Phoscon App does not start

  • Platform information:
    • Hardware: RaspBerry Pi 3 Model B Plus Rev 1.3
    • OS: Raspbian GNU/Linux 11 (bullseye)
    • openHAB version: openHAB 3.3.0.M6
    • Notes: System controlled by openHABian latest release. All other SW latest versions installed with openHABian
  • Issue of the topic: Phoscon app (deConz) is running, but cannot be accessed through the web-interface on port 8081 after upgrade to M6 and reboot

What is the output of

netstat -tulpn | grep -i deconz


ps -ef |grep -i [d]econz
tcp        0      0   *               LISTEN      367/deCONZ

root       366     1  0 Jun06 ?        00:06:22 /bin/bash /usr/bin/
openhab+   367     1  1 Jun06 ?        00:22:19 /usr/bin/deCONZ -platform minimal --http-port=80

Somehow the port 8081 that was recommended to be defined when I installed deconz using openHABian was changed back to 80 during the upgrade process from 3.3.0.M5 to 3.3.0.M6

Problem solved, but I don`t know if this changed will cause other problems

I doubt that this is caused by the update of openhab. I could imagine that this happens due to updates of openhabian depending on your setup.

Did you create a file /etc/systemd/system/deconz.service.d/override.conf to define the changed port ?

No, only used opanHABian to install and configure deconz/Phoscon App

The intention of the file
is to define ports that are different from the default ports.
In my case the file looks like:

ExecStart=/usr/bin/deCONZ -platform minimal --http-port=8090 --ws-port=9443

Changes at other locations might be overwritten by updates of the modified files.
