i detected that there is zigbee2mqtt also and this is my intended way, so piping everything via mqtt. So i also installed this in addition (without removing deconz). But zigbee2mqtt never worked then. I had outputs that the access to usb is already occupied. So i stopped all the deconz services. Then, the occupied access to usb was not a problem anymore but herdsman wont start. Somewhen i thought this could be related to the two systems not working in parallel. So i decided to uninstall both and reinstall only zigbee2mqtt once more. I uninstalled deconz by

sudo apt remove deconz

and uninstalled zigbee2mqtt via openhabian-config. I did a fresh reboot and after everything was up, i reinstalled zigbee2mqtt. I adpated the config only to specify my mqtt broker, the usb port + the adapter, as told on the zigbee2mqtt website. But when the service is started, it directly brakes with

error:         z2m: Error: Error: Broken pipe, cannot set

I also detected, that there is also no web frontend (which is configured with the same port as with the inital deconz service).

I searched for hours but did not find a single approach how to further debug or fix this issue.

Could you please give me a hint on how to proceed? Please find all the information in the debug infos below.

Thanks in advance, really appreciate it
Patrick

could you please remove /opt/zigbee2mqtt and install again (to make sure we got no leftovers from former tries)?

Thank you so much. Fixed it! Sometimes it is sooo easy and one still cant make it.

Thanks so much once more
