I have not found any solution to this topic, but it makes deconz useless for me. My system is update, it runs on raspian on a Raspi 4. no reboot , no desconnection of the stick does help in any way. I also deinstalled the whole system and set it up new, I deleted all my lights… it always says Firmware not connected. Whats wrong with me, whats wrong with the system? ![Bildschirmfoto vom 2021-12-24 13-06-38](https://forum.phoscon.de/uploads/default/original/1X/95d98c71373a64c1c6924cec63a66a4df475b2a6.png) How can i change this? Does Deconz work on a Raspberry at all? Thats after the restart of the Raspberry: ![Bildschirmfoto vom 2021-12-24 13-27-58](https://forum.phoscon.de/uploads/default/original/1X/c4292c799b95d78d87ca4ce7ccf4622111c3964b.png) ---

Can you share some logs? ---

And have you tried to update the firmware ? It s a new conbee ? ---

There is no new firmware, as far as I can see. I searched the whole sd card for log files. where are those? ---

For me try first that to update the firmware [https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Update-deCONZ-manually](https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Update-deCONZ-manually) Log are on deconz / help / debug view Else you have an headless OS [https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/deCONZ-debug-flags](https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/deCONZ-debug-flags) But if it s a new device, that have never worked, it s probably a firmware issue. ---

No it works but suddenly disconnects and does not come back. Meanwhile I got it working much better, due to the fact using a extension cable for the stick, away from Raspis USB3 ports. Firmware really seems to be actual. Again the question where I can find the log files. I assume I have to activate those first, but I have no glue. ---

Fastest thing to try, install deconz on a PC machine. You will have the GUI, a good way to update the firwmare, and can test the device on another hardware (to check your hardware or your software on the Pi 3) ---

Don know how it works, but here are my logfiles. It is funny as I can control some lights via the Hue Essential app, but not via the gateway (headless) itself.

I don’t see see disconnection on this logs ? You are sure you have not 2 deconz instances runing ? ---

I am sure. It loses connection during operation, Once I stop and start deconz it works, and after a while it is disconnected. Don know how I should get this into a log. The stick is connected via a cable. ---

Ha ok, I did not understand . So all is working fine for somes hours/days, then suddently you have the “firmware not connected” issue ? And if you try to unplug/replug the conbee ? without restarting deconz ? To try if restarting only the gateway and not the application can make something. Are you sure it can’t be power supply issues ? If you are using the GUI, you can check logs during the issue. ---

After a fresh reinstall and moving the stick with a much longer cable away from the raspberry, it seems to work stable. Thanks ---

Hi there, i´m using the RaspBee module and had the same issue. I fashed the firmware again and DeConz is starting correctly. For your information if somebody have the same issue.
