I got stucked while upgrading the Wireless Light Control System from Dresden Elektronik through the web interface. The deCONZ software just closed when I invoked an update.

To work with this issue, one can just start the upgrade process manual via CLI. I write it down here, as I haven´t found it documented anywhere else.

  1. Log in to the Raspberry Pi via SSH
  2. Goto /usr/bin
  3. Start the upgrade process via: sudo ./deCONZ-update.sh

The updater will download new firmware files from the dereseden elektronik homepage and flash them directly via GCFFlasher to your system. I am now running on 2.02.05 firmware version.
