Network lost and configuration restore does not help - dresden-elektronik/deconz-rest-plugin GitHub Wiki

Users might experience an unfortunate issue that all devices in the local network gets lost, either during regular operations or directly after a reboot. If this is a persisten issue for you (so not resolved by another reboot, a restart of deconz or occurs quite often), you should double check if you're running at least the corresponding firmwares 0x26580700 (Conbee II and Raspbee II) or 0x26350500 (Conbee I and Raspbee I). Generally, it is always recommendable to run the latest updates (from a DE device as well as deconz perspecitve) as there are constant improvements. As a reference, you may refer to the issue as discussed here.

The below guidance assumes a bare metal Raspbian/Linux installation with a Conbee II. However, the approach should be adaptable to your environment a firmware update and some configuration in deconz GUI. This is a workaround for the Raspbian install. Make sure to use the appropriate firmware for you device. This is a example for the Conbee II. All firmware can be found here

Update Firmware

The latest firmware can be found here

  1. Download firmware file

wget http://deconz.dresden-elektronik.de/deconz-firmware/deCONZ_ConBeeII_0x26580700.bin.GCF

  1. Flash the firmware

Stop deconz before flashing

sudo systemctl stop deconz

sudo systemctl stop deconz-gui

sudo GCFFlasher_internal -d /dev/ttyACM0 -t 60 -f deCONZ_ConBeeII_0x26580700.bin.GCF

Update deCONZ

The method of updating depends a bit on your installation method. If you followed the instructions on Phoscon web page and added the deconz repository, just update and upgrade. However, please remember that, unless you've chosen the the beta branch, any newly implemented changes require some time before being promoted to production.

sudo apt-get update

sudo apt-get --only-upgrade install deconz deconz-dev

sudo systemctl restart deconz (for headless setups) OR sudo systemctl restart deconz-gui (for graphical experience)

In case you did a manual installation of deconz, get the latest package and install it

wget http://deconz.dresden-elektronik.de/ubuntu/beta/deconz-2.05.77-qt5.deb

sudo dpkg -i deconz-2.05.77-qt5.deb

sudo systemctl restart deconz (for headless setups) OR sudo systemctl restart deconz-gui (for graphical experience)

In case the network does still not come up

  1. In deCONZ GUI, click on Leave Network
  2. Open the Network settings
  3. Repeatedly click Save button so the parameters get set
  4. Click Done
  5. Click Join Network

Still no luck

There are very rare cases where all the above still does not bring back the network. That is unfortunate and we apologize. However, in those cases you should re-join all the devices once again and for the last time. It has been reported that after that, the issue has never been experienced again so far.
